 Netra 240 - How to Remove and Replace Netra 240 Power Supply

Fix

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

Netra 240 product training is desirable but not required, as the part is a CRU

TIME ESTIMATE: 30

TASK COMPLEXITY: 0

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: Fault Power Supply

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

The Netra 240 server has dual redundant power supplies. You can hot-swap one power supply while the other is still running, without having to power off the server.

For a redundant power supply configuration, the customer should take normal precautions to backup data and notify users of the maintenance, but the system does not need to be shut down.

For a single power supply configuration, the customer should take normal precautions to backup data, notify users of the maintenance and that the system will be powered down. The customer should conduct an orderly software system shutdown.

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

Caution - The power supplies contain pinch points. Be very careful when opening and closing the levers on the power supplies. Keep your hands and fingers away from the base and sides of the levers. For more information about these pinch points, refer to the power supply labels.

Removing a Power Supply:

If this is a Cold Replacement (system powered down), then please skip to Step 2.

If this is a Hot Plug Replacement (system and OS powered on), then follow from Step 1.

1. Type following ALOM command:

sc> removefru PS# (where # corresponds to the PSU to be replaced)

(For example, to replace power supply unit 1, you would enter: sc> removefru -y PS1)

 - When the blue OK to Remove LED on the back of the power supply unit lights up, you can safely remove the unit.

2. Take appropriate ESD procedures

3. Identify power supply to be removed

4. Disconnect the power input cable from the power supply unit being replaced.

Caution - Do not remove the power input cable from the remaining power supply unit. Doing so causes the system to go through an immediate ungraceful shutdown.

4. Pull the lever on the back of the power supply unit down.

 - This disconnects the power supply unit from the power distribution board inside the server.

5. Slide the power supply unit out of the server chassis by pulling on the lever

Installing a Power Supply:

1. Insert the power supply unit in the power supply unit bay.

2. Slide the power supply unit into the server until you feel it engage with the power distribution board inside.

 - Ensure that the lever does not return to a vertical position until the power supply unit engages with the power distribution board. If the lever is vertical, the power supply unit does not engage correctly.

3. Press the lever up until it clicks.

 - Returning the lever to a vertical position engages the power supply unit with the power distribution board inside the server.

4. Use the power supply unit LED indicators to verify that the power supply unit is up and running.

 - The green LED on the back of the power supply unit should light up, indicating that the power supply unit is functioning properly. If the green LED on the back of the power supply unit does not light up, repeat Steps 1-4.

Note: For systems with older ALOM firmware (prior revision 1.5.4), the replacement power supply must be enabled with ALOM command: sc>poweron PS# where # corresponds to the power supply that was replaced.

Only perfrom the next step if this was a Hot Plug replacement/install:

5. At the ALOM prompt, type:

sc> poweron PS# (where # corresponds to the PSU to be installed)

(For example, to install power supply unit 1, you would enter: sc> poweron PS1)

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

If the replacement was a hot swap/plug on a redundant configuration, the system should be operational and need no further work.
If the replacement was in a system with a single power supply, restart software applications per applicable administration guides to resume system operation
