ED-64M Director Operating Features
Port Diagnostics
Maintenance personnel can perform the following tests through the
Port Diagnostics
option on the Product Manager Maintenance
menu.
◆
Internal Loopback
— an 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, but the test momentarily blocks the port and is disruptive to
the attached device.
◆
External Loopback
— an external loopback test checks all 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, and a multimode or
singlemode wrap plug must be inserted in the port receptacle.
