Removal and Replacement Procedures
Replacement To replace an SFP optical transceiver:
1. Ensure an ESD grounding cable is connected to the product
chassis (or approved bench ground) and your wrist.
2. Remove the replacement transceiver from its packaging.
3. Insert the transceiver into the port receptacle, then engage the
locking mechanism by rotating the wire bale up or down 90
degrees as shown in Figure 5-1.
4. Perform an external loopback test. Refer to External Loopback Test
(EFCM Basic Edition) or External Loopback Test (SAN management
application) for instructions. If the test fails, go to MAP 0000: Start
MAP to isolate the problem.
5. Reconnect the fiber-optic jumper cable:
a. Remove the protective cap from the cable connector and the
protective plug from the port optical transceiver. Store the cap
and plug in a suitable location for safekeeping.
b. Clean the jumper cable and transceiver connectors. Refer to
Clean Fiber-Optic Components for instructions.
c. Insert the keyed LC cable connector into the port’s optical
transceiver.
6. Ensure the amber port LED extinguishes. If the LED illuminates,
go to MAP 0000: Start MAP to isolate the problem.
7. Inspect the Event Log:
— At a web browser communicating with the EFCM Basic
Edition interface, select Event from the Logs menu.
— At the management server (Element Manager application),
select Event Log from the Logs menu.
Ensure an event code 510 (SFP optics hot-insertion initiated)
appears. If the event code does not appear, go to MAP 0000: Start
MAP to isolate the problem.
8. Verify port operation:
— At a web browser communicating with the EFCM Basic
Edition interface, open the Hardware View:
a. Ensure alert symbols do not appear (yellow triangle or red
diamond).
