CAUTION:
Only trained service technicians are authorized to remove the enclosure cover and access any of the
components inside the enclosure. Before performing any procedure, see your Product Information Guide for
complete information about safety precautions, working inside the enclosure and protecting against
electrostatic discharge.
NOTICE:
RAID controller modules are hot-pluggable and can be removed and installed without shutting down the
enclosure. However, removing a controller module while data traffic is occurring that involves that controller could
cause data loss and is not recommended. Use the MD Storage Manager to take the RAID controller module off line
before removal.
CAUTION:
Always wear a wrist grounding strap when handling equipment with static-sensitive components.
See your Product Information Guide for safety information.
