Fibre Channel Features

Loop Expansion

FORTRA
FFoorrccee44
G15 and G15+ 2Gb/s Fibre Channel enclosures include a
loop expansion I/O connector on each port. This allows the connection to other
Fibre Channel enclosures, switches, servers, hubs, and other Fibre devices.

Loop Bypass and Clock Timing Circuit

Each port (A & B) includes a loop bypass circuit that monitors each slot for a loop
connection. It has two modes of operation: NORMAL and BYPASS. In
NORMAL mode, the device is connected to the loop. In BYPASS mode, the
device is either absent or non-functional and data bypasses to the next available
device until the correct device is located.
The unit also has a built-in clock recovery circuit that adjusts the timing for any
input or output that is going through the enclosure.

SFP CONNECTOR

The FORTRA
FFoorrccee44
G15 and G15+ 2Gb/s Fibre Channel enclosures use
Small Formfactor Plugs (SFP) as the Fibre I/O ports.

Dual Loops (A & B)

A single loop is required for unit operation however both loops can be used to
connect to different hosts, dual host adapters, and other devices, for flexible and
even redundant configurations. For specific connection and installation
information, refer to Chapter 4.
