PFR 500/E Instruction Manual
23
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. These connectors are used when NetCentral monitoring software is used.
Refer to your PVS Series Installation Guide or the Media Area Network Instruction
Manual for information how these connectors are used.
The RAID Controller includes rear panel Fibre Channel loop port status LEDs and
other status LEDs. Refer to
“Interpreting rear panel status LEDs” on page 38
.
NOTE: The PFR 500E Expansion chassis and PFR 500 Controller chassis must be
powered on and off in the proper sequence. Refer to proper power procedures in
Chapter 2, “PFR500/E Installation Information”.
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
“Interpreting rear panel status LEDs” on page 38
.
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.
