ESD Caution:

Circuit boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.
Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.

Contamination Caution:

Dust particles of packaging material are number one cause of datacenter contamination. Make sure to remove all packaging material, up to the ESD safe packaging material, while still being outside the datacenter.

PROBLEM OVERVIEW: SPARC T7-4 System Battery Replacement

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

DAMAGE ALERT: Perform a visual inspection of the replacement part to make sure that there are no damaged components, connectors, bent pins, damaged packages during shipping, etc. If the part is damaged, don't install it into the system, order a new part. Handle with caution and package carefully the return part to avoid any damages during shipping.

If the system is still up and functioning, the 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.

NOTE: For ALL scenarios where an AC power down or AC power cycle is required for a T7-x server, please always use the steps in doc 1571054.1 prior to physically removing AC power cables from the server.

WHAT ACTIONS ARE REQUIRED?:

Note - A customer can perform this procedure. The server must be completely powered down before performing this procedure.

Replace the System Battery

1. Prepare the server for service.

a. Power off the server and disconnect the power cords from the power supplies.
b. Attach an anti-static wrist strap.

2. Slide the main module motherboard out of the server.

3. Remove the cover from the main module motherboard and locate the system battery.

4. Push the top edge of the battery against the spring and lift it out of the carrier.

5. Insert the new system battery in the main module motherboard, with the positive side (+) facing out and place the cover back on the main module motherboard.

6. Install the main module motherboard back into the server.

7. Return the Server to operation.

a. Remove any anti-static measures that were used.
b. Re-install the AC power cords and any data cables that were removed.

Note - If the SP is configured to synchronize with a network time server using NTP, the Oracle ILOM clock will be reset as soon as the server is powered on and connected to the network. Otherwise, proceed to the next step.

8. If the SP is not configured to use NTP, you must reset the Oracle ILOM clock using the Oracle ILOM CLI or the web interface. For instructions, see below or the Oracle ILOM documentation.

9. Use the ILOM clock command to set the day and time.

The following example sets the date to November 17, 2012, and the timezone to PDT:

-> set /SP/clock datetime=111716192012 timezone=PDT
Set ’datetime’ to ’111716192012’
Set ’timezone’ to ’PDT’

-> show -d properties /SP/clock
/SP/clock
Properties:
datetime = Fri NOV 17 16:19:56 2012
timezone = PDT (PDT)
usentpserver = (none)
Commands:
cd
set
show

Note - For additional details about setting the Oracle ILOM clock, refer to the CLI Procedures Guide for Oracle ILOM.

Verify the System Battery

1. Run show /SYS/MB/V_BAT to check the status of the system battery.

In the output, the /SYS/MB/BAT status should be OK, as in the following example:

-> show /SYS/MB/BAT
Targets:
Properties:
type = Battery
ipmi_name = MB/BAT
class = Threshold Sensor
value = 3.140 Volts
upper_nonrecov_threshold = N/A
upper_critical_threshold = N/A
upper_noncritical_threshold = N/A
lower_noncritical_threshold = 2.704 Volts
lower_critical_threshold = N/A
lower_nonrecov_threshold = N/A
alarm_status = cleared
Commands:
cd
show

2. Verify that the value in the value column shows a voltage of 2.8V or more.

3. Power on server. Verify that the Power/OK indicator led lights steady on.

OBTAIN CUSTOMER ACCEPTANCE

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

Boot system and monitor boot sequence for errors. Test functionality of system:
1. Run the Solaris "fmadm faulty" and SP/ILOM "show faulty" command to verify that the fault has been cleared.
2. Perform one of the following tasks based on your verification results:
   * If the previous steps did not clear the fault, refer to doc 1004229.1 for information about the tools and methods you can use to diagnose and clear
     component faults.
   * If the previous steps indicate that no faults have been detected, the component has been replaced successfully. No further action is required
3. Restart software applications per applicable administration guides to resume system operation.
