AlphaServer 8400
3.212 Alpha Servers
Step 5—System I/O Modules


KFTIA-AA system I/O module included with Base Server; KFTHA-AA included with Expanded Base Server—any
combination of KFTIA or KFTHA modules can be added for a maximum of three.
- Maximum twelve I/O channels available on AlphaServer 8400.


System Building Block requires the selection of one I/O module.
KFTHA-AA System I/O module with four I/O channels for PCI or XMI plug-in units
KFTIA-AA System I/O module with one I/O channel for PCI or XMI plug-in units. Includes
- two 802.3 twisted-pair Ethernet ports—requires BN26M cable per port
- single-ended SCSI-2 port—requires BN21H cable
- three
FWD (Fast Wide Differential) SCSI-2 ports—requires CK-KFTIA-AA and
BN21K cable per port
One of the following optional FDDI daughter cards can be added to KFTIA-AA—see Step 8 for
cables.
- Single attachment station multi-mode fiber card (DEFPZ-AA) or
- Twisted-pair copper card (DEFPZ-UA)
Prestoserve (DJ-ML300-BA) can be added to KFTIA-AA
BN26M-xx Ethernet twisted-pair cable; 8-pin MP to 8-pin MP, screened, EIA/TIA Category 5 cable.
BN21H-xx SCSI-2 Single-ended cable; 50-pin male straight to 50-pin male straight. Connects KFTIA-AA
single-ended SCSI-2 port to StorageWorks shelf.
CK-KFTIA-AA Cabinet kit for FWD (Fast Wide Differential) SCSI-2 port. One kit required for each used port on
KFTIA-AA, maximum three per KFTIA-AA. Cabinet kit includes Y-cable and FWD terminator.
BN21K-xx SCSI-2 Fast Wide Differential cables; 68-pin male straight to 68-pin male right-angle. Connects
KFTIA-AA Fast Wide Differential SCSI-2 ports to DWZZA-VA or DWZZB-VW.
BN21K-02* Connects from KFTIA FWD port to DWZZB-VW in BA660-AB System cabinet (rear)
Connects from KFTIA FWD port to DWZZB-VW in BA661-AA in DWLPB-xx PIU
BN21K-03* Connects from KFTIA FWD port to DWZZB-VW in BA660-AB System cabinet (front)
BN21K-05/10 Connects from KFTIA FWD port to DWZZB-VW in BA660-AB Expansion cabinet (front or rear)
Connects from KFTIA FWD port to DWZZB-VW in BA356-JB in SW500 and SW800 Cabinets
* Manufacturing may substitute correct cable length depending on configuration.
Step 6—Storage Controllers


KFTIA-AA included with each Base Server; KFTHA-AA
included with Expanded Base Server—PCI, EISA, and
XMI storage controllers can be added.
- Requires corresponding PCI plug-in unit (DWLPB-
AA/AB/BA/BB) or XMI plug-in unit (DWLMA-
AA/BA).


DWZZA-AA requires minimum revision E02 for
connecting any Fast Wide Differential SCSI-2 port from
KFTIA-AA or KZPSA-BB to TZ8xx tape loaders.


DWZZB-VW Fast Wide Differential Single-ended SCSI
Converter requires minimum revision A01 for connecting
FWD SCSI-2 signals from KFTIA-AA or KZPSA-BB to
BA356-JB StorageWorks Shelf.


System maximum of four KZPSC or KZPAC SCSI
RAID controllers.




Tape and optical devices are not supported on KZPSC or
KZPAC SCSI RAID controllers.
PCI-based Storage Controllers
KZPSA-BB PCI Fast Wide Differential SCSI Adapter—OpenVMS V6.2-1H3 supports eight per PCI,
maximum 26 per system. DIGITAL UNIX supports eight per PCI, maximum 32 per system (uses one
PCI slot). Provides one SCSI-2 bus. KZPSA supports DECsafe Available Server.
BN21K-xx SCSI-2 Fast Wide Differential cables—68-pin male straight to 68-pin male right-angle. Connects
KZPSA-BB Fast Wide Differential SCSI-2 port to DWZZA-VA or DWZZB-VW.
BN21K-01* Connects from KZPSA to DWZZB-VW in BA660-AB System cabinet (rear)
Connects from KZPSA to DWZZB-VW in BA661-AA in DWLPB-xx PIU
BN21K-02* Connects from KZPSA to DWZZB-VW in BA660-AB System cabinet (front)
BN21K-05/10 Connects from KZPSA to DWZZB-VW in BA660-AB Expansion cabinet (front or rear)
