Removing the front LED card

Use these instructions to remove the front LED card from the Flex System Enterprise Chassis. The front LED card must be replaced when it is determined that the card is no longer functioning.

Before you remove the front LED card, complete the following tasks:

1. Shut down the compute node operating system; then, shut down the compute node. See the documentation that comes with your compute nodes for the procedure to shut down the operating system.
2. Shut down the management node, if one is installed. See the Flex System Manager Installation and Service Guide for instructions.
3. Disconnect the chassis from power (see Disconnecting the chassis from power).

Note

When you remove the compute nodes, make a note of the bay number for each compute node that you remove. Reinstalling a compute node into a different bay from the one from which it was removed can have unintended consequences. Some configuration information and update options are established according to bay number.

To remove the front LED card, complete the following steps:

1. Remove the compute nodes from node bays 1 through 8 (see Removing a 1-bay compute node or Removing a 2-bay compute node, depending on the compute node installed).
2. Remove the management node, if one is installed in node bays 1 through 8 (see Removing a Flex System Manager management node for instructions).
3. Remove the four chassis shelves from the bottom of the chassis, if any are installed. For each shelf, grasp the shelf next to the blue touch-point tabs and slide the tabs inward toward each other; then, slide the shelf out of the chassis.
4. Remove the two T-8 Torx screws that secure the card to the chassis, using a Torx driver.
   
   
   
5. Slide the front panel LED card access cover back and to the right and disconnect the cable from the card.
   
   
   
6. Remove the front LED card from the chassis and place it on a flat, static-protective surface.
