Determining Whether A Component Is Hot-Pluggable; Component Hot-Pluggability - HP 201723-B21 - StorageWorks Modular SAN Array 1000 Hard Drive Maintenance And Service Manual

Determining whether a component is hot-pluggable

Before removing 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 replacement is available before removing a component or blanking panel from the chassis.
Open slots dramatically impact airflow and cooling within the enclosure.
