Warning Only trained and
qualified personnel should be allowed to install, replace, or service this
equipment. Statement 1030

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
Rack-Mounting Configuration Guidelines
Each CSACS-1121 Series appliance has a set of rack handles (installed at the factory). You will use these handles later when you install the appliance in a 4-post rack. You can front (flush) mount or mid-mount the appliance in a 19-inch (48.3-cm) equipment rack that conforms to the 4-post rack specification (the inside width of the rack should be 17.5 inches [44.45 cm]).
Mount the appliance in the brackets. When the appliance is installed in the rack, it requires one EIA 1.75-inch (4.4-cm) vertical mounting space or 1 rack unit (RU) for mounting.


The Rack Installation Safety Guidelines and the following information will help you plan the equipment rack configuration:
- When mounting an appliance in an equipment rack, ensure that the rack is bolted to the floor.
- Because you may install more than one appliance in the rack, ensure that the weight of all the appliances installed does not make the rack unstable.


- As mentioned in Airflow Guidelines, maintain a 6-inch (15.2-cm) clearance at the front and rear of the appliance to ensure adequate air intake and exhaust.
- Avoid installing appliances in an overly congested rack. Air flowing to or from other appliances in the rack might interfere with the normal flow of cooling air through the appliances, increasing the potential for overtemperature conditions within the appliances.
- Allow at least 24 inches (61 cm) of clearance at the front and rear of the rack for appliance maintenance.


- Follow your local practices for cable management. Ensure that cables to and from appliances do not impede access for performing equipment maintenance or upgrades.

Note The rack-mount
hardware kit does not include a 2-post equipment rack.
Mounting the CSACS-1121 Series Appliance in a 4-Post Rack

Warning When the
appliance is installed in a rack and is fully extended on its slide
rail, it is possible for the rack to become unstable and tip over,
which could cause serious injury. To eliminate the risk of rack
instability from extending the rail or in the event of an
earthquake, you should affix the rack to the floor.

Connecting the Network Interface

Warning Do not work on
the system or connect or disconnect cables during periods of
lightning activity. Statement 1001
This section describes how to connect the CSACS-1121 Series appliance Ethernet port.
The Ethernet connector supports Serial over Lan (SOL). The RJ-45 port supports standard straight-through and crossover Category 5 unshielded twisted-pair (UTP) cables. Cisco does not supply Category 5 UTP cables; these cables are available commercially.
To connect the cable to the appliance Ethernet port:
Step
1 Verify that the appliance is turned
off.
Step
2 Connect one end of the cable to the
Gigabit Ethernet 0 port on the appliance.
Step
3 Connect the other end to a switch in your
network.
Ethernet Port Connector
The CSACS 1121 Series appliance comes with two integrated dual-port Ethernet controllers. ACS 5.4 supports multiple NICs. See Multiple Network Interface Connector for more information. These controllers provide an interface for connecting to 10-Mb/s, 100-Mb/s, or 1000-Mb/s networks and provide full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet LAN.
To access the Ethernet port, connect a Category 3, 4, 5, 5E, or 6 unshielded twisted-pair (UTP) cable to the RJ-45 connector on the back of the appliance.
Table 4-2 describes the UTP cable Categories.
Table 4-2 Ethernet Cabling Guidelines
EIA Categories 3, 4, or 5 UTP (2 or 4 pair) up to 328 ft (100 m) |
|
EIA Category 6 UTP (recommended), Category 5E UTP or 5 UTP (2 pair) up to 328 ft (100 m) |
Figure 4-9 shows the Ethernet RJ-45 port and plug.
Figure 4-9 RJ-45 Port and Plug

Table 4-3 lists and describes the RJ-45 pin signals used on the connector.
Multiple Network Interface Connector
ACS 5.4 with the SNS-3415, Virtual machine, or CSACS-1121 platform allows you to use up to four network interfaces: Ethernet 0, Ethernet 1, Ethernet 2, and Ethernet 3.

