Removing the hard disk drive tray
To remove the hard disk drive tray, complete the following steps.
Note: The following illustration shows how to remove the hard disk drive tray from
the blade server; removing the hard disk drive tray from the MPE unit is similar.
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 63.
2. If the blade server is installed in a BladeCenter unit, remove it (see “Removing
the blade server from a BladeCenter unit” on page 65).
3. Remove the blade server cover (see “Removing the blade server cover” on
page 68).
4. If you are removing the drive tray from the blade server and an MPE unit is
installed, remove the MPE unit (see “Removing an expansion unit” on page 70).
5. Remove the hard disk drive from the drive tray, if one is installed (see
“Removing a SAS hard disk drive” on page 74).
6. Remove the four screws that secure the drive tray to the system board; then, lift
the drive tray out of the blade server.
7. If you are instructed to return the drive tray, follow all packaging instructions,
and use any packaging materials for shipping that are supplied to you.
