The Rear Panel
Power Connections
The rear panel features two outlet banks. Each bank consists of (1)
AC Input Power Cord
, (1)
Power
Switch/Circuit Breaker
, and (4)
AC Power Outlets
.
Bank 1 provides AC output power to Ports 1 through 4
Bank 2 provides AC output power to Ports 5 through 8
Each
AC Input Power Cord
is outfitted with a NEMA 5-15P plug. Each Bank also has a
15 Amp Power
Switch/Circuit Breaker
that supplies AC power to the bank of four switched outlets and to the internal power
supply. If only one Power Switch/Circuit Breaker is turned on, the internal, redundant power supply will power
the PDU and that one bank will provide AC output. If both banks are off, all outputs will be off.
The four switched AC outlets per bank are NEMA 5-15R, nominal-115VAC power outlets. Bank 1 consists of
Ports/Outlets 1 through 4 and Bank 2 consists of Ports/Outlets 5 through 8
.
Each outlet is independently
controlled and can switch up to 10 Amperes. However,
the total power draw for each bank of 4 outlet ports
must not exceed 15 Amperes
.
Note: The total power draw for each bank of 4 outlet ports must not exceed 15 Amperes
.
The two internal power supplies that are used to power the PDU system are redundant. This feature will allow
the unit to maintain power in the event of a DC Power Supply failure. Upon recovery from a power failure, the
PDU will return all Ports to the same state they were in prior to the power loss.
Status LEDs
The LEDs on the rear panel correspond to each of the (8) Switched AC Outlets. (For example, LED 1 shows
the status of Outlet/Port 1, LED 2 shows the status of Outlet/Port2, etc.) When the status light of an Outlet/Port
is
green
, the Outlet/Port has power.
USB Firmware Upgrade Port
There is a USB-B connector on the rear panel of the PDU for firmware upgrades. Firmware updates are
through a USB cable and an application that runs on a Windows (2000, XP, or Vista) PC.
Please visit
for updates and instructions.
Serial Interface
The PDU 4/4 features (2) RJ45 serial connectors, labeled
CONTROL IN
and
CONTROL OUT
, on the rear
panel. If cascading multiple PDU units, the first PDU will be connected to the controlling terminal using the
CONTROL IN
port. The
CONTROL OUT
port will be connected to the
CONTROL IN
port of the next unit using
a straight-through RJ45 cable, and so on.
