Starting a Telnet Management Session
To start a Telnet management session, specify the IP address of the AT-
8300 Series stack with a Telnet utility. You then enter the Omega
password, if one has been assigned, after which the Omega Main Menu
is displayed, as shown in Figure 1 on page 20. For instructions on using
the Telnet utility, refer to the documentation included with the utility.
Note
An AT-8300 Series stack must have an IP address and subnet mask
for you to be able to manage it using a Telnet utility. Initially
assigning an IP address to a stack can only be performed from a local
Omega management session. If you have just install the stack and
have yet to assign it an IP address and subnet mask, start a local
management session with the stack as explained earlier in this
chapter and then assign it an IP address by performing the
procedure Configuring IP Parameters on page 38 in Chapter 2.
For non-IP environments, you can use the MAC address assigned to the
master switch to connect to the stack, as long as there are no routers
between the management station and the stack. The MAC address is
printed on a label on the front panel of the switch.
It is important to note that you can have only one Telnet session
operating at any one time. The session can be either inbound or
outbound. If you have an inbound session to Omega, you do not have
the option of starting a new session (outbound connection). Therefore, if
you are already using Telnet, the Omega menu selection Connect to a
remote system will not be available (described in detail in Connecting to
a Remote Stack on page 31). In addition, a local RS232 connection
blocks a Telnet session and vice versa.
If you are currently in a Telnet session, you must disconnect Telnet after
quitting Omega. Otherwise, future Telnet or local sessions to the
multiplexer will be blocked. You can configure a timeout value so that
the management module automatically disconnects a management
session after a period of inactivity, as explained in Specifying a Timeout
Value on page 128 in Chapter 7.
Note
For a description of the Omega main menu, refer to the section
Omega Main Menu on page 20.
