8-Gb/s FC ports
The Block and File (Unified) VNX5300 platform SP comes with four optical (fibre) 8-Gb/s
Fibre Channel (FC) ports (labeled 8GB fibre 2, 3, 4, and 5) on the rear of each SP (A and B).
These ports provide an optical interface for connecting to the front end. These ports
support 2-, 4-, and 8-Gb/s Fibre Channels using a small form-factor pluggable (SFP+)
transceiver module. The SFP+ transceiver modules connect to Lucent Connector (LC) type
optical fibre cables. These SFP+ transceiver modules are input/output (I/O) devices.
These SFP+ modules are hot swappable. This means that you can install and remove an
SFP+ module while the SP is operating.

The 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
multimode optical fiber type cables and aqua for OM3 multimode optical fiber 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 (Figure 21 on page
