Placing a 9040-MR9 system into the service position
Use this procedure to place an IBM Power System E950 (9040-MR9) system into the service position.
Before you begin
Attention:
• When you place the system into the service position, it is essential that all stability plates are
firmly in position to prevent the rack from toppling.
• Ensure that only one system unit is in the service position at a time.
• Ensure that the cables at the rear of the system unit do not catch or bind as you pull the system
unit forward in the rack.
• When the rails are fully extended, the rail safety latches lock into place. This action prevents the
system from being pulled out too far.
Procedure
1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged
into a ground jack or connected to an unpainted metal surface. If not, do so now.
2. Label and disconnect all external cables that are attached to the PCIe adapters.
3. If you have not already done so, remove the front cover from the system. For instructions, see
"Removing the front cover from a 9040-MR9 system" on page 48.
4. Complete the following steps to place the system in the service position.
Do not pull out or install any drawer or feature if the rack stabilizer brackets are not attached to the
rack. Do not pull out more than one drawer at a time. The rack might become unstable if you pull out
more than one drawer at a time.
a. If not already removed, remove the shipping screws (A) as shown in the following figure by using a
Phillips screwdriver.
b. Release the side latches (B) by pressing them downward as shown in the following figure.
c. Pull out the system (C) as shown in the following figure. Ensure that any cables do not catch or bind
as you pull out the system.
