Features
The Fibre Channel Hub is designed with seven modular
user configurable interface ports. These seven ports
comply with the GigaBit Interface Converter (GBIC)
Specification. GBICs are available in two media types:
Long-Wave optical
Short-Wave optical
This section covers both the Fibre Channel Hub and the
GBICs.
The following list summarizes the features of the Fibre
Channel Hub:
Seven configurable media-interface optical ports
providing high performance.
Plug and Play provides fault tolerance for online
system configuration changes.
Modular Gigabit Interface Converter (GBIC)
transceiver design allows you to use ports when
needed.
Cascadable ports allows up to 127 connections
(where one port is reserved for connection to fabric or
switch active ports) or support of multiple loop
implementations.
Simplified cable management can be used for
centralized storage management applications.
Hot pluggable GBIC provides an optimal solution for
entry storage interconnect needs.
Half-rack width (1U = 1.75 in.) low profile hub
packaging offers highest port density in single 1 unit
height rack mount.
Auto-sensing power-supply - supports 95 to 250 V ac
and 50 to 60 Hz.
Description
The IBM Fibre Channel Hub is a 7-port central
interconnection for Fibre Channel Arbitrated Loops that
follow the ANSI FC-AL standard. Each Fibre Channel Hub
port receives serial data from an attached node and
retransmits the data out of the next hub port to the next
node attached in the loop. Each reception includes data
regeneration (both signal timing and amplitude) supporting
full-distance optical links.
The Fibre Channel Hub detects any loop node that is
missing or is inoperative and automatically routes the data
to the next operational port and attached node in the loop.
LED indicators provide status information to indicate
whether the port is active or bypassed.
Each port requires a Gigabit Interface Converter (GBIC) to
connect it to each attached node. The Fibre Channel Hub
supports any combination of short-wave or long-wave
optical GBICs. The GBICs are
hot-pluggable into the Fibre
