4.3 ISA Bus Expansion Chassis Configuration
The ISA bus expansion chassis provides a flexible capacity for adding voice modules of
varying types based on products from Dialogic. See Section 1.4 for a complete list of
available ISA bus expansion options.
Once the Dialogic voice modules are physically installed, you need to configure them by
running the ECU from the IP Platform console terminal. Use the ECU to register the modules
with the system hardware, and to reserve the addresses and interrupt request levels (IRQs)
that are to be used by the modules. The ECU attempts to identify and resolve resource
conflicts. The ECU may also be used to determine unused I/O ports, shared memory address,
and IRQs.
In addition to the Dialogic voice modules, other components within the ISA bus expansion
chassis include the:
•
Fan
•
Power supply
•
Alarm sensor module
•
Access I/O transceiver (AT bus expansion kit)
For a complete description of installing and configuring the voice-option modules, refer to the
Dialogic documentation shipped with the option.
For a complete description of removing and replacing the fan or power supply, refer to the I-
Bus 4820 User Manual that is shipped with your system.
Refer to Section 4.3.1 and Section 4.3.2 for complete descriptions of removing and replacing
the alarm sensor module and the AT bus expansion kit.
4.3.1 Removing and Replacing the Alarm Sensor Module
The alarm sensor module is mounted in the drive bay area of the ISA bus expansion chassis.
The 2T-IPSEN-AA alarm sensor module kit consists of an alarm sensor module, a cable to
connect the alarm sensor module to the rear bulkhead, and a cable to connect the rear
bulkhead to the alarm control module in the AlphaServer 1000A.
Perform the following procedure to remove the alarm sensor module:
1. Remove power from the ISA bus expansion chassis by pressing the On/Off switch on the
front of the ISA bus expansion chassis.
2. Remove the screws that secure the ISA bus expansion chassis to the front rails and extend
the ISA bus expansion chassis on the slides.
3. Remove the screws that secure the top cover and remove the top cover from the ISA bus
expansion chassis.
4. Disconnect the 6-pin bulkhead cable, the 4-pin power supply cable, and the 2-pin
temperature sensor cable from the alarm sensor module.
5. Remove the four screws that secure the alarm sensor module to the standoffs and remove
the alarm sensor module.
To replace the alarm sensor module, reverse steps 1 through 5 of the removal procedure.
