Patch 54266-01

C613-10417-00 Rev A

Main system

Main features of the AR440S routers are:

■

300 MHz RISC processor.

■

64 MBytes of SDRAM.

■

16 MBytes of flash memory (1 MByte reserved for boot block code).

■

5 x 10/100 Mbps full duplex, Layer 2 switched Ethernet LAN ports. All

LAN ports have Auto-MDI, however if Auto-MDI is turned off, then all

ports are hardwired as MDI-X. Software can also force a port to either MDI

or MDI-X. 802.1Q tagged VLANs are supported.

■

1 x ADSL Annex B port

■

1 x asynchronous DTE port.

■

Universal AC power supply.

■

On-board hardware encryption processor for DES, 3DES and AES.

Some encryption options may require feature licenses.

The RS-232 asynchronous serial port (ASYN 0) has a DB9 male connector, is

wired as a DTE port and can be used as a general purpose port for terminals,

printers or modems. The default communications settings are:

•

9600 bps

•

8 data bits

•

1 stop bit

•

no parity

•

hardware flow control

ADSL Interfaces

The ADSL port has an RJ11 connector, and supports Dying Gasp.

Power supply

The routers have a universal AC input connector and a power switch on their

rear panel. The routers require a power input of 100-240 VAC and 50–60Hz.

Some interfaces that may be installed in the router are not transformer isolated.

This means they will be referenced to the frame ground of the equipment and

may be damaged if connected to an interface on another piece of equipment

which is at a different ground potential.

Reference on the Documentation and Tools CD-ROM.
