Solution

DISPATCH INSTRUCTIONS WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED?:

Netra T1 AC200/DC200 product training is desirable but not required

TIME ESTIMATE: 40 mins

TASK COMPLEXITY: 1

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: NVRAM failure

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

If a data backup is not required it is still a wise precaution.

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE?:

Replacing the NVRAM

Caution – The procedure below is for the attention of qualified service engineers only. Before touching or replacing any components inside the Netra T1 server,
disconnect all cables and open the system. Always place the system on a grounded ESD pad and wear a properly grounded antistatic wrist strap.

The NVRAM chip on the Netra T1 server’s system board contains a lithium battery that in time may need replacing. If you see the following message on your console
when you boot the server, you have to replace it:

Warning -- Real-Time-Clock (and NVRAM) battery is low

Caution – There is a danger of explosion if the NVRAM chip is incorrectly replaced. Replace it only with a component of the same type as the used one. To replace the chip, follow any instructions supplied with the new component. Dispose of the used component according to the manufacturer’s instructions.
The NVRAM chip is located in a carrier between the rear fan subassembly and the DIMM sockets on the system board.

1. Make a note of the current settings of the environment parameters diag-switch? and diag-level. You will need these values to carry out Step 5.
To check the setting for diag-switch?, type:

ok printenv diag-switch?

To check the setting for diag-level, type:

ok printenv diag-switch?

2. Open the Netra T1 server. Make sure all external cables are disconnected and pay particular attention to the information about how to prevent electrostatic discharge from your body from damaging the components of the server.

3. Carefully take the NVRAM chip carrier lengthwise between your thumb and forefinger and pull it out of its socket.

4. Holding the new NVRAM chip carrier in a similar fashion between your thumb and forefinger, position it over the socket and press firmly until the connectors
engage.

5. When you have reconnected the cables and powered the server on, type the following at the ok
prompt, using the values you noted in Step 1:

6. Replace the system cover and tighten the captive screw:
ok reset-all
ok setenv diag-switch?   noted_value
ok setenv diag-level    noted_value
ok reset-all

OBTAIN CUSTOMER ACCEPTANCE WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO
RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Boot the system and verify all components are working properly by verifying POST has completed. Logon to root account after booted and running the command # prtdiag ensuring all components present.
