Misconfiguring the management VLAN ID.
Note: Be careful not to lock yourself and others out of the IES.
Note: It is highly recommended that you use the
sys reboot < seconds >
command
before using any settings or commands that may lock you out from managing the
device. Use the
sys reboot cancel
command to cancel the scheduled reboot
when you are sure you have the correct configuration. Otherwise, the device will
restart and resume using the settings last saved before using the
sys reboot
command.
28.5 A Line Card Does Not Become Active
A line card is stuck in the inactive state.
It is normal for a line card to be in the inactive state when it is starting up or the firmware is being
upgraded. If neither of these is the case, the line card may be malfunctioning. Try the following.
1
The IES can automatically restart a line card that it is managing. If the line card is unresponsive,
use the
lcman reset
command to perform a hardware reset on the line card.
2
Try removing the line card from the slot and re-installing it.
3
If neither of these steps work, use the
lcman disable
command. Then connect to the line card’s
console port and recover the firmware. The procedure to recover the line card firmware is similar to
the procedure for recovering the IES firmware (see
Section 28.6.2 on page 218 ).
4
After you have recovered the line card’s firmware, use the
lcman enable
command to turn the
IES’s management of the line card back on.
28.6 Resetting the Defaults
You can upload the factory-default configuration file to reset the IES to the default settings. This
means that you will lose all previous configurations and the speed of the console port will be reset
to the default of 115200 bps with 8 data bit, no parity, one stop bit and flow control set to none.
The user name and password will also be reset to “admin” and “1234”. The default in-band IP
address is 192.168.1.1. The default out-of-band IP address is 192.168.0.1.
If you forget your password or cannot access the IES, contact customer support for how to reset
your device to the factory defaults.
28.6.1 Resetting the Defaults Via CLI Command
If you know the password, you can reload the factory-default configuration file via Command Line
Interface (CLI) command. Use the following procedure.
