"Bypassed" means that the signal for a Fibre Channel loop is low even though the
disk is present. It indicates a disk has received a Loop Port Bypass primitive or
has been removed from the Fibre Channel loop for some reason.
"Loop Failed" means that there is no valid Fibre Channel data present at the input
connector on the port bypass card.

Red (1 intermittent flash) - Disk is bypassed on loop 1
Red (2 intermittent flashes) - Disk is bypassed on loop 2
All 7 Disks Red (1 intermittent flash) - Loop 1 is failed

All 7 Disks Red On - Link has failed on both loops
Off - Disk is operating normally
On - Fault status. Disk may not be responding to con-
