Stopping a system with the Systems Director Management Console
You can use the IBM Systems Director Management Console (SDMC) user interface to stop the system or
a virtual server.
By default, the managed system is set to power off automatically when you shut down the last running
virtual server on the managed system. If you set the managed system properties on the SDMC so that the
managed system does not power off automatically, you must use this procedure to power off your
managed system.
Attention: If possible, shut down the running virtual servers on the managed system before powering
off the managed system. Powering off the managed system without shutting down the virtual servers
first causes the virtual servers to shut down abnormally and can cause data loss. If you use a Virtual I/O
Server (VIOS) logical partition, ensure that all clients are shut down or that the clients have access to
their devices with an alternate method.
To power off a managed system, you must be a member of one of the following roles:
v Super administrator
v Service representative
v Operator
v Product engineer
Use the following steps to stop the system using the SDMC.
1. In the Power Systems Resource area, select the managed system you want to power off.
2. From the Actions menu, select Operations Power Off.
3. Select the appropriate power-off mode and click OK.
Placing the 8202-E4B or 8205-E6B system into the service or operating
position
Use these procedures to place a system into the service position or operating position to perform service
or to gain access to internal components.
Placing a rack-mounted 8202-E4B or 8205-E6B system into the service position
Use this procedure to place the rack-mounted system into the service position.
Notes:
v When placing 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.
v Ensure that the cables at the back of the system unit do not catch or bind as you pull the unit forward
in the rack.
v When the system unit rails are fully extended, the rail safety latches lock into place. This action
prevents the system from being pulled out too far.
1. Open the front rack door.
2. Identify the system unit you are servicing in the rack.
3. Remove the two screws (A) (if present) that secure the system unit (B) to the rack.
