VFS113 Rack/Desktop Model User’s Guide

You must use the proper SCSI cables on the model you purchased. For example, if you purchased the LVD model, you must use LVD-qualified SCSI cables. Symbols on the rear panel tell you which model you have.

 

LVD/SE (wide, Ultra-2 SCSI),

SCSI 68-pin SCSI (LVD/SE model)

Ultra wide, 68-pin SCSI (HVD model)

SCSI DIFF

To connect devices to the SCSI channels:

1The router must be turned off.

2Turn off the SCSI devices you want to connect.

3Connect one end of a SCSI cable to a SCSI channels on the back of the router. See Figure 2-9 on page 2-7.

4Connect the other end of the SCSI cable to the SCSI device.

Make sure each device on the SCSI bus has a unique address (the VFS113 uses address 7 by default).

5Make sure that each channel is properly terminated.

Termination on the LVD/SE model is always enabled at the router. You must also terminate the SCSI bus at the device end.

Termination on the HVD model can be disabled for operation in the middle of the bus.

Connecting to the Fibre Channel Port

You can connect the router directly to an FC HBA or to an FC switch or hub. You must use proper FC components (for example, GBICs, media interface adapters [MIAs], and FC cable, either optical or copper). Contact Chaparral for information on components tested by Chaparral and advice on attaching SCSI devices in an optimal manner for your applications.

You will need to purchase a GBIC through your distributor. The GBIC connector is available in four different versions:

Copper (Active)

DB-9

HSSDC

Optical

Short wave

Long wave
