Perform Loopback Tests
This section describes the procedures to perform an:
■
Internal loopback test—An internal loopback test checks UPM 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 test—An external loopback test checks UPM 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 multi-mode or single-mode loopback plug must be inserted in the port
receptacle.
Internal Loopback Test
To perform an internal loopback test for a single port or a UPM card (four ports):
1. Notify the customer a disruptive internal loopback test will be performed on a
port or UPM card. Ensure the customer’s system administrator quiesces Fibre
Channel frame traffic through the port or UPM card, and sets attached devices
offline.
Note:
At the start of the loopback test, the port or UPM card can be online, offline,
blocked, or unblocked.
