DISPATCH INSTRUCTIONS
  WHAT SKILLS DOES THE ENGINEER NEED:  Exadata trained
  TIME ESTIMATE: 120 minutes
  TASK COMPLEXITY: 2

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:
   PROBLEM OVERVIEW:

A Rack PDU is failed and needs replaced.

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

The PDU can be replaced hot, without taking power down to the rack. The 2nd operating PDU will maintain power to all of the units using the redundant power supplies in each server and switch. The only exception is Exadata X2-2 and Big Data Appliance (V1) racks with the Keyboard/Monitor tray (a non-critical item) that is powered only on the PDU-B side.

There are 3 potential risks to the operating rack:
1. From unlatching IB cables in the rack inadvertently. A loss of service in IB may result in nodes being evicted from the cluster which may bring down the rack. Care should be made if having to handle the IB cables, but the risk should be limited as the IB cables should be latched securely and should not unlatch even with significant tension being placed on them from pulling.

2. If the rack is in a raised-floor environment, then it may be necessary to move the rack forward or backward in order to align the PDU plug with the floor tile cutout and rack floor cutout. Cut-outs should have been made large enough per the documentation, however that is not always followed particularly in older data centers. Extra care should be taken to ensure there is sufficient slack for any customer added network cables and multi-racking InfiniBand cables if present. In multi-racked environments, it is highly recommended to disable subnet manager on this rack prior to moving it, to ensure other racks are not impacted inadvertently to unplanned subnet manager failovers. In over-head cabling environments, the top cable pass through panel can be removed if necessary to facilitate passing the outlet plug through it, by undoing the screws that attach it on the top of the rack.

3. If you are replacing a PDU which is still operational, but the display has failed, you must verify all PSU's are functioning for all components in the rack prior to shutting down one of the PDU's.  If any component has a power supply failure on the redundant side not being serviced, that component will go down and could result in a customer outage.  Physically check all servers, as well as IB and Cisco switches to ensure power is available on both power supplies.   

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

Replace the PDU, following the process instructions detailed in MOS Note 1423708.1. The note also has 2 instructional videos attached for the removal and replacement showing how to do it live.

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

Verify the PDU is functioning, and all servers and switches are no longer showing failed for the power supplies. On servers, use the front LED's. On the IB and Cisco switches, look through the vented filler panels to ensure both sides PSU's are green. On the KVM switch on the left side ensure both power LED's for A and B are green. If PDU-B was replaced, verify the Keyboard/Monitor tray comes on if applicable.

On the PDU, verify the current monitor is displaying the current draw on each input and outlet group. Use the button to toggle the direction and input being displayed (on units with more than 1 3-phase input).

From a workstation or laptop on the customer's network, verify the PDU can be accessed over the network to display the current monitor in a web browser. The PDU should be reconfigured for the customer's network, per the detailed instructions in the EIS checklist for the appropriate system. EIS checklists where Enhanced PDU models shipped include instructions for both original and Enhanced PDUs.
