Safety Warnings
Warning Definition
Electrical Equipment Guidelines
Follow these basic guidelines when working with any electrical equipment:
•Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.
•Disconnect all power and external cables before moving a chassis.
•Do not work alone when potentially hazardous conditions exist.
•Never assume that power has been disconnected from a circuit; always check.
•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
•Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are improperly handled, can result in complete or intermittent failures. The AC-input power shelf and its AC power modules contain a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the cards from ESD, use an anti-static strap each time you handle the modules.
Following are guidelines for preventing ESD damage:
•Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Before removing a card from the chassis, connect the equipment end of the strap to a bare metal, unpainted surface on the chassis or rack-mount.
•Handle components by the carrier edges only; avoid touching the card components or any connector pins.
•When removing a module, place it on an anti-static surface or in a static-shielding bag. If the module will be returned to the factory, immediately place it in a static-shielding bag.
•Avoid contact between the modules and clothing. The wrist strap protects the card from ESD voltages on the body only; ESD voltages on clothing can still cause damage.
Caution For safety, periodically check the resistance value of the anti-static strap. The measurement should be between 1 and 10 megohms.
Removing and Replacing the Cisco LCD Module
Follow this procedure to replace an existing Cisco LCD module and module ribbon cable. You do not need to power down the system to perform this procedure.
Caution If you are replacing the ribbon cable, you may need to remove the fan assembly, too. The ribbon cable connection to the backplane is reached most easily through the top of the chassis where the fan module is located. This procedure should be done as quickly as possible, because it requires removing the cooling elements from the chassis. Review Cisco uBR10012 Fan Assembly Module documentation at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/cable/ubr10k/ubr10012/frus/index.htm
Equipment
To remove and replace an individual Cisco LCD module you need the following:
•Replacement Cisco LCD module, product order number UBR10-DSPL=
•Phillips head screwdriver #1
•ESD-preventive wrist strap
•Anti-static surface
Note You do not need the cable if you are only replacing the Cisco LCD module.
Unpack the LCD Module
Step 1 Make sure that you are properly grounded with an ESD-preventive ground strap.
Step 2 Remove the Cisco LCD module from the box and packaging.
Step 3 Place the module on an anti-static surface close to the chassis.
Step 4 Remove the cable from its packaging.
Step 5 Place the cable on an anti-static surface close to the chassis.
Remove the LCD Module
Caution When you are removing the front cover, watch that the key caps on the front of the LCD are not dislodged or otherwise damaged.

Step 3 Pull the module out of the chassis until you can reach the ribbon cable plugged into the back of the module.
Step 4 Disconnect the cable from the connector and place the module on an anti-static surface.
Step 5 If you are replacing the cable and the module, or if you are replacing just the cable, see the "Replace the LCD Ribbon Cable" section.
Replace the LCD Module
Step 1 Hold the module up close to its location in the chassis.
Step 2 Attach the ribbon cable to the back of the module. See Figure 5 for connector location.
Note The ribbon cable is designed to fold into the chassis as you put the module back into place.
Step 3 Align the screw holes in the module with the screw holes in the chassis.
Step 4 Insert the screws (one at a time starting with the top) in the screw holes.
Step 5 Hand tighten the screws with the screwdriver. Do not over tighten or torque the screws down.
Caution The key caps are easily dislodged. Be careful when reinstalling the front cover.
Step 6 Carefully replace the front cover on the chassis.
