FC420 Fibre Channel Bridge
Quick Reference Guide
This Quick Reference Guide
explains how to install one
FC420 Fibre Channel bridge in
an ATL M1500 library, or up to
three FC420 bridges in an
ATL M2500 library.
If you are unfamiliar with any of
the information or procedures in
this document, the Quantum
Help Desk is ready to assist you
24 hours a day, 7 days a week.
To reach the Help Desk, call the
number for your area listed in

Step 1: Prepare for Installation
1Make sure your system meets the following requirements:
•Point-to-point/fabric or arbitrated public or private loop topology
•For fabric configurations, a Quantum-approved Fibre Channel switch
•Quantum-approved network management software package
•Windows®NT 4.0 SP6 or later, Windows 2000 SP2 or later, Solaris®
8 and 9, or other Quantum-approved operating system
Make sure you have the tools recommended for this procedure:
•#1 PHILLIPS®screwdriver
•Flat blade screwdriver
2Verify the contents of the FC420 Bridge Upgrade Kit, referring to the
Quantum FC420 Upgrade Kit Contents List (PN 6473023).
3Take precautions to prevent electrostatic discharge (ESD). These
precautions include:
•Wearing a properly grounded antistatic wrist strap
•Wearing other antistatic apparel (smock, footwear, etc.)
•Handling library components with care and keeping the FC420 bridge in
its antistatic packaging until you are ready to install it
Note: For a complete list of Quantum-approved networking hardware,
software, and operating systems, contact the Quantum Help Desk or an
authorized Quantum sales representative.
Note: The FC420 Fibre Channel bridge can only be used in LVD-
configured libraries.
Caution: The small form-factor pluggable (SFP) connector on the
FC420 bridge is removable; however, the SFP connector should only be
removed by authorized repair personnel. Removal of the SFP connector
may void the warranty.
Caution: Failure to take adequate antistatic precautions may result in
damage to the FC420 bridge or other library components.

Step 2: Install FC420 Bridge(s)
1Turn off the library by pressing the power switch on each power supply at the back of the library.
2Remove the power cable from the back of the library.
3If you are installing the first FC420 bridge in the library, use a flat blade screwdriver to loosen the two large
thumbscrews securing the primary electronics module to the back of the library (see figure 1), then pull the primary
electronics module from the chassis using the round handles.
4If you are installing a second or third FC420 bridge in an ATL M2500 library, remove the six screws that secure the
secondary electronics module to the back of the library.
Save the six screws for reinstallation of the secondary electronics module.
5Remove the two screws securing the expansion slot cover plate to the back of the electronics module and remove
the cover plate.
Save the screws for use later in this installation. Save the cover plate for future use.
6Remove the screws securing the hold-down clamp.
Save the clamp for use later in this installation.
7Carefully remove the new FC420 bridge from its antistatic packaging.
Caution: Hold the FC420 bridge by the edges, avoiding contact with the components and connectors.

8Insert the FC420 bridge into the expansion slot and press it down gently until it is seated securely.
9Secure the FC420 bridge to the electronics module using the two mounting screws you removed in step 5.
10 Repeat steps 5 through 9 to install any additional FC420 bridges.
11 Reattach the hold-down clamp to secure the FC420 bridge in the slot.
12 Slide the electronics module back into the library chassis until it is fully seated.
13 Secure the electronics module to the chassis. To secure:
•The primary electronics module, use a flat blade screwdriver to tighten the two thumbscrews.
•The secondary electronics module, reinstall the six screws you removed in step 4.
Step 3: Cabling the FC420 Bridge(s)
Each FC420 bridge has 2 SCSI ports and 1 Fibre Channel port. Follow these guidelines to establish SCSI and Fibre
cabling:
•If the library is equipped with DLT8000 tape drives, the FC420 bridge can accommodate up to four drives per SCSI
port.
•If the library is equipped with SDLT 220, SDLT 320, or HP LTO Gen 1 drives, the FC420 bridge can accommodate up
to two drives per SCSI port when the bridge is set for 2 Gb data transfers, or one drive per SCSI port when the bridge
is set for 1 Gb data transfers.
•If the library is equipped with HP LTO Gen 2 or SDLT 600 drives, the FC420 bridge can accommodate one drive per
SCSI port when the bridge is set for 2 Gb data transfers.
•To maximize data throughput, reduce the number of tape drives per FC420 SCSI port.
•The open connector on each drive must be terminated.
•Because of the physical characteristics of the SCSI cable connectors, attach a SCSI cable from the upper SCSI port
on the SCSI controller in the primary electronics module to a SCSI connector on drive 1 first, then attach a SCSI
cable from SCSI port 0 on the FC420 bridge (the left VHDC1 connector) to the lower SCSI port on the library SCSI
controller.
•To ensure access to the library robotics, all Fibre Channel cables from the library should connect to a switch or
similar device serving the storage area network (SAN).
For complete cabling instructions, refer to the FC420 Fibre Channel Bridge Option User’s Guide (PN 6473031).
Note: HP LTO Gen 2 and SDLT 600 drives cannot be used when the bridge is set for 1 Gb data transfers.

Step 4: Configure FC420 Bridge Firmware
A command-line interface (CLI) is provided to assist with FC420 bridge configuration, maintenance, and system
diagnostics. Specifically, you can use the CLI to:
•Configure the Ethernet, Fibre Channel, and SCSI ports
•Create device maps
•Obtain FC420 bridge status information
•Log FC420 bridge events
•Report SCSI and Fibre Channel device information
For complete configuration instructions, refer to the FC420 Fibre Channel Bridge Option User’s Guide (PN 6473031).
Note: If your library is equipped with an MC300 Prism Management Card, you can change the configuration of
the FC420 bridge, you can do so using the Prism Management Console Web pages (see the MC300 Prism
Management Card User’s Guide, PN 6311631).
