Chapter 9 Removal and Replacement Procedures
Preventing Electrostatic Discharge Damage
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. Port adapters and processing modules
consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI)
shielding and connectors are integral components of the carrier. Although the metal carrier helps to
protect the board from ESD, use a preventive antistatic strap during handling.
Following are guidelines for preventing ESD damage:
•Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
•Connect the equipment end of the strap to an unfinished chassis surface.
•When installing a component, use any available ejector levers or captive installation screws to
properly seat the bus connectors in the backplane or midplane. These devices prevent accidental
removal, provide proper grounding for the system, and help to ensure that bus connectors are
properly seated.
•When removing a component, use any available ejector levers or captive installation screws to
release the bus connectors from the backplane or midplane.
•Handle carriers by available handles or edges only; avoid touching the printed circuit boards or
connectors.
•Place a removed component board-side-up on an antistatic surface or in a static shielding container.
If you plan to return the component to the factory, immediately place it in a static shielding
container.
•Avoid contact between the printed circuit boards and clothing. The wrist strap only protects
components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
•Never attempt to remove the printed circuit board from the metal carrier.
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be
between 1 and 10 megohm (Mohm).
Supported Hardware
The Cisco SCE 8000 platform supports the following hardware:
•One Service Control Module (Cisco SCE 8000-SCM-E), with an optional redundant Service Control
Module (FRU).
•One SPA jacket module (Cisco SCE 8000-SIP), with either two or four SPA 10 GBE interface
modules (all FRU).
•Up to two optical bypass modules installed in the bottom slot of the chassis.
•Hot-swappable fan assembly, redundant AC-input or DC-input power supplies.

Statement 289
Note Because the power requirement of the Cisco SCE 8000 does not exceed 1350 W, it is not necessary to
connect two pairs of input wires to each power supply. Should it be desired to connect two pairs of input
wires, both pairs of input wires for one 2700W DC-input power supply must come from the same battery
system (A feed); and both pairs of input wires for the other power supply must come from another battery
system (B feed).
Note For multiple DC input power supplies, each DC input must be protected by a dedicated circuit breaker
or fuse. The circuit breaker or fuse should be sized according to the power supply input rating and local
or national electrical code requirements.

Step 5 Remove the four screws securing the terminal block cover, and slide the cover off of the terminal block.
(See Figure 9-5.)
Figure 9-5 DC-Input Front Panel for 2700-W DC-Input Power Supply
Step 6 Attach the appropriate lugs to the DC-input wires and ground wire. The wires should be sized according
to local and national installation requirements. Use only copper wire. The maximum width of a lug is
0.600 inch (15.2 mm).
Note Use fine-stranded copper conductors rated for 90°C (194°F) for North American installations.
Note The power supply terminal block lug opening width is 0.62 inch (15.8 mm). The terminal posts are
centered 0.625 inches (15.88 mm) apart and are 1/4-20 threaded. We recommend that you use an
appropriately sized industry standard 2-hole, standard barrel compression lug. The power supply ground
studs, located below the terminal block, are also threaded 1/4-20 and require two 1/4-inch split-ring
washers and two 1/4-20 hex nuts.
