Diagnostic testing
In addition to POST, the Fabric OS includes diagnostic tests to troubleshoot the hardware and
firmware. This includes tests of internal connections and circuitry, fixed media, and the
transceivers and cables. The tests are implemented by command, either through a Telnet session
or through a terminal set up for a serial connection to the switch. Some tests require the ports to be
connected by external cables, to allow diagnostics to verify the serializer/deserializer interface,
transceiver, and cable. Some tests require loopback plugs.
Diagnostic tests are run at link speeds of 1 Gbps, 2 Gbps, 4 Gbps, and 8 Gbps. For information
about diagnostic tests, refer to the Brocade Fabric OS Administrator’s Guide.
Checking the FRUs
The power supplies and the fan assemblies can be replaced on site without the use of special
tools. The power supplies and fan assemblies are keyed to ensure correct orientation during
installation.
NOTE
The removal and replacement procedures are shipped with the replacement FRUs. Those
procedures are not described here.
Power supply
The two power supplies are hot-swappable if replaced one at a time. They are identical and fit into
either slot.
Fabric OS identifies the power supplies as follows (viewing the switch from the port side):
•
Power supply #1 is on the left.
•
Power supply #2 is on the right.
To determine if a power supply requires replacing, do either of the following:
•
Check the power supply status LED (
). If the power supply status LED is not on, verify
that the power supply is on and seated and the power cord is connected to a functioning power
source. If the light does not turn green, the power supply may need to be replaced.
•
In Web Tools, click the Power Status icon.
•
Type the psShow command at the command prompt to display power supply status:
switch:admin> psshow
Power Supply #1 is OK
Power Supply #2 is OK
