Equip yourself with antistatic protection and a replacement small form-factor
pluggable (SFP) transceiver before replacing an SFP transceiver in the RAID
controller module. Also, see the initial setup information for the enclosure to
verify LED definitions.
1 If possible, use the storage management software to create, save, and print
a new storage array profile.
2 If the Recovery Guru directed you to replace a failed RAID controller module,
go to step 3, else run the Recovery Guru to identify the failed component.
3 Unpack the new SFP transceiver.
NOTE:
NOTE:
controller module, the RAID controller module enclosure, or the
expansion enclosure.
NOTE:
SFP transceiver.
4 To locate a failed SFP transceiver, view the FCIN (host channel) speed
LEDs on the front of the RAID controller modules. If an SFP transceiver
has failed, both FCIN speed LEDs for a particular port are off.
• If both FCIN speed LEDs are off for a particular port with a known
good cable, the SFP transceiver must be replaced. Go to step 6.
• If at least one FCIN speed LED is on for a particular port, the SFP
transceiver is functional. The FCIN speed LEDs indicate a channel
speed of 2 Gbps, 4 Gbps, or 8 Gbps (see "Host Channel LED
Link/Rate Indications" on page 36). Ensure that the speed indicated
by the LEDs is what is expected.
WARNING:
on system links with laser modules that operate at greater than Class 1 power
levels. Never look into the end of an optical fiber cable or open receptacle.
CAUTION:
fiber optic cables. Do not bend the fiber optic cables tighter than a 5 cm (2") radius.
5 If present, disconnect the fiber optic cable from the failed SFP transceiver.
6 Remove the failed SFP transceiver from the interface port.

Troubleshooting: Your Array
Ensure that the SFP transceiver is replaced by the same type.
