Management Session Errors

90
This chapter discusses what actions to take if you encounter errors when
establishing a management session and how to correct problems with
the AT-8401 management card, AT-8400 line cards, and power supplies.
This section describes what actions to take if you cannot establish a
management session. Both local and remote management sessions are
discussed.
If a local management session cannot be established, do the following:
❑ Check that the management card is securely seated in the chassis.
❑ Verify that a straight-through RS-232 cable is connected to the
management card.
❑ Check that the RS-232 cable is securely connected to the RS-232
port on the management card and the other end is connected to
a terminal or PC.
❑ Verify the RS-232 cable is a straight-through cable and not a
crossover cable.
❑ Verify that the operating parameters for the terminal or the
terminal emulator program are configured correctly. The default
values for the RS-232 port can be found in the AT-S60
Management Software User's Guide. This guide is available
online at www.alliedtelesyn.com.
If a remote management session cannot be established:
❑ Check that the AT-8401 management card is securely seated in
the chassis.
❑ Verify that an IP address has been assigned to the management
card and you are using the same IP address at the start of the
remote session. Refer to the AT-S60 User's Guide for instructions
on assigning an IP address.
❑ Ping the chassis from a workstation using a PING utility. If a ping
fails, either the chassis is not operating, the physical data path to
the chassis has experienced a failure, or an incorrect IP address
has been entered.
❑ Reset the AT-8401 management card by pressing the Reset
button on the front of the management card.
