Chapter 1
Product Summary
The Compaq StorageWorks Fibre Channel Storage Hub 12 is an active 12-port
hub for Fibre Channel-Arbitrated Loop (FC-AL) storage clusters, server
clusters, and networks, providing gigabit speed storage connectivity, modular
network scalability, and option network management.
Figure 1-1. Compaq StorageWorks Fibre Channel Storage Hub 12
Features
■Expandability and Performance - supports 12 GigaBit Interface
Converter, GBIC ports with parallel and serial identification protocols
■Flexibility - adheres to the ANSI FC-AL standard

Part Number: 340662-002 File Name: b-ch1 Product Summary.doc Last Saved On: 4/16/99 8:05 AM
■Intelligent Port Control - provides multiple data checks without
affecting performance
■Spatial Economy - takes up only 1U of rack space
■Ease of Use - provides port-bypass circuitry flexibility and simplifies
central wiring management
Functions
The Compaq StorageWorks Fibre Channel Storage Hub 12 continuously
monitors the serial data and automatically configures an FC-AL network.
Adding valid FC-AL nodes with ANSI-compliant cables is truly a plug-and-
play task. Loop nodes that are missing or inoperative are detected, and the data
is automatically routed to the next operational port and node in the loop.
The hub is transparent to the protocol. It does not consume any FC-AL
addresses and so is not addressable by an FC-AL port. Because of the
intelligent signal detection tests, only valid Fibre Channel devices will be
connected to a loop when using the hub. If an FC-AL node were to transmit
invalid Fibre Channel data, the node would be taken off the loop
automatically. Examples of node behavior that will result in a bypass state are
transmission of invalid characters, absence of frames, and invalid signal
amplitude.
Option Kit Contents

Channel Storage Hub 12 option kit.

Compaq Rack Warning
WARNING: To reduce the risk of personal injury or damage to the equipment:
■Extend the leveling jacks to the floor and ensure that the full weight of the
rack rests on the leveling jacks.
■Ensure that the stabilizing feet are attached to the rack in a standalone
rack installation.
■Couple together racks in multiple rack installations.
■Extend only one component at a time. A rack may become unstable if
more than one component is extended for any reason.
Hub Warning and Precaution
WARNING: To reduce the risk of personal injury or damage to the equipment:
■Do not disable the power cord grounding plug. The grounding plug is an
important safety feature.
■Plug the power cord into a grounded (earthed) electrical outlet that is
easily accessible at all times.
■Disconnect power from the hub by unplugging the power cord from either
the electrical outlet or from the back of the hub.

CAUTION: Protect the hub from power fluctuations and temporary interruptions
with a regulating uninterruptible power supply (UPS). This device protects the
hardware from damage caused by power surges and voltage spikes and keeps
the system in operation during a power failure.
Installation Sequence
Below is a brief summary of the steps you will follow to install Compaq
StorageWorks Fibre Channel Storage Hub 12:
1. Unpack the Hub 12 option kit and verify contents.
2. For a rack installation, attach the rack mounting hardware (page 2-4) and
install the hub into the rack (page 2-8). Then proceed to step 4.
3. For a desktop installation, install the four rubber feet (page 2-12). (This
step is for desktop installations only.) Proceed to step 4.
4. Connect the cables to the hub and perform a unit self test.
Rack-Mounting or Desktop Installation
The Compaq StorageWorks Fibre Channel Storage Hub 12 can be installed in
a rack or on a desktop; however, this guide is primarily directed toward rack
installations. Rack-mounting installations require an industry standard 19-inch
electronic enclosure rack or a Compaq 19-inch electronic rack. The rack
installation procedures provided in this guide are for the Compaq rack.
Desktop installations require a flat, level surface and the attachment of four
rubber feet on the bottom of the chassis.
When installing the hub, allow at least 6 inches of clearance at the rear panel
and at the sides of the chassis for proper air circulation.
Tools Needed
■No. 1 Phillips screwdriver
■No. 2 Phillips screwdriver

Identifying the Rack Mounting Rails and the
Chassis Slide Rails
Two rack mounting rails (long rails) and two chassis slide rails (short rails) are
used to support the hub in a Compaq rack. The chassis slide rails, which are
attached to the hub chassis, slide into the rack mounting rails, which are
attached to the front and the rear of the rack.

■Extend the leveling jacks to the floor. And ensure that the full weight of the
rack rests on the leveling jacks.
■Ensure that the stabilizing feet are attached to the rack in a standalone

2. Attach a mounting rail to the front of the rack, using two M6 x 1.0-12L
Phillips screws ➊. One screw is for the top rail hole and one screw is for
the bottom rail hole.

Installing the Hub into the Rack
1. After installing the rack mounting hardware, carefully align the hub’s
chassis slide rails with the rack mounting rails and begin sliding the hub
into the rack.
CAUTION: Be sure to keep the component parallel to the floor when sliding the
component rails into the rack mounting rail. Tilting the component up or down
could result in damage to the rails.
2. Continue to slide the hub into the rack until the latches on the front of the
slide rails engage with their alignment holes on the mounting rails. You will
know they are engaged when you hear a “clicking” noise.
