SentinelRAID 170 Installation and Hardware Reference Manual

NOTE:

It is recommended to use the embedded terminators on host or drive channels by setting DIP switches, and then installing an external terminator on the other end of your SCSI cable. If a drive fails, data traffic will remain unaffected. Please note of the following:

1.Refer to the installation documents that came with your drives for information on jumper settings.

2.Set a unique SCSI ID address on each drive. Avoid ID 7 – this is a default reservation for the controller. In redundant controller mode, each of the two controllers takes an ID on each SCSI bus. The combination can be ID 6 and ID 7 or ID 8 and ID 9.

4.4.1Power Connection

The power input and connection of the controller is exactly the same as those for hard disk drives. Be sure to connect both connectors. The power connection is shown in Figure 4-4below.

4.4.2 Connecting RS-232C Terminal Emulation

The controller can be configured via a PC running a VT-100 terminal emulation program or a VT-100-compatible terminal. The provided combo cable (IFT-9512) converts the RS-232 signals from the 20-pin header into the two 9-pin D-Sub male connectors. The pin layout of the 9-pin connectors is similar to that of a PC’s serial port and is set as a DTE device. Proper cable connection is displayed in the following diagram. The DB-9 connectors of the IFT-9512 cable are marked as “COM 1” and “COM 2.” Please use the connector marked as “COM 1” for terminal emulation.

Connect COM 1 to the included null modem (IFT-9011) and connect the other end of the null modem to the outside of your enclosure or to an external RS-232 cable. COM ports can also connect to a modem for remote configuration. COM 2 cannot be used to download firmware.
