General Precautions

Observe the following general precautions for using and working with your appliance:

  • Observe and follow service markings. Do not service any Cisco product except as explained in your appliance documentation. Opening or removing covers that are marked with the triangular symbol with a lightning bolt may expose you to electrical shock. Components inside these compartments should be serviced only by an authorized service technician.
  • If any of the following conditions occur, unplug the product from the electrical outlet and replace the part, or contact your authorized service provider:

The power cable, extension cord, or plug is damaged.

An object has fallen into the product.

The product has been exposed to water.

The product has been dropped or damaged.

The product does not operate correctly when you follow the operating instructions.

  • Keep your appliance away from radiators and heat sources. Also, do not block cooling vents.
  • Do not spill food or liquids on your appliance, and never operate the product in a wet environment.
  • Do not push any objects into the openings of your appliance. Doing so can cause fire or electric shock by shorting out interior components.
  • Use the product only with other equipment approved by Cisco.
  • Allow the product to cool before removing covers or touching internal components.
  • Use the correct external power source. Operate the product only from the type of power source indicated on the electrical ratings label. If you are not sure of the type of power source required, consult your service representative or local power company.
  • Use only approved power cables. If you have not been provided with a power cable for your appliance or for any AC-powered option intended for your appliance, purchase a power cable that is approved for use in your country.

The power cable must be rated for the product and for the voltage and current marked on the product’s electrical ratings label. The voltage and current rating of the cable should be greater than the ratings marked on the product.

  • To help prevent electric shock, plug the appliance and power cables into properly grounded electrical outlets. These cables are equipped with three-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cord, use a three-wire cord with properly grounded plugs.
  • Observe extension cord and power strip ratings. Make sure that the total ampere rating of all products plugged into the extension cord or power strip does not exceed 80 percent of the extension cord or power strip ampere ratings limit.
  • Do not use appliance, or voltage converters, or kits sold for appliances with your product.
  • To help protect your appliance from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptible power supply (UPS).
  • Position cables and power cords carefully; route cables and the power cord and plug so that they cannot be stepped on or tripped over. Be sure that nothing rests on your appliance cables or power cord.
  • Do not modify power cables or plugs. Consult a licensed electrician or your power company for site modifications. Always follow your local or national wiring rules.

Safety with Equipment

The following guidelines will help ensure your safety and protect the equipment. However, this list does not include all potentially hazardous situations, so be alert.

Warning Read the installation instructions before connecting the system to the power source. Statement 1004

  • Always disconnect all power cords and interface cables before moving the appliance.
  • Never assume that power is disconnected from a circuit; always check.
  • Keep the appliance chassis area clear and dust-free before and after installation.

  • Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
  • Do not wear loose clothing that may get caught in the appliance chassis.
  • Wear safety glasses when working under conditions that may be hazardous to your eyes.

Safety with Electricity

Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security.
Statement 1017

Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Statement 1021

Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected. Statement 4

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. Statement 43

Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. Statement 12

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001

Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. Statement 39

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

Follow these guidelines when working on equipment powered by electricity:

  • Locate the room’s emergency power-off switch. Then, if an electrical accident occurs, you can quickly turn off the power.
  • Disconnect all power before doing the following:

Working on or near power supplies.

Installing or removing an appliance.

Performing most hardware upgrades.

  • Never install equipment that appears damaged.
  • Carefully examine your work area for possible hazards, such as moist floors, ungrounded power extension cables, and missing safety grounds.
  • Never assume that power is disconnected from a circuit; always check.
  • Never perform any action that creates a potential hazard to people or makes the equipment unsafe.
  • Never work alone when potentially hazardous conditions exist.
  • If an electrical accident occurs, proceed as follows:

Use caution, and do not become a victim yourself.

Turn off power to the appliance.

If possible, send another person to get medical aid. Otherwise, determine the condition of the victim, and then call for help.

Determine whether the person needs rescue breathing, external cardiac compressions, or other medical attention; then take appropriate action.

