I/O modules

Four-port 8-Gb/s FC I/O module
The four-port 8-Gb/s FC I/O module (labeled 8 GbE Fibre on the latch handle) comes with
four optical (fibre) ports, one power/fault LED, and a link/activity LED for each optical port
(Figure 52). This I/O module can interface at speeds of 2, 4, and 8 Gb/s.
Figure 52 Four-port 8-Gb/s FC I/O module
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. For
an example of an SFP+ module, see Figure 20 on page 31.
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) VNX5500 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 with the duplex connectors encased in a gray plastic covering. To
determine the send or transmit (TX) and receive (RX) ferrules (connector ends), these
