Removing a drive on module from the 8001-12C or 8005-12N system
Learn how to remove a drive on module (DOM) from the IBM Power System S821LC (8001-12C) or the
IBM CS821 (8005-12N) system.
Before you begin
Locate the drive. Ensure that the media device is unmounted from the Linux system and if needed,
remove the media from the device. Use these commands: “mvCLI commands” on page 74.
Power off the system and place it in the service position. For instructions, see “Preparing the 8001-12C or
8005-12N system to remove and replace internal parts” on page 70.
Procedure
1. Attach the electrostatic discharge (ESD) wrist strap.
Attention:
v Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack, or to
an unpainted metal surface of your hardware to prevent the electrostatic discharge from damaging
your hardware.
v When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is
used for static control. It does not increase or decrease your risk of receiving electric shock when
using or working on electrical equipment.
v If you do not have an ESD wrist strap, just prior to removing the product from ESD packaging and
installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of
5 seconds.
2. Remove the DOM from the system backplane as shown in Figure 9.
