1.3 Visible and Audible Alarms
The functional modules have associated status LEDs. The Ops Panel
shows a consolidated status for all modules.
LEDs show constant green for good or positive indication. Constant
amber LEDs indicate there is a fault present within that module.
The Ops Panel also incorporates an audible alarm to indicate when a
fault state is present and also an Alarm Mute push-button.
1.4 Internal Drive Loop Structure
The EF2800 enclosure is configured with two internal loops of 8 drives.
The 16 drive dual loop internal connection structure is shown in
Figure 12 . Two plug-in, Loop Redundancy Circuit SM modules are
mounted in rear Bays 3 and 4
(Figure 4)
; these contain Port Bypass
Circuits (PBC) that provide loop resiliency in the event of unplugged or
failing drives.
