Domestic
Each AC Input Power Cord is outfitted with a NEMA 5-15P plug for all US/Domestic orders. Each
Bank also has a 15 Amp Power Switch/Circuit Breaker that supplies the AC power to the bank of
four switched outlets and one internal power supply. If either Power Switch/Circuit Breaker is
turned on, one of the internal redundant power supplies will power the PDU and the applicable
bank will be available to provide power. If both banks are off, the PDU will not function and all
outputs will be off.
The four Switched AC Outlets per Bank consist of 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 Ports/Outlets 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 an unlikely event of a DC Power Supply failure.
Upon recovery from a power failure to the PDU, the unit will switch the Ports to the same state
they were in prior to the PDU losing power.
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 a Outlet/Port is lit green, the Outlet/Port has power.
USB Firmware Upgrade Port
A USB-B connector is provided on the rear panel of the PDU for easy firmware upgrades.
Firmware updates are possible via a USB cable and an application that runs on a Windows (2000,
XP, or Vista) PC.

instructions.
Serial Interface
The PDU has (2) RJ45 serial connectors on the rear panel:
CONTROL IN
and
CONTROL OUT
.
If using a single PDU, connection to the
CONTROL IN
port is required. The
CONTROL IN
port is
used to connect to a Logical Solutions Secure Console Server or a serial terminal.
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.
