Transceivers
The mpx100/100b supports SFP o ptical transceivers for the FC por ts. A transceiver converts electrical
signals to and from optical laser signals to transmit and receive da ta. Duplex fiber optic cables plug into
the transceivers, which then connect to the devices. A 1 Gb/s/–2 Gb/s FC port is capable of transmitting
at 1 Gb/s or 2 G b/s; however, the transceiver must also be capable of delivering these rates.
The SFP transceivers are hot-pluggable. This means you can remove or install a transceiver while
the mpx100/100b is o perating without harming the mpx100/100b or the transceiver. However,
communication with the connected device will be interrupted.
iSCSI/GigabitEthernetports
The iSCSI/Gigabit Ethernet ports shown in Figure 17 are RJ-45 connectors that provide connection to an
Ethernet network through a 10/100/1000 Base-T Ethernet cable. The ports are labeled GE1 and GE2.
These ports have two L EDs: the Link Status LED (green) and the Activity LED (green). The Link Status LED
illuminates continuously when an Ethernet connection has been established. The Activity LED illuminates
when data is being transmit ted or received over the connection.
