•
Each end of twisted pair ground must be connected to chassis ground
•
When calculating the overall length of the bus, be sure to include the internal cabling of the
module, which is 27 inches (69 cm) for all models
•
Cables of different impedance should not be used together
For additional specifications, refer to ANSI X3.131-1994 or later
Note : This equipment has been tested for electromagnetic emissions and immunity using
good quality shielded cables. If you use poor quality or unshielded cables, they may not
comply with national and international rules.
Connecting to the Host
To connect the PowerLoader to a host computer system:
1) Verify that the following hardware/software are available:
•
The host system has a compatible SCSI controller and the appropriate driver software
installed. (If you have questions about installation for specific host systems, call your
Technical Support representative.)
•
The cables you are using meet the required specifications for type and length
•
The terminator type matches your system.
2) If the PowerLoader is the only SCSI device you are connecting to the host, do the following:
•
Connect the cable from the host to one of the SCSI connectors
•
Attach the terminator to the outgoing SCSI connector
3) If the PowerLoader is one of several units you are connecting to the host, connect them in a
daisy-chain by doing the following:
•
Connect the cable from the host, to the incoming SCSI connector of the first SCSI device
•
Connect the cable from the outgoing connector of the first device to the incoming connector of
the second SCSI device, and so on. You can connect them in any order
•
Attach the terminator to the outgoing SCSI connector of the last device in the chain
4) If the PowerLoader is connected to 2 hosts at the same time:
•
In the two-host configuration, a separate SCSI bus runs from each host to a different drive. As
shown in the following illustration, each incoming SCSI bus attaches to the left connector of
each pair. Place a terminator at the right connector of each pair.
