Installing Memory and Power Over Ethernet in
Cisco 880 Series Integrated Services Routers
Warning
Note Memory and PoE are the only upgradable options in the Cisco 880 Series ISR. Do not remove or install
Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.
Statement 1
This document describes how to install memory and Power over Ethernet (PoE) in a Cisco 880 Series

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

Warning
Read the installation instructions before connecting the system to the power source. Statement 1004
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
Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF
or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables,
detach the end away from the unit first. Statement 1026

Warning
Caution Ensure that the PoE power supply is not connected to the back of the router prior to installation of the
Step 1 Open the chassis according to the instructions in “Opening the Chassis” section on page 8.
Installation of the equipment must comply with local and national electrical codes.
Voltages that present a shock hazard may exist on Power over Ethernet (PoE) circuits if
interconnections are made using uninsulated exposed metal contacts, conductors, or terminals.
Avoid using such interconnection methods, unless the exposed metal parts are located within a
restricted access location and users and service people who are authorized within the restricted
access location are made aware of the hazard. A restricted access area can be accessed only through
the use of a special tool, lock and key or other means of security.
To install the power supply card, perform the following steps:
PoE card. Failure to do so may result in damage to the PoE card or to the router.

Step 2 Locate the three metal standoff holes on the system board. See Figure 4 for the location of the PoE
connector. Two standoff holes are identified by a star pattern surrounding the hole; the third hole has a
screw attached to it.

Step 4 Install the three metal standoffs, provided in the accessory kit, into the three standoff holes, as shown in
Figure 5. Use a 1/4-inch nut driver to tighten the standoffs.
Caution Make sure that the standoffs are straight when installed. Tighten them gently but firmly. The shoulder of
each standoff must be seated tightly against the system board.

Caution When installing the PoE card, ensure that the card is installed in the proper direction. Improper
installation will damage the PoE card. Installation of the PoE card requires the installation of three metal
standoffs, to which the card is then secured by using three screws. Be sure to use all three screws to
ensure that the card is installed properly.

Opening the Chassis
Tip If the card is not installed in the correct direction, the three screw holes will not match up with the three
metal standoffs.
Step 5 Place the PoE card on top of the three metal standoffs, lining up the screw holes in the PoE card with the
metal standoffs.
Step 6 Push the PoE card down towards the system board until it is firmly fixed into the PoE connector.
Step 7 Insert the screws provided in the accessory kit through the PoE card and into the metal standoffs. See
Figure 5. Carefully tighten the screws with a Phillips screwdriver.
Step 8 Close the router (see Closing the Chassis, page 10), and then connect the PoE power supply to an AC
power outlet. To connect the PoE power supply to an AC power outlet, see the Cisco 860 and Cisco 880
Series Hardware Installation Guide, Connecting Power over Ethernet.
Opening the Chassis
To open the chassis, you will need a number-2 Phillips screwdriver, a wrist strap, and an antistatic mat.
Warning
During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly
touch the backplane with your hand or any metal tool, or you could shock yourself.
Statement 94
Follow these steps to open the chassis:
Step 1 Disconnect the power supply cable.
Step 2 Disconnect all cables from the router back panel.
Step 3 Use the number-2 Phillips screwdriver to remove the screws at the middle on the back panel, and at the
sides of the router. Figure 6 shows the location of the screws. The screws are in the same location on all
Cisco 880 series ISRs.
