Replacing the storage expansion node

Use these instructions to attach a replacement storage expansion node to the expansion shelf.
Before you begin
Before you attach the storage expansion node to the expansion shelf, complete the following steps:
1. Read "Safety" on page iii and "Installation guidelines" on page 25.
2. Lay the expansion shelf on a flat, static-protective surface with the black edge facing you.
3. If a compute node is attached to the shelf, remove the compute node cover, if you have not already
done so (see the compute node Installation and Service Guide for instructions).
Procedure
Attention: If a compute node is attached to the shelf, bend the interposer cable up and over the storage
expansion node to ensure that the cable and connector are clear of the compute node.
With the left edge of the storage expansion node aligned with the expansion node alignment mark on the
expansion shelf, orient the slots on the bottom of the storage expansion node with the posts on the right
side of the expansion shelf. Then, slide the storage expansion node toward the center of the shelf until the
retention latch clicks into place, as shown in the following illustration.
What to do next
Complete the following steps:
1. If a compute node is attached to the expansion shelf, complete the following steps:
a. If any I/O expansion adapters in the compute node are blocking access to the interposer connector,
remove them (see the compute node Installation and Service Guide for instructions).
b. Connect the interposer cable to the interposer connector on the compute node system board,
as shown in the following illustration.
