Maintaining the SilkWorm 3800

The SilkWorm 3800 does not require any regular physical maintenance, and is designed to
minimize the chance of failure. It includes diagnostic tests and field-replaceable units.
Diagnostic Tests
In addition to POST, Fabric OS includes diagnostic tests to help troubleshoot the hardware and the
firmware. This includes tests of internal connections and circuitry, fixed media, and the
transceivers and cables in use. 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.
All diagnostic tests are run at link speeds of both 1 Gbit/sec and 2 Gbit/sec.
Note:
For information about specific diagnostic tests, refer to the Brocade Fabric OS Procedures Guide.
Field-Replaceable Units (FRUs)
You can replace the power supplies, fan assemblies, and motherboard in the field without the use of
special tools. The power supplies and fan assemblies are keyed to ensure correct orientation during
installation. Replacement instructions are provided with all replacement units ordered.

Diagnostic tests may temporarily lock the transmit and receive speed of the links
during diagnostic testing.
Warning
The SilkWorm 3800 may have more than one power cord. To remove
all power from the switch by disconnecting all power cords in use.
Power Supplies
The power supplies (one or two) are hot-swappable if one power supply remains operating
They are identical and fit into either power supply slot.
Fabric OS identifies the power supplies as follows (viewing the switch from the non-port
side; see Figure 3-2 on page
•
Power supply #1 is on the right when viewing the switch from the non-port side.
•
Power supply #2 is on the left when viewing the switch from the non-port side.
Any of the following methods can be used to determine whether a power supply requires
replacing:
•
Check the Power Supply LED next to the AC switch (see
Side of the Switch on page
•
Enter the psshow command.
•
In Web Tools, click the Power Status icon.
