2.7 Connecting the Enclosure to FC Host and Disk Ports
The (I/O) interface module provides a Fibre Channel interface via small
form-factor pluggable connection (SFPs) that can be either copper
HSSDC-2 connectors for copper or optical (LC optical cable)
connection. Copper (1M max.) SFP to SFP patch cables are also
supported (for enclosure to enclosure connection only).
Each I/O or Loop Resiliency Circuit board houses Port Repeater chips
that re-drive the Fibre Channel signals. Each of the LRC I/O boards also
houses a number of Port Bypass circuits. The function of these circuits
is to bypass the loop connections to empty drive bays or any disk drive
which is not operating correctly

OTE
:
There are no external terminators required with Fibre Channel
architecture and any drive may be hot plugged during operation.
• You can connect the EF2800 directly to one or more FC HBAs or to
a FC switch or hub
(Figure 32). Each Storage Manager has two FC
host ports.
• You can attach FC disk drives to all of the EF2800’s FC disk ports.
• You can connect up to 248 FC devices to the EF2800, including the
16 internal hard drives.
