Electrostatic discharge can damage sensitive components. To prevent electrostatic
discharge damage to the storage expansion enclosure, use proper anti-static
protection when handling components.
1.
Use the DS Storage Manager client software to print a new storage subsystem
profile.
2. Using the Recovery Guru, identify the failed component that needs to be
replaced.
3. Check the Fault LEDs to locate the failed SFP module. If a fault is detected,
the amber Fault LED is on.
Attention: Potential loss of data access - To prevent loss of access to data,
remove only the SFP module that has a failed status in the storage
management software and has Port Bypass LED lit.
4. Put on anti-static protection.
5.
Unpack the new SFP module. Verify that it is the same type of module you
are replacing. If it is not, contact IBM Customer and Technical Support.
Attention:
v
The EXP395 is not supported at 2 Gbps data rate operation attached to the
DS3950; therefore, 2 Gbps SFPs are not supported in the EXP395.
v The speed of the SFP module determines the maximum operating speed of
the fibre channel port in which the SFP is installed. For example, a 2-Gbps
SFP that is plugged into a 4-Gbps-capable port will limit the speed of that
port to a maximum of 2 Gbps.
v
Handle and install fibre-optic cables properly to avoid degraded
performance or loss of communications with devices. For specific handling
guidelines, see “Handling fibre-optic cables” on page 36.
6.
Disconnect the interface cables from the SFP module.
7. Remove the failed SFP module from the controller.
8. Install the new SFP module into the controller.
9. Reconnect the interface cable.
10. Check the Bypass and Fault LEDs for the new SFP module.
11.
Based on the status of the Bypass and Fault LEDs, choose one of the following
steps:
Fiber-optic cable
(Host interface cable)
SFP
Transceiver
