Discovery recovery
The setup computer COM port is busy.
The switch does not respond to
commands during a serial connection.
The switch does not power up.
The switch's serial adapter does not
work.
The WWN is not entered correctly.
The target switch is not on the same
subnet as the host.
The target switch has no IP address
instead of the factory default
10.77.77.77.
You have requested automatic address
assignment in an environment where a
DHCP server is not available.
lists symptoms and related suggestions to recover the switch.
Correction
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 serial cable may not be connected properly between the
setup computer and the switch. Check the serial cable to ensure
it is secured.
Verify that the switch's power cable is securely plugged into a
proper outlet and that the switch's power button is turned on.
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.
Verify that the WWN is correct.
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.
Use the serial connection to set the IP address.
Use the serial connection to set a reachable address.