In addition, use the following guidelines when working with any equipment that is disconnected from a power source but still connected to telephone wiring or network cabling:

  • Never install telephone wiring during a lightning storm.
  • Never install telephone jacks in wet locations unless the jack is specifically designed for it.
  • Never touch uninsulated telephone wires or terminals unless the telephone line is disconnected at the network interface.
  • Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD can occur when electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. Always follow ESD-prevention procedures when removing and replacing modules:

  • When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are ready to install the component in your appliance. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.
  • When transporting a sensitive component, first place it in an antistatic container or packaging.
  • Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.
  • Ensure that the CSACS-1121 Series appliance is electrically connected to earth ground.
  • Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the appliance to channel unwanted ESD voltages safely to ground. To guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
  • If no wrist strap is available, ground yourself by touching a metal part of the appliance.

Caution For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. It should be between 1 and 10 Mohm.

Lifting Guidelines

The CSACS-1121 Series appliance weighs between 15 lb (9.071 kg) and 33 lb (14.96 kg) depending on what hardware options are installed in the appliance. The appliance is not intended to be moved frequently. Before you install the appliance, ensure that your site is properly prepared so you can avoid having to move the appliance later to accommodate power sources and network connections.

Whenever you lift the appliance or any heavy object, follow these guidelines:

  • Always disconnect all external cables before lifting or moving the appliance.
  • Ensure that your footing is solid, and balance the weight of the object between your feet.
  • Lift the appliance slowly; never move suddenly or twist your body as you lift.
  • Keep your back straight and lift with your legs, not your back. If you must bend down to lift the appliance, bend at the knees, not at the waist, to reduce the strain on your lower back muscles.
  • Lift the appliance from the bottom; grasp the underside of the appliance exterior with both hands.

Preparing Your Site for Installation

Before installing the CSACS-1121 Series appliance, it is important to prepare the following:

Step 1 Prepare the site (see Site Planning) and review the installation plans or method of procedures (MOPs).

Step 2 Unpack and inspect the appliance.

Step 3 Gather the tools and test equipment required to properly install the appliance.


This section contains:

Site Planning

Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security.
Statement 1017

Typically, you should have prepared the installation site beforehand. As part of your preparation, obtain a floor plan of the site and the equipment rack where the CSACS-1121 Series appliance will be housed.

Determine the location of any existing appliances and their interconnections, including communications and power. Following the airflow guidelines (see Airflow Guidelines) to ensure that adequate cooling air is provided to the appliance.

All personnel involved in the installation of the appliance, including installers, engineers, and supervisors, should participate in the preparation of a MOP for approval by the customer. For more information, see Method of Procedure.

The following sections provide the site requirement guidelines that you must consider before installing the appliance:

Rack Installation Safety Guidelines

The CSACS-1121 Series appliance can be mounted in most four-post telephone company (telco-type), 19-inch equipment racks that comply with the EIA standard for equipment racks (EIA-310-D). The distance between the center lines of the mounting holes on the two mounting posts must be 18.31 inches +/- 0.06 inch (46.50 cm +/- 0.15 cm). The rack-mounting hardware that is included with the appliance is suitable for most 19-inch equipment racks or telco-type frames.

Note Cisco strongly recommends using four-post racks whenever possible, but your rack must have at least two posts that provide mounting flanges for mounting an appliance.

Figure 3-1 shows a couple of common examples of four-post equipment racks.

Figure 3-1 Four-Post Equipment Rack Types

Four-Post (Partially-Enclosed) Rack

Image “1” in Figure 3-1 shows a freestanding, partially-enclosed rack with two mounting posts in the front and two more at the rear. The CSACS-1121 Series appliance may be installed in this type of enclosed rack, because the appliance only requires an unobstructed flow of cooling air into the front of the chassis and pushed out of the rear to maintain acceptable operating temperatures for its internal components.

Four-Post (Open) Rack

Image “2” Figure 3-1 shows a freestanding, four-post open rack with two mounting posts in front and two mounting posts at the back. The mounting posts in this type of rack are often adjustable so that you can position the rack-mounted unit within the depth of the rack rather than flush-mount it with the front of the rack.

Before installing your CSACS-1121 Series appliance in a rack, review the following guidelines:

  • Two or more people are required to install the appliance in a rack.
  • Ensure that the room air temperature is below 95°F (35°C).
  • Do not block any air vents; usually, 6 inches (15 cm) of space provides proper airflow.
  • Plan the appliance installation starting from the bottom of the rack.
  • Do not extend more than one appliance out of the rack at the same time.
  • Connect the appliance to a properly grounded outlet.
  • Do not overload the power outlet when installing multiple devices in the rack.
  • Do not place any object weighing more than 110 lb (50 kg) on top of rack-mounted devices.

