SWITCH DISCOVERY FAILURE
During the setup of your switch, the switch discovery may fail. There may be several reasons why
switch discovery fails. Table 2 lists symptoms and related suggestions to recover the switch:
TABLE 2 Discovery recovery
Symptom Correction
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
need to 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
they are secured.
The switch does not power up. Verify that the switch’s power cable is securely plugged into a
proper outlet and that the switches 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 good working device.
If the cable is good, then call your support provider for further
instructions.
