Troubleshooting the Brocade DCX 8510-8 TABLE 29
Issue Possible cause Recommended action
Entire chassis powers off
automatically. Power supplies are
inadequate to support the
installed components. Add an additional power supply.
Several or all components are
not operating. One or both power cables
may not be connected to a
live source. Ensure that both power cables are connected to live
outlets.
One or both AC power
switches might be off. Ensure that both AC power switches are on (AC
switches light up green when on).
Serial connection is faulty or
serial port logs have incorrect
or missing information. Serial cable is not
connected correctly. Ensure that the cable is firmly connected to
workstation computer and to the Brocade DCX
8510-8.
Terminal emulator
application parameters are
not set correctly. Ensure that the terminal emulator application is
configured as follows: 9600 bits per second, 8
databits, no parity, 1 stop bit, no flow control.
Serial port might be
incompatible (only RS-232
is supported). Ensure that the Brocade DCX 8510-8 is connected
to an RS-232 port. RS-232 serial ports might
experience difficulties due to corner-case
incompatibilities of the standards.
Pins on the serial cable or
serial port might be
damaged. 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.
CP Ethernet link speed is
different than expected or a
link cannot be established. There might be a conflict
with the CP Ethernet link
speed negotiation set up
by the network. Specify the CP Ethernet link speed by typing the
ifModeSet command.
For more information about Ethernet connectivity to
the Brocade DCX 8510-8, refer to the LAN
guidelines provided through the MyBrocade website.
Configuration data is
inaccurate or cannot be
accessed. Chassis was powered
off/on while a WWN card
was uninstalled or failed. Install an operational WWN card and power the
system off/on again.
The Brocade DCX 8510-8
was rebooted while an
WWN card was
uninstalled or failed.
Initial setup results in IP
address/Domain ID conflict. The Brocade DCX 8510-8
was connected to the
fabric before being
configured. Refer to the Fabric OS Administrator's Guide for
configuration information.
