PFR 500/E Instruction Manual
16 October 2001
When the redundant Fiber Channel option is not installed, only one RAID Controller
is installed along with one LBB module as shown in the following figure. The LBB
module and the LBB contained in the RAID Controller module provide the two LBBs
required in the PFR500 Fibre Channel RAID Storage Chassis. The LBB and RAID
Controller modules are clearly labeled on the rear panel of each canister.
The RAID Controller is equipped with a passive 9-pin copper GBIC installed as the
Fibre Channel host port. The RAID Controller also has a Fibre Channel loop
expansion port which extends the internal Fibre Channel Loop to the corresponding
Loop Bypass Board in a PFR500E Expansion Chassis.
An RJ-type connector is provided for Ethernet network connection. A DB-9 serial
communications connector is provided for serial communications with a console
program. Neither of these connectors are used in Grass Valley Group storage systems.
The RAID Controller includes rear panel Fibre Channel loop port status LEDs and
other activity LEDs. Refer to
“Monitoring PFR 500/E status” on page 36
.
Power supplies
There are two auto-ranging power supplies, each with its own power cord and standby
switch. Each supply supports a fully configured PFR500 and shares load currents with
the other supply, if it is present. The power supplies are designed so as to protect the
disk drives if you install them while the PFR 500/E is powered up. A disk with
power-related faults will not adversely affect the operation of any other disk.
Each power supply has status LEDs visible from the rear panel. The status LEDs are
described in the
“Monitoring PFR 500/E status” on page 36
.
A retaining screw secures the power supply in place. You can add or remove one
power supply in the PFR500/E while the PFR500/E is powered up.
