8 Insert the FC420 bridge into the expansion slot and press it down gently until it is seated securely.
9 Secure 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.
