The four-port 8-Gb/s FC I/O module uses SFP+ transceiver modules to connect to LC-type
optical fibre cables. These SFP+ transceiver modules are input/output (I/O) devices that
plug into the FC port of the FC I/O modules. These SFP+ modules are hot swappable.
Be careful when replacing or swapping out SFP+ modules, your Data Mover will lose
access to the SP or tape drive to which it is connected
This means that you can install and remove an SFP+ module while the Block and File
(Unified) VNX5300 platform is operating.
Note: The Lucent Connector (LC) type interface was developed by Lucent Technologies
(hence, Lucent Connector). It uses a push-pull mechanism. LC connectors are normally
held together in a multimode duplex configuration with a plastic clip. These cables are
usually colored orange for OM2 type cables and aqua for OM3 type cables. These cables
have the duplex connectors encased in a gray plastic covering. To determine the send or
transmit (TX) and receive (RX) ferrules (connector ends), these cables will show a letter
and numeral (for example A1 and A2 for the TX and RX, respectively) or a white and yellow
rubber gasket (jacket) for the send or transmit (TX) and receive (RX) ends.
