FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: A Sun Fire X4500 Coin Cell Battery needs replacement

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

As usual, the best is when customer shuts down the OS.
Also in case we need to rack out the server, as usual, write down to a paper sheet a complete wiring diagram.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:1. Power off the server

2. Remove the cable management arm.

See one of the following depending on your system:

Sun Cable Management Assembly Installation Guide for the Sun Fire X4540 Server
Sun X4500-J Slide Rail Installation Guide (X4500)
Early-Production Slide Rail and CMA Information (X4500)
3. Remove the system controller

4. Remove the battery by gently pulling the clip away from the battery face and lifting the battery straight up

Note: Observe the orientation (polarity) of the battery in its holder before it is removed. The positive polarity, marked with a "+" symbol, must face toward the side where the PCI slots are located.

5. To install a new battery, gently pull the clip away and insert.

Note: Install the new battery in the holder with the same orientation (polarity) as the battery that you removed.

6. In some cases for the battery to work, you might need to reset the CMOS on the I/O controller board.

To reset the CMOS, use a screwdriver to short the pins for one or two seconds on jumper J27 on the I/O controller board. Jumper J27 is near the serial connection to the service processor (labeled SER MGT) on the back of the server.
