Verifying Cell Board Insertion
Cell Board Extraction Levers
It is important that both extraction levers on the cell board be in the locked position. Both levers
must be locked for the cell board to power on and function properly.
Power to the cell board should only be removed using the MP:CM> PE command or by shutting
down the partition or server. Therefore, if the levers become unlocked, the partition will not
have a chance to logically shut down, and damage could occur to the operating system.
If the cell board is powered on and one lever becomes unlocked, the cell board stays powered
on. However, if the cell board is powered off, it does not power on again until both levers are in
the locked position.
The lever status can be determined by issuing the MP:CM> DE command and viewing the power
status of the cell board controller (PDHC). The “ready” bit is only true when both levers are
locked and all VRMs are installed. This status can be used to determine if both levers are locked
and the cell board is properly installed in the chassis. See Figure 5-20 (page 104) for a sample of
the output.
If the state is RDY denoted by capital letters in the computer output then the “ready bit” is
true. If the state is rdy as denoted by lower case letters in the computer output then the “ready
bit” is false. For details, see Table 5-13.
