Chapter 7 Removing and Installing Storage Devices
This chapter describes how to remove and install storage devices and removable media devices. For a list of part numbers for field-replaceable units and optional equipment, see "Illustrated Parts Breakdown".
Tasks covered in this chapter include:
How to Remove the Removable Media Assembly (RMA)
Caution - Removing the removable media assembly activates the system power interlock switches. This safety mechanism prevents all DC voltages (except 5V standby power) from reaching any internal component when the removable media assembly is removed and the front panel keyswitch is left on. Do not remove the removable media assembly while the system is operating or the system will power off abruptly.

How to Remove a Disk Drive
The system's disk "hot-plug" feature lets you remove a disk drive without shutting down the operating system or turning off the system power. For more information, see:
Before You Begin
You must follow antistatic precautions when handling a disk drive. For more information, see:
What to Do
-
Prepare the system for disk removal.
The hot-plug removal procedure involves software commands for preparing the system prior to removing the disk drive. See "About Internal Disk Drives".
Note -If the server is set up without a local graphics console, terminal, or monitor, you need to set up one of these options in order to issue software commands. See "How to Attach an Alphanumeric Terminal", or "How to Configure a Local Graphics Console".
-
If you are not hot-plugging the disk drive, halt the operating system and turn off the system power.
-
Unlock the disk access door and swing it open.
-
Attach the antistatic wrist strap to a metal surface inside the system chassis.
-
Identify the disk drive to be removed and note the bay in which it is installed.
For information about disk status LEDs, see "About Internal Disk Drives".
-
Using your thumb and forefinger, push the drive latch upward to release the drive handle.
Swing the handle out away from the drive until you feel the drive connector disengage from the backplane.
Figure 7-9
-
Holding the drive by the handle, slide it out of the drive bay.
Place the drive on an antistatic mat.
Note -When you reinstall the drive (or a replacement drive), be sure to install it in the same drive bay as the one from which it was just removed.
What Next
If you removed the drive as part of another procedure, complete the other procedure now.

You must follow antistatic precautions when handling a disk drive. For more information, see:
What to Do
-
Prepare the system to receive the new disk drive.
The hot-plug installation procedure involves software commands for preparing the system prior to installing the disk drive. See "About Internal Disk Drives".
Note -If the server is set up without a local graphics console, terminal, or monitor, you need to set up one of these options in order to issue software commands. See "How to Attach an Alphanumeric Terminal", or "How to Configure a Local Graphics Console".

-
Unlock the disk access door and swing it open.
-
Attach the antistatic wrist strap to a metal surface inside the system chassis.
-
Release the drive handle on the disk drive.
Use your thumb and forefinger to pinch the drive latch sideways to open it.
-
Align the disk drive to its drive bay.
Orient the drive so the drive handle's hinge faces the bottom of the drive bay (the left side of the bay in a rackmount configuration).
Note -If you are replacing a drive that you removed previously, be sure to install the drive in the same drive bay as the one you removed.
Figure 7-10
-
Holding the drive by its handle, fit the drive into the guide rails at the top and bottom of the drive bay.
-
Slide the drive into the bay until it barely contacts the backplane.
-
Press carefully on the center of the drive and watch as the handle begins to close.
The drive handle begins to close as the drive engages its backplane connector.
-
Press the handle toward the drive until the latch closes, securing the drive in place.
-
Close the disk access door and lock it if necessary.
-
If you are performing a hot-plug installation, complete the software part of the installation procedure.
What Next
If you have other parts to replace in the system, do so now.
When you are ready to restart the system, be sure to run POST and OpenBoot Diagnostic tests to verify that the system functions correctly with the new parts you have just installed. You must also perform a reconfiguration boot so that your system is able to recognize the new device(s). For additional information, see:
