Replacing an RTC Battery Inside the SIOC
The battery type inside the SIOC is CR1632.
Step 1 Shut down and remove power from the entire system, as described in Shutting Down and Powering Off
the System, page 3-9 .
Step 2
Remove the SIOC from the system:
a. Loosen the single captive thumbscrew on the SIOC and then open its two hinged ejector levers to
evenly disengage the SIOC from its midplane connector.
b.
Pull the SIOC from the system.
Step 3 Remove the SIOC cover as described in Removing the System I/O Controller Cover, page 3-14 .
Step 4
Gently pry under the battery to lift it from its socket on the SIOC board.
Step 5 Insert the new battery into the socket and then press down until it sits flat.
Step 6
Replace the cover to the SIOC.
Step 7 Replace the SIOC to the system:
Note
If you have only one SIOC, it must be in SIOC bay 1 (see Figure 1-2 on page 1-2 ).
a. Push the SIOC into its bay until it stops against the internal midplane.
b.
Close the two levers on the SIOC to fully engage the SIOC connector with its backplane.

Replace power cords and then power on the system by pressing and holding the power button on the front
handle for four seconds.
