Management Ports

The following management ports let you configure, monitor, and upgrade the
switch:
■

RS-232 Terminal Port (ASYN0)

Out-of-Band Ethernet Management Port

■
RS-232 Terminal Port (ASYN0)
The RS-232 ASYN0 port is standard for the AT-8900, AT-9900, and AT-9900s
switches, and connects them to a management device for initial configuration.
This port allows the software on the switch to be accessed from a terminal or a
PC running terminal emulation software.
The ASYN0 port has an RJ-45 socket with an industry recognised pinout. This
requires using a straight-through RJ-45 cable with an RJ-45 DB9 connector
when the switch is connected to a terminal or PC. The socket is wired as a DTE
and the pin layout is shown in the following figure and table.
Pin Role
1 RTS
2 DTR (DSR and DTR are connected but have no other internal connection)
3 TXD
4 GND
5 GND
6 RXD
7 DSR (DTR and DSR are connected but have no other internal connection)
8 CTS
Out-of-Band Ethernet Management Port
The out-of-band 10/100/1000 Mbps Ethernet port is dedicated to management
traffic on the AT-9900s switch. Use it for initial configuration and on-going
management tasks. For remote access, use the default IP address,
192.168.242.242. This port is reserved for management only; the switch does
not transmit frames between this port and switch ports.
