Determining wh

ether a component is hot-pluggable

Before removin

g any serviceable part, determine whether the part is hot-pluggable or non-hot-pluggable.

• If the component is hot-pluggable, a power shutdown of the device is not required for replacement

of the part.

• If the component is not hot-pluggable, the device must be powered down.

CAUTION:

Be sure the rep

lacement is available before removing a component or blanking panel from the chassis.

Open slots dr

amatically impact airﬂow and cooling within the enclosure.
