Product Description

1-6

If this additional delay is not applied, the switch attempts to transmit

on an overloaded network, increasing the number of unsuccessful

transmission attempts.

For detailed information concerning software and management

features, refer to the

AT- S20 User’s Guide

Mirror Port

The switch has a dedicated Mirror port. Administrators can use the

Omega software to configure the Mirror port and modes. The Mirror

port can monitor traffic on any port, one port at a time. A protocol

analyzer or an RMON probe can be connected to the port mirroring

connector using a standard Category 5 UTP cable.

In full-duplex mode the user needs to determine if they want to

monitor TX or only RX data, but in only one direction at a time. In

half-duplex mode, both RX/TX can be monitored simultaneously.

Media Dependent

Adapters (MDAs)

The MDAs come in four versions, the AT-A10 which is the

10/100Base-TX adapter, the AT-A11 which is the 100Base-FX/SC

version, the AT-A20 which is the 100Base-FX/MT version and the

AT-A21 which is the 100Base-FX/VF version. The adapter LEDs, one

for Activity and the other for Link status, are located on the switch’s

front panel under Port Activity.
