How to Replace an NMS (Netra Modular System) X5-2M compute node

Solution

CAP PROBLEM OVERVIEW:

The modular system is designed for the components such as the nodes to be line-replaceable items, meaning that instead of servicing the nodes, you return the
nodes to Oracle and receive replacements.  The only individual components that can be serviced inside the x5-2M are:  DIMMs, FANs, Disks, and the coin battery.

Note – You cannot service a node while it is in the modular system. The system’s design differs from other racks and frames that allow you to partially remove a node for service.

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:
Netra Modular System Training
Oracle Server X5-2 Training.

TIME ESTIMATE: 15 minutes

TASK COMPLEXITY: 2

FIELD ENGINEER INSTRUCTIONS

It is recommended before arriving on site to review the process in the service manual supplement as it contains graphic and additional information that is too large or too complex to fix into this text only CAP.

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

Remove a Node

1. If the node is configured as an ASR asset, deactivate it.

2. Follow the safety precautions provided in the “Preparing for Service” topic at: http://docs.oracle.com/cd/E41059_01/html/E48312/napsm.z4000019165586.html#scrolltoc

3. Prepare an antistatic surface on a workbench where you will place the node.

4. Arrange for an assistant to help you remove and carry the node to a workbench.

Caution – You must completely remove the node. The modular system rails do not support partial removal and service. Partially removing a node and letting it hang in the rails can damage the rails and possibly the node.

5. Take the node offline:
a. Stop all applications that are running or schedule to run within the service period.
b. If the node is not responding, remove it from the modular system without powering it down.
c. If the node is responding, gracefully power down the node by pressing and quickly releasing the Power button on the front panel.

6. When the amber Service LED is solid, begin the removal process:
a. Loosen the two thumb screws on the node’s front rails.

Caution – Be careful to avoid pinching your fingers with the D-shaped metal handles in the next step.

b. Using the D-shaped metal handles, pull the node straight toward you about three inches to disconnect the backplane connectors.
c. Using two persons, pull it out of the rack with each person holding one side.

Caution – Ensure that both persons support the front and rear of the node from underneath to prevent damage to it.

d. Place the node on a workbench that has an antistatic surface large enough for the entire node.
e. If you are servicing an internal FRU, perform the service.

7. When the service is completed, reinstall the node.  If this is an LRU replacement, install the new node.

Install a Node

1. Follow the safety precautions provided in “Preparing for Service” topic at: http://docs.oracle.com/cd/E41059_01/html/E48312/napsm.z4000019165586.html#scrolltoc

2. Verify you have the correct node configuration for your modular system.

Two node configurations, based on the switch configuration for your system, are available. See “Switch and Node Configurations” on page 72.

3. Arrange for an assistant to help you carry and install the node.

Caution – Ensure that both persons support the front and rear of the node from underneath to prevent damage to it.

4. Using two persons, align the node with the slot that you want to insert it into.

5. Carefully engage the node with the rails on each side of the system, then slowly push the node straight forward, completely into the system. The mating backplane connectors engage. The green OK LED begins to flash, indicating power-up sequence has started. When the green OK LED is solid, the node is initialized and ready for installing and updating software.

6. Tighten the two thumb screws on the node’s front rails.

7. Activate the node if it is an ASR asset.

8. If the node installed is a replacement for a faulty node, use the same packaging to ship the faulty node to Oracle.

9. Install and update the software.