Site Environment

The location of your appliance and the layout of your equipment rack or wiring room are extremely important considerations for proper operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. Plan for access to front and rear panels of the appliance.

The following precautions will help you plan an acceptable operating environment for your appliance and will help you avoid environmentally caused equipment failures:

  • Ensure that the room where your appliance operates has adequate circulation. Electrical equipment generates heat. Without adequate circulation, ambient air temperature may not cool equipment to acceptable operating temperatures. For more information, see Airflow Guidelines.
  • Ensure that the site of the rack includes provisions for source AC power, grounding, and network cables.
  • Allow sufficient space to work around the rack during the installation. You need:

At least 3 feet (9.14 m) adjacent to the rack to move, align, and insert the appliance.

At least 24 inches (61 cm) of clearance in front of and behind the appliance for maintenance after installation.

  • To mount the appliance between two posts or rails, the usable aperture (the width between the inner edges of the two mounting flanges) must be at least 17.7 inches (45.0 cm).

Note The rack-mount kit does not include a 2-post equipment rack.

  • Use appropriate strain-relief methods to protect cables and equipment connections.
  • To avoid noise interference in network interface cables, do not route them directly across or along power cables.
  • Always follow ESD-prevention procedures as described in Preventing Electrostatic Discharge Damage to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.

Airflow Guidelines

To ensure adequate airflow through the equipment rack, it is recommended that you maintain a clearance of at least 6 inches (15.24 cm) at the front and the rear of the rack. If airflow through the equipment rack and the appliances that occupy it, is blocked or restricted, or if the ambient air being drawn into the rack is too warm, an overtemperature condition within the rack and the appliances that occupy it can occur.

The site should also be as dust-free as possible. Dust tends to clog the appliance fans, reducing the flow of cooling air through the equipment rack and the appliances that occupy it. This reduction increases the risk of an overtemperature condition.

Additionally, the following guidelines will help you plan your equipment rack configuration:

  • Besides airflow, you must allow clearance around the rack for maintenance.
  • When mounting an appliance in an open rack, ensure that the rack frame does not block the front intakes or the rear exhausts.

Temperature and Humidity Guidelines

Table 3-1 lists the operating and non-operating environmental site requirements for the CSACS-1121 Series appliance. The appliance normally operates within the ranges listed; however, a temperature measurement approaching a minimum or maximum parameter indicates a potential problem.

Maintain normal operation by anticipating and correcting environmental anomalies before they approach critical values by properly planning and preparing your site before you install the appliance.

Power Considerations

You configure the CSACS-1121 Series appliance with AC-input power only. Ensure that all power connections conform to the rules and regulations in the National Electrical Codes (NECs), as well as local codes. While planning power connections to your appliance, the following precautions and recommendations must be followed:

  • Check the power at your site before installation and periodically after installation to ensure that you are receiving clean power (free of spikes and noise). Install a power conditioner if necessary.
  • The AC power supply includes the following features:

Autoselect feature for 110-V or 220-V operation.

An electrical cord for all appliances. (A label near the power cord indicates the correct voltage, frequency, current draw, and power dissipation for the appliance.)

Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). Statement 13

  • Install proper grounding to your host equipment rack to avoid damage from lightning and power surges.

Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

  • The AC-input power supply that operates on input voltage and frequency within the ranges of 100 to 240 VRMS and 50/60 Hz without the need for operator adjustments. Table 3-2 provides additional information on electrical inputs.

Ethernet and Console Port Considerations

ACS 5.4 supports multiple network interface connectors. There are four Ethernet connectors on the rear panel of the CSACS-1121 Series appliance. See Multiple Network Interface Connector for more information on multiple network interface connectors. The Gigabit Ethernet ports use UTP cables. Cisco recommends Category 5 UTP cable. The maximum segment distance is 328 feet (100 meters). The UTP cables look like the cables used for ordinary telephones. However, UTP cables meet certain electrical standards that telephone cables do not. Cables are not included.

The appliance includes an asynchronous serial console port, which enables you to access the appliance locally (using a console terminal). This section describes important cabling information that must be considered before connecting a console terminal—either an ASCII terminal or a PC running terminal-emulation software—to the console port.

Note The console cable is not included with the CSACS-1121 Series appliance.
