Removing the front adapter-retention bracket
To remove the front adapter-retention bracket, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 95.
2. Turn off the server and all attached devices; then, disconnect all power cords
and external cables.
3. Unlock and remove the side cover (see “Removing the side cover” on page
100).
4. Open the front and rear adapter-retention brackets.
5. Remove all adapters and place them on a static-protective surface.
Note: You might find it helpful to note where each adapter is installed before
removing the adapters.
6. Grasp one side of the bracket at a hinge point and pull outward (while rotating
the bracket slightly toward the rear of the server) until the hinge pin on the
bracket is free of the hole; then, push the bracket in the opposite direction to
release the other side of the bracket and remove the adapter retention bracket
from the server.
