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 T8-1 System Battery Replacement

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

Note:

If the system is still up and functioning, the Customer should perform an orderly and graceful shutdown of the applications and operating system.
Then power off the server and remove the AC power cords from the system. For ALL scenarios where an AC power down or AC power cycle is required for a T8-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?:

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.

Prepare Host for System Battery Replacement

1. Prepare the server for service.

a. Power off the server and disconnect the power cords from the power supplies.
b. Extend the server to the maintenance position in the rack.
c. Attach an anti-static wrist strap.

2. Check the HOST_AUTO_POWER_ON property:

-> show /SP/policy HOST_AUTO_POWER_ON
Properties:
HOST_AUTO_POWER_ON = enabled

3. If enabled, set the HOST_AUTO_POWER_ON property to disabled:

-> set /SP/policy HOST_AUTO_POWER_ON=disabled

4. Check the NTP policy for the /SP/clock:

-> show /SP/clock usentpserver
Properties:
usentpserver = enabled

5. If enabled, set the property to disabled:

-> set /SP/clock usentpserver=disabled

Replace the System Battery

1. Remove the Top Cover of system

2. Open the clear plastic air duct assembly cover by lifting the edge of the cover closest to the rear of the server. The cover can stand in its upright position but perform the next steps if you need to remove the cover:

a. Open the fan cover.
b. Pull open the plastic tabs to release the clear plastic air duct assembly covers hinged edge and remove it from the server.

3. If a PCIe card is in slot 6, remove it to improve access to the battery.

4. Remove the battery from the battery holder by grasping the battery (with you index finger and thumb) and tilting it to the center of the chassis about a 45 degree angle and lifting the battery up and out of the battery holder.

5. Insert the new battery into the battery holder (with the positive side (+) facing away from the metal tab that holds it in place) at a 45 degree angle and push toward the outer chassis wall to snap into place.

6. If you needed to remove a PCIe card from slot 6, replace that card.

7. Close the clear plastic air duct assembly cover by rotating it down over the motherboard / two memory risers and then slightly pressing in the two tabs to secure it. See following if you need to reattach the cover:

a. Open the fan cover.
    b. Align the clear plastic air duct assembly cover on its hinge edge.
    c. Attach the hinged plastic tabs to the server by pulling them open and letting them seat into the holes so that the clear plastic air duct assembly cover can hinge up and down.
    d. Lower the clear plastic air duct assembly cover (making sure the two pairs of side tabs clear the sides of the server).

8. Install the top cover on the system

9. Return the Server to operation.

    a. Remove any anti-static measures that were used.
    b. Return the server to it's normal operating position within the rack.
    c. 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.

10. 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.

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

The following example sets the date to August 22, 2016, and the timezone to EDT:

-> set /SP/clock datetime=081221302016 timezone=EDT
Set 'datetime' to '081221302016'
set 'timezone' to 'EDT'

-> show -d properties /SP/clock
Properties
datetime = Mon Aug 22 13:20:16 2016
timezone = EDT (EST5EDT)
uptime = 2 days 19:56:49
usentpserver = disabled

12. If the SP policy HOST_POWER_ON was disabled before you replaced the battery, you must re-enable it:

-> set /SP/policy HOST_POWER_ON=enabled

13. If the /SP/clock usentpserver property was disabled before you replaced the battery, you must re-enable it.

-> set /SP/clock usentpserver=enabled

Verify the System Battery

1. Run show /SYS/MB/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
/SYS/MB/BAT

Targets:

Properties:
type = Battery
ipmi_name = MB/BAT
fault_state = OK
clear_fault_action = (none)

Commands:
cd
set
show

->

-> show /SYS/MB/SPM/V_VBAT

/SYS/MB/SPM/V_VBAT
Targets:

Properties:
type = Voltage
ipmi_name = MB/SPM/V_VBAT
class = Threshold Sensor
value = 3.131 Volts
upper_nonrecov_threshold = N/A
upper_critical_threshold = N/A
upper_noncritical_threshold = N/A
lower_noncritical_threshold = 2.744 Volts
lower_critical_threshold = N/A
lower_nonrecov_threshold = N/A
alarm_status = cleared

Commands:
cd
show

2. 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:

Run the Solaris "fmadm faulty" and SP/ILOM "show faulty" command to verify that the fault has been cleared.
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
Restart software applications per applicable administration guides to resume system operation.
