McDATA Sphereon 4500 Fabric Switch Installation and Service Manual
• Transceiver - Type of port transceiver (Shortwave Laser, Longwave
Laser, Long Distance Laser, Unknown, or None).
• Distance - Port transmission distance (Short, Intermediate, Long,
Very Long, or Unknown).
• Media - Type of optical cable used (Singlemode, multimode
50-micron, multimode 62.5-micron, or Unknown).
• Speed - Operating speed (Not Established, 1 Gbps, or 2 Gbps).
Perform Port Diagnostic Loopback Tests
Port diagnostics consist of internal and external loopback tests.
The tests are performed on any selected port at the SANpilot
interface or the management server (Sphereon 4500 Element Manager
application). The tests are described as follows:
• Internal loopback test - An internal loopback test checks internal
port, serializer, and deserializer circuitry and checks for the
presence of an optical transceiver, but does not check fiber-optic
components of the installed transceiver. Operation of the attached
device is disrupted during the test.
• External loopback test - An external loopback test checks all port
circuitry, including fiber-optic components of the installed optical
transceiver. To perform the test, the attached device must be
quiesced and disconnected from the port, and a singlemode or
multimode loopback plug must be inserted in the port.
Internal Loopback
Test (SANpilot
Interface)
To perform an internal loopback at the SANpilot interface:
1. Notify the customer that a disruptive internal loopback test is to
be performed. Ensure the customer’s system administrator
quiesces Fibre Channel frame traffic through the port, and sets the
attached device offline.
NOTE: A small form factor pluggable (SFP) optical transceiver must be
installed in the port during the test. A device can remain connected
during the test.
2. When the SANpilot interface opens, the View panel and Switch
page appear as the default. At the View panel, select the Operations
option at the left side of the panel. The Operations panel opens
with the Switch page displayed.
