Appendix B. Cable configurations
This appendix shows examples of cable configurations for the 2104 Model TS4.
Some of the configurations are valid for all the adapters that the 2104 Model TS4
supports. Other configurations are valid only for particular types of adapters. Also
shown are configurations that are invalid. Do not use any configuration that is
shown as invalid; unexpected results might occur.
Valid configurations
Only point-to-point connections are allowed between the SCSI interface cards in a
2104 Model TS4 and the SCSI adapter card or integrated SCSI port in a host
system.
You can attach a 2104 Model TS4 with only one SCSI interface card to one SCSI
adapter or integrated SCSI port. You can attach a 2104 Model TS4 with two SCSI
interface cards to two SCSI adapters or integrated SCSI ports.
When you use the internal connector on the adapter card, do not use the
corresponding external connector to connect to a 2104 Model TS4.
You can configure a 2104 Model TS4 to support either a single SCSI bus or a dual
SCSI bus. The setting of the SCSI bus split switch on the card in the 2104 Model
TS4 defines which configuration is to be used.
An RS/6000 or IBM
Eserver
pSeries computer uses one of the following SCSI
adapters to connect to the 2104 Model TS4:
v
PCI Dual-Channel Ultra3 SCSI Adapter (type number 4-Y, feature code 6203)
This dual-channel adapter has two external SCSI connectors and two internal
SCSI connectors. Each pair, consisting of one external and one internal
connector, is connected to a separate SCSI channel.
v
PCI 4-Channel Ultra3 SCSI RAID Adapter (type number 4-X, feature code 2498)
This 4-Channel adapter has four external SCSI connectors and two internal SCSI
connectors. The Channel 1 and Channel 2 external connectors share the same
SCSI bus as the corresponding Channel 1 and Channel 2 internal connectors.
The Channel 3 and Channel 4 external connectors have their own non-shared
SCSI bus.
v
PCI-X Dual Channel Ultra320 SCSI Adapter (type number 5702, feature code
5712)
This dual-channel adapter has two external SCSI connectors and two internal
SCSI connectors. Each pair, consisting of one external and one internal
connector, is connected to a separate SCSI channel.
v PCI-X Dual Channel Ultra320 SCSI RAID Adapter (type number 5703, feature
code 5703)
This dual channel adapter has two Ultra320 SCSI busses, each with one internal
and one external connector.
An RS/6000 or IBM
Eserver
pSeries computer that is running Linux for pSeries
uses the following SCSI adapter to connect to the 2104:
v
PCI Dual-Channel Ultra3 SCSI Adapter (type number 4-Y, feature code 6203):
