Table 2–3: Installing Cables for RA3000 Configuration Using External
Termination and Y Cables (cont.)
Step Action Refer to:
RA3000 pedestal with active/passive failover:
Install a BN38C HD68 to VHDCI cable between the
BN21W-0B Y cable of one member system and the
RA3000 Host 0 port. Install a BN21K, BN21L, or
BN31G cable between the BN21W-0B Y cables of all
other member systems.

failover: Install a BN38C HD68 to VHDCI cable
between the BN21W-0B Y cable of one member system
and the RA3000 Host 0 I/O module Host In connection.
Install a BN21K, BN21L, or BN31G cable between the
BN21W-0B Y cables of all other member systems.

RA3000 controller shelf with active/active or
active/passive failover: Install a BN38C HD68 to
VHDCI cable between the BN21W-0B Y cable of one
member system and the RA3000 Host 0 I/O module
Host In connection. Install a BN37A-0E 0.5-meter
VHDCI cable between the RA3000 controller shelf
Host 0 I/O module Host Out port and the Host 1 I/O
module Host In port. Install a BN21K, BN21L, or
BN31G cable between the BN21W-0B Y cables of all
other member systems.

RA3000 mid-bus controller shelf with
active/active or active/passive failover: Install a
BN38C HD68 to VHDCI cable between the BN21W-0B
Y cable of one member system and the RA3000 Host 0
I/O module Host In connection. Install a second
BN38C HD68 to VHDCI cable between the BN21W-0B
Y cable of another member system and the RA3000
Host 1 I/O module Host Out connection. This disables
the termination on the Host 1 I/O module. Install a
BN37A-0E 0.5-meter VHDCI cable between the
RA3000 controller shelf Host 0 I/O module Host Out
port and the Host 1 I/O module Host In port. The
connection to Host 0 I/O module Host Out port
disables the termination on that Host I/O module.
Install a BN21K, BN21L, or BN31G cable between the
BN21W-0B Y cables of any other member systems.

______________________ Note ______________________
You cannot create a mid-bus configuration using a RA3000 pedestal.
The member systems on one SCSI bus segment connected to the Host
0 port would see some devices. The member systems on the other SCSI
bus segment connected to the Host 1 port would not be able to see the
same devices.
a
The maximum length of the SCSI bus segment, including the combined length of the BN38C and BN21K
(or BN21L or BN31G) cables and internal device length, must not exceed 25 meters.
b
The maximum length of the SCSI bus segment, including the combined length of the BN38C and BN37A
cables and internal device length, must not exceed 25 meters.
