Serial Communications
The Ultra S2S RAID Controller supports two serial asynchronous communication
channels. The two channels are labeled on the S2S Interface Card as Serial A and B.
The Serial A connector is an RJ45 type connector and provides the
communication link to a VT-100 (or equivalent) terminal and is used to configure
the RAID subsystem.
The Serial B connector is an RJ11 type connector and provides the communication
link between two Ultra S2S RAID Controller controllers for basic communications
in a Dual-Active configuration. Cables are included in the accessory kits.

SCSI Functions
The SCSI ID of the Ultra S2S RAID Controller is set to a target address (SCSI
ID) of 0 by default on power up. This setting should be adequate for a single
cabinet configuration in stand-alone solutions. When multiple cabinets are
used the target address of each Ultra S2S RAID Controller must be set to a
unique SCSI ID that is available on the host SCSI bus. Use the "SCSI ID
Menu > Set RAID Module ID" selection located on the CR8e operator
control panel to set the target address. Refer to the CR8e User's Guide, "Using
the CR8e" chapter – Options Menu selection.
When the SCSI ID is changed, the subsystem will require power cycling to
allow the new settings to take effect. Note that you will under normal
conditions be setting the Drive IDs as the next step, you can set the RAID
Module ID then access the menu and change the setting for SAFTE Chain ID
functions before power cycling the subsystem. This saves you from power
cycling the subsystem twice.
Each drive on each channel of the Ultra S2S RAID Controller must be
configured for a target address (SCSI ID) that is different from all other
devices. The CR8e subsystem will automatically set the target address of each
device during the power cycle after the appropriate "SAFTE Chain ID"
selection is set on the CR8e operator control panel. (Refer to the "Using the
CR8e" chapter – SAFTE Chain ID in the nStor CR8e User's Guide.)
