Note: Do not install a SAS hard disk drive in SAS connector 1 (SAS ID 1) if you
intend to also install an optional standard-form-factor expansion card. The
standard-form-factor expansion card occupies the same area as the second
hard disk drive.
To install a SAS hard disk drive, complete the following steps:
1. Read the safety information that begins on page v and "Installation guidelines"
on page 15.
2. Shut down the operating system, turn off the blade server, and remove the
blade server from the BladeCenter unit (see "Removing the blade server from
the BladeCenter unit" on page 17 for instructions).
3. Carefully lay the blade server on a flat, static-protective surface.
4. Open the blade server cover (see "Opening the blade server cover" on page 18
for instructions).
5. If a Memory and I/O Expansion Blade is installed, remove it (see "Removing an
expansion unit" on page 19).
6. Locate SAS connector 0 (J136) or SAS connector 1 (J137).
7. If a standard-form-factor expansion card is installed in the SAS connector 1
location, complete the following steps:
a. Remove the expansion card (see the illustration in "Installing a
standard-form-factor expansion card" on page 31) and its mounting bracket,
and save the screws that secure the mounting bracket to the system board.
Store the screws in a safe place.
b. Install the SAS connector 1 drive tray. Secure the drive tray to the system
board with the screws from the option kit.
Attention: Do not press on the top of the drive. Pressing on the top might
damage the drive.
8. Put the drive into the tray and push it, from the rear edge of the drive, into the
connector until the drive moves past the lever at the back of the tray.
9. If you have other options to install or remove, do so now; otherwise, go to
"Completing the installation" on page 34.
