Operator’s panel
The enclosure’s front panel has an integrated operator’s (Ops) panel with four LEDs. The Ops panel
provides you with a high level indication of the operation of the enclosure. See “Ops panel LEDs”
on page 8 for details of the LED status conditions.
Enclosure replacement should only be performed by trained personnel.
Alarms
Visible alarms
The functional modules have associated status LEDs. The Ops panel shows a consolidated status
for all modules. LEDs show constant green or blue to indicate good or positive status. Constant
or flashing orange LEDs indicate the presence of a fault within that module.
See “Ops panel LEDs” on page 8 for a description of the Ops panel LED states.
Caution
The Ops panel is an integral part of the enclosure assembly and cannot be replaced
separately. To replace the Ops panel, you must replace the entire enclosure.
