5.3 Replacing the Bridge Board

The CG2100 server bridge board provides the fan tachometer and SAS/SATA signal paths

between the front panel board and the baseboard. Because it spans both the front panel

board and the baseboard, several components must be removed before you can replace the

bridge board:

• Both top chassis covers

• The riser card assembly

• The processor air duct

• The protective cover on the front panel board

• The flex circuit cable connection on the SAS/SATA module

• The serial port connection on the bridge board

CAUTION: Before replacing any of the boards on the CG2100 server, you must first take

the server out of service, turn off all peripheral devices connected to the

server, turn off the server by pressing the power button, and unplug the power

cord(s) from the system and wall outlet.

When handling the bridge board, observe the normal safety and ESD precautions. See

Appendix A: Safety Information for more information.

For the location of the cables connected to the bridge board, see Figure 7 and Table