Note You need to make
sure that the Ethernet 0 interface is up and running successfully,
to avoid system failure.
Table 4-4 lists the ACS 5.4 functional interfaces which are distributed among the network interfaces.
CS management functions use only the Ethernet 0 interface, whereas authentication, authorization, and accounting (AAA) protocols use all of the configured network interfaces. You must connect the ACS nodes in the distributed deployment only to Ethernet 0. The syslog messages are sent and received at the log collector’s Ethernet 0 interface. Data forwarding from one interface to another interface is prohibited to prevent potential security issues. The external identity stores are supported only on the Ethernet 0 interface. In ACS 5.4, multiple network interface connectors are also supported for the RADIUS and TACACS+ proxy functionalities.
The CLI and ACS management interfaces are accessible from both Ethernet 0 and Ethernet 1 interfaces if you configure both the Ethernet 0 and Ethernet 1 interfaces with IP addresses from the same subnet. Therefore, to restrict CLI and ACS management interface only to Ethernet 0 interface, the IP addresses for the Ethernet 0 and Ethernet 1 interfaces should be from different subnets.
Configuring Multiple Network Interfaces
By default, Ethernet 0 interface takes the IP address that is assigned for ACS. However, for the other Ethernet ports, you must configure the IP address manually.
To configure the IP address for Ethernet ports, complete the following steps:
Step
1 Login to the ACS CLI using the CLI
username and password.
Step
2 Enter su admin
to enter in to the EXEC mode.
Step
3 Enter config t
to enter in to the configuration mode of the ACS CLI.
Step
4 Enter the command interface
GigabitEthernet <interface_number>.
Step
5 Enter the command no shutdown to bring the
interface up.
Step
6 Enter the command ip address <IP
address> <Subnet Mask>.
The console displays the following message:
Changing the IP may result in undesired side effects on any installed application(s).
Are you sure you want to proceed? Y/N [N]:
The specified interface is configured with the given IP address.
ACS restarts automatically. Wait for some time to make sure that all the processes are up and running successfully.
In an IPv6 enabled network, the Ethernet interfaces other than Ethernet 0 use an IPv6 address. If you want to use IPv4 address for the other Ethernet ports, you must configure IPv4 addresses using the ip address <IPv4 address> <IP-Mask> command as described above.

Note ACS 5.4 supports
IPv4 and IPv6 dual stack networking and does not support pure IPv6
network.
Connecting the Console

Warning Do not work on
the system or connect or disconnect cables during periods of
lightning activity. Statement 1001
Your CSACS-1121 Series appliance has a DCE-mode console port for connecting a console terminal to your appliance. The appliance uses a DB-9 serial connector for the console port.
The console port on the CSACS-1121 Series appliance includes an EIA/TIA-232 asynchronous serial (DB-9) connector. This serial console connector (port) allows you to access the appliance locally by connecting a terminal—either a PC running terminal-emulation software or an ASCII terminal—to the console port.
To connect a PC running terminal-emulation software to the console port, use a DB-9 female to DB-9 female straight-through cable.
To connect an ASCII terminal to the console port, use a DB-9 female to DB-25 male straight-through cable with a DB-25 female to DB-25 female gender changer.
To connect a terminal or a PC running terminal-emulation software to the console port on the CSACS-1121 Series appliance:
Step
1 Connect the terminal using a
straight-through cable to the console port.
Step
2 Configure your terminal or
terminal-emulation software for 9600 baud, 8 data bits, no parity,
1 stop bit, and no hardware flow control.
Serial (Console) Port Connector
The CSACS 1121 Series appliance has one serial port connector located on the back panel of the appliance.
Figure 4-10 shows the pin number assignments for the 9-pin, male D-shell serial port connector located on the back panel of the appliance. These pin number assignments are those defined for RS-232-C and conform to industry standards.
Figure 4-10 Serial Port Connector

Table 4-5 lists and describes the serial (console) port pinout.
Connecting the Keyboard and Video Monitor

Warning Do not work on
the system or connect or disconnect cables during periods of
lightning activity. Statement 1001
This section describes how to connect a keyboard and video monitor to the CSACS-1121 Series appliance.
As an alternative to the keyboard and video monitor, you can use a serial console to connect to the CSACS-1121 appliance.
The CSACS-1121 appliance does not provide support for a mouse.
The CSACS-1121 provides USB ports on the front and rear of the appliance that can be used to connect a keyboard and video monitor.
To connect a keyboard and video monitor to the appliance:
Step
1 Verify that the appliance is turned
off.
Step
2 Connect the end of the keyboard cable to
the PS/2 (keyboard) port which is located on the back panel of the
appliance.
Step
3 Connect the end of the video monitor cable
to the PS/2 (video monitor) port which is located on the back panel
of the appliance.
Step
4 Power on the appliance.
Cable Management
Cable management is the most visual aspect of your appliance setup. However, cable management is often overlooked because it can be time consuming.
Equipment racks and enclosures house more equipment today than ever before. This growth has increased the need for organized cable management both inside and outside the rack. Poor cable management not only leads to damaged cables or increased time for adding or changing cables, but also blocks critical airflow or access. These problems can lead to inefficiencies in the performance of your equipment or even downtime.
There are many solutions to address cable management. They can range from simple cable management rings, to vertical or horizontal organizers, to troughs and ladders.
All CSACS-1121 Series appliance cables should be properly dressed so as not to interfere with each other or other pieces of equipment. Use local practices to ensure that the cables attached to your appliance are properly dressed.
Proceed to the next section, Powering Up the CSACS-1121 Series Appliance, to continue the installation process.
