Local Management Session
On the front panel of the switch is a port labelled RS232 Terminal Port.
You use this port to establish a local management session with the
switch’s AT-S39 management software.
A local management session is so named because you must be close to
the switch, usually within a few meters, to start this type of management
session. This typically means that you must be in the wiring closet where
the switch is located.
A switch does not need an IP address to be managed from a local
management session. You can start a local management session at any
time on any AT-8024, AT-8024GB, or AT-8026FC switch in your network.
Additionally, running a local management session does not interfere
with the flow of Ethernet traffic through the unit.
Starting a local management session on a switch that has been
configured as a Master switch of an enhanced stack allows you to
manage all the switches in the subnet from the same local management
session. You do not have to start a separate local management session
for each switch. This can simplify network management.
Starting a local management session on a switch that is not part of an
enhanced stack or that is a slave switch in an enhanced stack allows you
to manage just that switch.
