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.
