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 up 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 will stay powered on. However,
if the cell board is powered off, it will 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 will only be 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 on page 133 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. Refer to
Table 5-13 for details.
