D.5.3 Cable Type Tests
A range of adapter cables available for the DEC MicroServer provide easy
connection to various interface standards. Each type of cable contains a unique
identifier.
To determine which cable is attached to a particular line, verify that there is
no loopback connector on the port, and then issue the following command:
TEST CABLE_TYPE/CH
n
To determine which cables are attached to the DEC MicroServer, verify that
there are no loopback connectors on any port, and then issue the following
command:
TEST CABLE_TYPE/ALL
For each cable, the test displays the following message:
type Cable on Channel n
If, however, any port has a 50-way loopback connector attached to it, the test
displays the message:
H3199 Loopback on Channel
n
If the test cannot determine the type of cable, it displays the following message:
Unsupported Cable on Channel
n, Cable Code xxxx
If this message appears for a supported cable, check that the cable is correctly
connected to the socket, and then retry the test. If the message appears again,
the adapter cable is probably faulty.
D.5.4 Soak Testing the DEC MicroServer
The DEC MicroServer’s internal tests are usually run during power up or when
the system is being reloaded. You can, however, run internal tests continuously
to "soak test" a DEC MicroServer unit. To run a soak test, perform the
following steps:
1.
Attach the appropriate loopback connectors to the DEC MicroServer’s
synchronous ports.
2.
Enter the following command:
>>>TEST CONTINUOUS
The DEC MicroServer now runs the internal test program continuously. To
reload the system, power down the DEC MicroServer, wait 3 seconds, and
power up the DEC MicroServer.
