the 4000XA and 4180 faceplate. The AC power cube plugs into the circular connector
labeled 48VDC on the 4284, and the 9480.

Power Over Ethernet
The 4280, 4284, and 9480 will accept power on the LAN connection using the POE
specification. When used, no additional power is required by the device.

Redundant Power
The 4280, 4284, and 9480 may be connected to power on each of their supported
interfaces. For example, the “Power over Ethernet” may be used at the same time as
48V power on the circular connector. The power supplies are isolated from each other
and completely redundant. If one should fail, the other is used without interruption. Note
that the 4280 may be triple redundant with Power over Ethernet, 48V on its 3-prong
interface, and 18-72v on its circular connector.

3.2

ALARM RELAY UNIT INTERFACE

The Alarm Relay Unit connector is a three position (Failed Open, Closed, Failed Closed)
terminal block labeled ALARM on the 4000XA, 4180 or 4280 faceplate. The terminal
block connectors accommodate 10-awg to 14-awg wire.

3.3 CONSOLE

INTERFACE

The console interface is used for initial configuration, and for StarKeeper® II NMS
monitoring on an on-going basis.

This interface requires a standard RJ45-terminated twisted-pair data cable on the
4000XA, 4180, 4280, and 4284. It connects as a data terminating equipment (DTE) to
an asynchronous device and uses RS-232C signaling. It is configured as 9600 bps, 8
bits, no parity and one stop bit.
On the 9480, the serial console interface is available on the secondary port pins of the
DB25 connector (Pins 14 & 16). Once initially configured, all operations may use the
telnet console.

3.4 4180

RS-232/V.11/RS-530SERIAL INTERFACE


The DB25 RS-530 male connector on the 4000XA and 4180 provides support for
software-selectable device interfaces (V.35 and RS232-C) at data rates up to 2Mbps.
The DB25 RS-530 interface is a DTE only. The male connector electrically presents a
data terminal equipment (DTE) interface and supports RS-232C directly. For V.35, a
standard RS-530 DB25 Female to V.35 Winchester-34 Male adapter is available.

The xxxx also provides access to the console function through a TCP telnet

connection via a reserved telnet server port (TCP port 1023). This service is available
only when the unit is in service, and may be protected by Closed User Group
membership.
