2: Storage Enclosures
Overview
Important: Several references are made in this chapter to the storage management
software (TPSSM). For complete information on the operation and use of this software,

Figure 2-1 shows a front view of the storage enclosure. The front of the enclosure
contains the following components:
• Front bezel: The bezel is a removable decorative cover with holes for viewing the
status LEDs and openings for the drive bays.
• Disk drives: Up to 14 sled-mounted drives can be installed in the bays on the front
of the enclosure.
• LEDs: There are two LEDs for each of the 14 drive bays that indicate the status of
the drive: the drive active LED and the drive fault LED. There are also two LEDs
that indicate the status of the entire enclosure: the enclosure fault LED and the
enclosure power LED.
• Alarm mute button: This button silences the audible alarm of the controller
enclosure. The expansion enclosure does not have an alarm; therefore, the
expansion enclosure does not use this button.
Note: Controller enclosures and expansion controllers look identical when viewed from
the front.
