cannot remove the second power supply and fan unit (because the
storage subsystem requires that at least one power supply and fan unit,
functioning or not, must be present in the storage subsystem at all
times).
Releasing a component lever
Each component is secured into the storage subsystem chassis by two cam lock
levers mounted to the component. The lever engages with a pin on the storage
subsystem chassis to pull the component securely into the chassis. The levers are
locked in place by spring-loaded latches. The control components have the levers
on the same side. The power supply and fan units and the interconnect-battery unit
have the one lever mounted to the top of the component and one lever mounted to
the bottom of the component. Figure 85 shows a component lever and the latch that
secures the lever. The top view shows the lever in the closed and latched position.
The bottom view shows the lever in the released position.
To release both latches on a component and remove the component, complete the
following:
1. Push the latches to the side until the latches release the levers. Do not proceed
with the next step until you have released both levers from the latches.
2. Rotate both levers out simultaneously. Ensure that the levers are completely
free of the pins. Then place one hand under the component and use the levers
to pull the component from the DS4800 Storage Subsystem.
To
replace a component and lock the latches, complete the following:
