Cmos/Clock Lithium Battery - Intergraph Zx10 5U System Manual

To install a new system board:
WARNING The system is always on when connected to AC power. Before performing this
task, disconnect the system's power cord from its AC power outlet.
1. Connect the power switch/LED cable to connector J24 before installing the new system board.
2. Place the new system board into the base unit front edge first, and then lower the back edge
into the base unit. Slide the system board toward the back of the base unit until all mounting
holes are aligned with their standoffs.
3. Secure the new system board to the base unit using the 13 screws removed previously.
4. Secure the processor retention clips to the system board with the nuts removed previously.
5. Replace the DIMMs, the processors, and the processor bus terminator (if needed) in the
appropriate sockets.
6. Replace the expansion cards in the appropriate expansion card sockets.
7. Reconnect the remaining cables to the system board.
8. Replace the top cover. See Chapter 7, "Gaining Access to System Components."

CMOS/Clock Lithium Battery

The CMOS/clock lithium battery is
located at the bottom of the system board,
next to the lowest expansion card slots.
The battery may be hidden under installed
expansion cards.
If you must replace the battery, the system
will lose its operating parameters stored in
CMOS memory. As a result, the system
BIOS parameter settings are lost. After
you replace the battery, you must reset the
date and time and reconfigure the BIOS.
See the System Board Manual for detailed information on replacing the battery and on using BIOS
Setup to configure the BIOS.
