Troubleshooting the PowerConnect B-DCX-4S
Issue
Entire chassis powers off
automatically.
Several or all components are not
operating.
Serial connection is faulty or serial
port logs have incorrect or missing
information.
CP Ethernet link speed is different
than expected or a link cannot be
established.
Configuration data is inaccurate or
cannot be accessed.
Initial set up results in IP
address/Domain ID conflict.
108
provides a list of issues, possible causes, and recommended actions.
Possible cause
Power supplies are inadequate to support the
installed components.
One or both power cables may not be
connected to a live source.
One or both AC power switches might be off.
Serial cable is not connected correctly.
Terminal emulator application parameters
are not set correctly.
Serial port might be incompatible (only
RS-232 is supported).
Pins on the serial cable or serial port might be
damaged.
There might be a conflict with the CP Ethernet
link speed negotiation set up by the network.
Chassis was powered off/on while a WWN
card was uninstalled or failed.
The PowerConnect B-DCX-4S was rebooted
while a WWN card was uninstalled or failed.
The PowerConnect B-DCX-4S was connected
to the fabric before being configured.
Recommended action
Add an additional power supply.
Ensure that both power cables are connected to live
outlets.
Ensure that both AC power switches are on (AC
switches light up green when on).
Ensure that the cable is firmly connected to the
workstation computer and to the PowerConnect
B-DCX-4S.
Ensure that the terminal emulator application is
configured as follows: 9600 bits per second, 8
databits, no parity, 1 stop bit, no flow control.
Ensure that the PowerConnect B-DCX-4S is
connected to an RS-232 port. RS-423 serial ports
might experience difficulties due to corner-case
incompatibilities of the standards.
Remove the cable and inspect the pins on the cable
and in the serial port. Do not reinstall if the pins on
either component have any visible damage, as this
could damage the pins on the other component.
Replace the components as required.
Specify the CP Ethernet link speed by typing the
ifModeSet command.
For more information about Ethernet connectivity to
the PowerConnect B-DCX-4S, refer to the LAN
guidelines provided through the MyBrocade Web
site.
Install an operational WWN card and power the
system off/on again.
See Chapter 3, "Log In and Configuration"
for configuration information.
