Understanding and Maintaining Components Optical SFP Transceiver (7320SS only) The Fibre Channel host I/O card uses a hot-swappable Small Form-Factor Pluggable (SFP) transceiver (Figure 5-18). The SFP optical transceiver provides operations up to 2.5 Gigabits/sec. The transceiver includes a lost signal detect circuit that provides TTL logic high output when an unusable input signal is detected. Figure 5-18 Optical Transceiver The SFP transceiver is Class 1 Laser safety compliant and conforms to Class 1 eye safety standards. ! Caution: Do not look into the laser light beam for any extended period of time. Dust covers are provided to protect the optical transceivers' optics. Adaptec highly recommends using the dust covers provided when a connector is not in place. Figure 5-19 shows how the dust covers fit into the transceiver.

Understanding and Maintaining Components
Optical SFP Transceiver (7320SS
only
)
The Fibre Channel host I/O card uses a hot-swappable Small
Form-Factor Pluggable (SFP) transceiver (
Figure 5-18
). The SFP
optical transceiver provides operations up to 2.5 Gigabits/sec. The
transceiver includes a lost signal detect circuit that provides TTL
logic high output when an unusable input signal is detected.
Figure 5-18
Optical Transceiver
The SFP transceiver is Class 1 Laser safety compliant and conforms
to Class 1 eye safety standards.
Caution:
Do not look into the laser light beam for any extended
period of time.
Dust covers are provided to protect the
optical
transceivers’ optics.
Adaptec highly recommends using the dust covers provided when
a connector is not in place.
Figure 5-19
shows how the dust covers
fit into the transceiver.
