If you selected Exit EZSwitchSetup, the EZSwitchSetup switch configuration wizard closes.
Switch discovery failure
During the setup of your switch, the switch discovery may fail. There may be several reasons why
switch discovery fails. The following table lists symptoms and related suggestions to recover the switch.
Discovery recovery
TABLE 3
Symptom
Correction
For serial connections:
The setup computer COM port is
busy.
The port is being controlled by another communications program. Stop all
other third-party communications programs.
The port settings are in conflict with another device. Check your IRQ
settings.
On Windows systems:
By default, COM1 and COM3 use IRQ4, while COM2 and COM4 use IRQ3.
If another device is sharing the IRQ of the port, you must change the IRQ of
the conflicting device. Hardware conflicts can also occur with the I/O
address of the COM port. The 8514a video chip or its clones (S3 chip set)
on some video cards create a conflict with COM4 because they use the
same address of 02E8.
The switch does not respond to
commands during a serial
connection.
The serial cable may not be connected properly between the setup
computer and the switch. Check the serial cable to ensure it is secured.
The switch does not power up.
Verify that the switch’s power cable is securely plugged into a proper outlet
and that the switch’s power button is turned on.
The switch’s serial adapter does not
work.
Verify that the cable is good by replacing the cable or trying it on another
known working device.
If the cable is good, then call your support provider for further instructions.
For Ethernet connections:
The WWN is not entered correctly.
Verify that the WWN is correct.
The target switch is not on the same
subnet as the host.
Connect the host to the same subnet as the target switch. If it is not
possible or convenient to do so, use the serial connection to set the IP
address.
The target switch has no IP address
instead of the factory default
10.77.77.77.
Use the serial connection to set the IP address.
