Using Maintenance Features
Running Port Diagnostics
The Port Diagnostics option is used by service personnel to run
internal and external loopback tests on any port or all ports on a port
card.
The tests are:
◆
Internal loopback test — Checks port card circuitry, but does not
check fiber optic components of a port transceiver. The test is
performed with a device attached to the port; however, the test
momentarily blocks the port and is disruptive to the attached
device.
◆
External loopback test — Checks port card circuitry, including
fiber optic components of a port transceiver. To perform the test,
the attached device must be quiesced and disconnected from the
port. Also, a multimode or single-mode wrap plug must be
inserted into the port receptacle.
