Overview
Typically, LAN-based IP telephones use external power converters located at or near the desktop. The inline-power patch panel eliminates the need for external power sources; it is a standalone chassis that can be co-located with the Catalyst switch to provide -48 VDC power directly to the telephone through existing Catalyst family 10/100BaseTX switching modules. When used with an uninterruptible power supply (UPS), the inline-power patch panel can provide power to the telephone even in a power failure.
The inline-power patch panel has 48 RJ-45 input ports and 48 RJ-45 output ports (see Figure 1). There are two RJ-45 connectors per port for a total of 48 ports. Each input connector is internally connected to a corresponding output connector (input connector 1 is connected to output connector 1, and so on).
The RJ-45 ports serve as the physical network interfaces to the inline-power patch panel. The lower bank of ports provide 10/100-Mbps connection to the switch through RJ-45 connector pins 1, 2, 3, and 6. The top bank of ports provide -48 VDC power to the IP telephones through RJ-45 connector pins 4, 5, 7, and 8, in addition to transparently passing 10/100 Mbps data traffic on pins 1, 2, 3, and 6.

The following tools and equipment are required to install the chassis:
•Number 1, number 2 Phillips, or 3/16-inch flat-blade
screwdriver
•Antistatic mat or antistatic foam
•Your own electrostatic discharge (ESD) grounding strap
or the disposable ESD strap included with the system
Note For more information about ESD, refer to the
Site Preparation and Safety Guide.
The following tools and equipment are required to install the chassis in a rack:
•Rack-mount kit
•Tape measure and level
Rack-Mounting Procedure
Use this procedure to install the inline-power patch panel in a rack.
During this procedure, wear grounding wrist straps to
avoid ESD damage to the unit. Step 1 Prepare for installation as follows:
a. Place the inline-power patch panel on the floor or on
a sturdy table as close as possible to the rack. Leave enough
clearance to allow you to move around the chassis.
b. Use a tape measure to measure the depth of the rack.
Measure from the outside of the front mounting posts to the outside
of the rear mounting strip. The depth must be at least 19.25 inches
(48.9 cm) but not greater than 32 inches (81.3 cm).
c. Measure the space between the inner edges of the left
front and right front mounting posts to ensure that it is 17.75
inches (45.09 cm) wide. (The chassis is 17.5 inches [44 cm] wide
and must fit between the mounting posts.)
d. Open the rack-mount kit and see the component
checklist in Table 3 to verify that all
parts are included.

Note Figure 2 illustrates how to
attach the front of the inline-power patch panel to the rack. You
can also attach the rear of the inline-power patch panel to the
rack, depending on the configuration of your rack.
Step 2 Note that the L brackets connect the chassis to the
rack. You can mount the L brackets to the front or rear mounting
holes of the chassis, depending on which end is in the front of the
rack.
Note Some equipment racks provide a power strip along the
length of one of the rear posts. If the rack has this feature,
consider the position of the strip when planning fastener points.
Before installing the L brackets on the chassis, determine whether
to install the chassis from the front or the rear of the rack.
Attach the left and right L brackets using the four M4 Phillips pan-head screws provided in the rack-mount kit (see Figure 2).
Figure 2 Attaching the L Brackets
Step 3 Install the chassis in the rack as follows:
a. Position the chassis in the rack as follows (see
Figure 3):
–If the chassis front panel is in the front of the
rack, insert the rear of the chassis between the mounting posts
–If the rear of the chassis is in the front of the
rack, insert the front of the chassis between the mounting posts
b. Align the mounting holes in the L bracket with the
mounting holes in the equipment rack.
c. Secure the chassis using six (three per side) 12-24 x
3/4-inch screws through the elongated holes in the L bracket and
into the threaded holes in the mounting post.
d. Use a tape measure and level to ensure that the
chassis is installed straight and level.

Cabling
This section provides cabling guidelines for
connecting the inline-power patch panel to the
Catalyst switch and IP telephones.
|
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. Use caution when connecting cables.
|
Note The inline-power patch panel should only be used to
provide power to IP telephones, not 10/100 adapters. If the IP
telephone has a power source, you can attach the telephone directly
to the 10/100BaseTX port on the Catalyst switch. However, if the IP
telephone has a local power source, the inline-power patch panel
provides backup power when the local power fails or is removed.
Use these guidelines for your cabling connections (see Figure 4):
•Use standard Category 3 or Category 5 UTP cable.
•Connect a cable from the IP telephone to an RJ-45 port
in the top bank of ports.
•Connect a second cable to the corresponding RJ-45 port
in the lower bank of ports, and then connect the other end of this
cable to a 10/100BaseTX port on the Catalyst switch.

Verifying the Installation
•Before connecting the cables, verify that all the port
LEDs are amber and the status LED is green.
•After connecting the cables from the inline-power
patch panel to the Catalyst switch and IP telephone, verify that
the port LED and status LED are both green.
•Verify the link on the
switch through the inline-power patch panel to the
telephone.
•Verify that the IP telephone powers up and the screen
displays "Cisco Systems."
