FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: An Oracle Server X7-8 System Module (SMOD) Coin Cell battery needs replacement

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

This is a cold-service component. If the system is still up and functioning, customer should perform an orderly and graceful shutdown of applications and OS. Then power off the server and remove the AC power cords from the system.

A data backup is not a prerequisite but is a wise precaution.

WHAT ACTIONS ARE REQUIRED?:

Oracle Server X7-8 Service Manual

Here are the procedures for accessing and servicing the Real Time Clock system battery, 3V Lithium Coin Cell Battery CR 2032. Perform these procedures to replace a failed system battery (also known as an RTC battery) installed in SMOD0 or SMOD1. This is an internal component accessed from the back of the server by removing the SMOD.

The real-time clock (RTC) battery maintains system time when the server is powered off and a time server is unavailable. If the server fails to maintain the proper time when the system is powered off and not connected to a network, replace the battery.

Caution - Ensure that all power is removed from the server before removing or installing the battery. You must disconnect the power cables from the system before performing this procedure

How to Remove the SMOD Module and the CMOS battery

1. Prepare the server for cold service.

2. Access the rear of the server.

3. Label and disconnect all cables from the SMOD (SMOD0 or SMOD1) you are replacing the Coin Cell Battery in.

4. Disengage the SMOD (SMOD0 or SMOD1) from the server midplane.

A. To Unlock the SMOD handles, squeeze together the release latches on the end of both handles. The unlocking action is accompanied by an audible click.

B. To disengage the SMOD from the server midplane, simultaneously, rotate both handles downward toward their fully open positions. This action disengages the connectors on the SMOD from the connectors on the server midplane.

Caution - Physical harm or component damage. Do not use the SMOD handles to remove the SMOD from the server.

6. To remove the SMOD (SMOD0 or SMOD1), hold the SMOD by it's sides and slide it out of the server.

Caution - The SMOD is heavy. Be prepared to hold it firmly when it is clear of the slot.

7. Set the SMOD (SMOD0 or SMOD1) on a flat surface with the back side facing toward you. The coin cell battery is located on the SMOD motherboard on the right side below the disk backplane in a vertical holder.

8. To remove the battery, pull it up and out of its holder by tilting the battery out, away from wall, and then lift the battery up.

How to Install the replacement Coin Cell battery

1. To orient the replacement battery, ensure that the positive (+) side of the battery is facing toward the inside of the SMOD.
Make sure the positive pole (+) is facing toward the inside of the SMOD.

2. Press the new battery into the battery retainer.
To install the battery, set it in the holder and push it in until the battery snaps into place.

Note - If disconnected during battery removal, reconnect the auxiliary signal cable to the disk backplane and the SAS cables to the Internal HBA.

3. Ensure that the battery is properly seated in its holder and the polarity is correct.

4. Install the SMOD (SMOD0 or SMOD1) by following the procedure below.

How to Install the SMOD Module

1. Ensure that the handles on the SMOD (SMOD0 or SMOD1) are in their fully open position.

A. To Unlock the SMOD handles, squeeze together the release latches on the end of both handles. The unlocking action is accompanied by an audible click.

B. To open, rotate both handles downward until they are at a 90 degree angle to the SMOD (fully open position).

2. Orient the SMOD with the handles facing away from the server and the connectors facing toward the open slot in the server.

Caution - Physical harm or component damage. Do not use the SMOD handles to insert the SMOD into the server.

3. Align the SMOD in the slot.

4. Slide the SMOD into the slot until it stops. This leaves the SMOD protruding slightly from the back of the server. Do not attempt push the SMOD in beyond this point.

5. To install the SMOD, simultaneously rotate both handles upward until they lock into place. This action draws the SMOD inward engaging the SMOD connectors with the connectors on the server midplane.

Caution - Pinch point. When operating the lever, keep your fingers clear of the back side and hinged end of the lever.

6. Connect the external cables to the SMOD (SMOD0 or SMOD1).

7. Make sure the time and date are set correctly.

Once the ILOM has fully booted login to the ILOM and set the time and date.
Cd to SP/clock and update the time and date with the set command.

WHAT ACTIONS ARE REQUIRED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE?:

Boot up system and verify full functionality

How to verify the SMOD and Service Processor work properly.

Connect and try to access the SP via SER MGT port or after some time the SP IP address, if DHCP is available.

If the SP login is accessible, then check system status.
