Chapter 1 – Introduction
Rear View
All ports are located on the rear panel of the
controller.
There are four SCSI connectors, allowing the
controller to be set up with two hosts and two
disk channels, or a single host and three disk
channels.
The Hot Plug connector is for optional
connection to a hard disk backplane.
The Combo connector is for the insertion of
the combo cable introduced below.
The Power connector fits a standard hard
drive power cable head.
Supplied accessories
3-in-1 Combo Cable
The combo cable includes the following connectors:
An RS232 connector to link to the host terminal COM port enabling use of the
monitor utility
A modem connector enabling the automatic dispatch of alert faxes
A monitor connector enabling various monitoring facilities. The default pin
assignments are:
Pins 1+3: Fan failure
Pins 2+4: Temperature failure
Pins 5+7: Power source failure
Pins 6+8: UPS warning
Pins 9 and A are unassigned
RS232 Connection for VT-100/ANSI Terminal-Emulation
The ACS-9910 controller can be configured via a PC running a VT-100 or ANSI
terminal-emulation. In order to connect to a PC, you need to connect an additional interface
cable to the extension cable, which converts the RS-232 signal of the 10-pin header
connector into a 9-pin D-sub male connector. The pin-layout of the 9-pin D-sub male
connector is similar to that of a PC's serial power and is set as a DTE device.
