Installing the PowerVault 35F: Dell PowerVault 35F User's Guide
WARNING: The PowerVault 35F has been qualified with a specific set of GBICs. Using a GBIC that
has not been qualified by Dell may cause the PowerVault 35F to operate improperly.
3. With the PowerVault 35F powered off, connect the PowerVault 35F into your Fibre Channel environment using
the appropriate cabling. The connectors on the PowerVault 35F are keyed. Be sure to insert the cable connectors
in the proper orientation.

SCSI Connection

The PowerVault 35F supports Fast/Ultra Wide SCSI. The PowerVault 35F is factory configured to support a
Differential SCSI bus. Two 68-pin D-shell connectors are located on the rear panel of the unit, allowing the unit to be
attached in the middle or at the end of a SCSI bus. If the PowerVault 35F is located at one end of the SCSI bus, an
external terminator should be installed. Two terminators are provided with the PowerVault 35F.
Differential SCSI support is indicated by this symbol on the rear of the PowerVault 35F.
NOTE: The PowerVault 35F only supports Differential SCSI cables and terminators. Single-Ended SCSI
connectors and LVD SCSI connectors are not supported.
The PowerVault 35F supplies termination power (TERMPWR) on each SCSI bus. A self-resetting fuse is used that
will reset after the fault is cleared.
To connect the PowerVault 35F to a SCSI bus:
1. Power off your SCSI devices and the PowerVault 35F.
2. Connect a SCSI cable to one of the SCSI connectors on the back of the bridge.
3. Connect the other end of the SCSI cable to the next SCSI device on the bus. It is recommended that tape devices
be evenly distributed between SCSI buses for best performance.
4. If the PowerVault 35F is at the end of the SCSI bus, place the terminator provided with the bridge on the
PowerVault 35F's other SCSI connector on the same bus. If the bridge is not at the end of the bus, attach a
second SCSI cable to the other SCSI connector. Connect this cable to the next device on the bus.
