EMC VNX VG2/VG8 Hardware Information Guide
Component description
Several of the Data Mover I/O modules like the four-port 8-Gb/s Fibre Channel (FC) I/O
module uses SFP or SFP+ transceiver modules to connect to LC-type optical fibre cables.
(The
“Four-port 8-Gb/s FC I/O module” on page 27
provides more detailed information
about the four-port 8-Gb/s FC I/O module.) These SFP or SFP+ transceiver modules are
input/output (I/O) devices that plug into the optical Gigabit Ethernet (GbE) port of the
Data mover I/O modules that use them. These SFP or SFP+ modules are hot swappable.
This means that you can install and remove an SFP or SFP+ module while the VG2/VG8 is
operating.
shows an example of an SFP or SFP+ module.

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 (
).
