In addition to the front panel connectors, the Host I/O module contains three
passive differential SCSI bus terminators that terminate the SCSI bus from the
host system. Termination is automatically disabled when a cable is connected
to the Host Out connector. The UPS serial connector on the host I/O module
(designated CTR 0 and CTR 1) provides shelf status information to the UPS.

NOTE:

If you have only one SCSI cable connection to the host I/O module, you must

connect the cable to the Host In connector. Do not use any external bus termination. The
Host Out connector on the module is used for mid-bus connections in a multiple-host
system configuration.

Shelf Cooling

The device I/O module ensures that the SBBs and controller shelf are at the
proper operating temperature by monitoring the operational status of the
blowers and sensing the ambient air temperature.

The two dual-speed blowers cool all the shelf components by drawing ambient
air in through the front of the SBBs and exhausting it out the rear of the
controller shelf. The blowers normally operate at low speed. Reduction of the
airflow through the shelf or an increase in the ambient temperature may result
in overheating, causing component failure or data corruption.

The device I/O module ambient temperature circuitry monitors the air flowing
through the module. If the ambient temperature exceeds 90ºF + 36ºF
(32ºC + 2ºC), the circuitry:

■

Turns on LED for both blowers.

■

Causes both blowers to switch to the high-speed mode to increase
airflow through the shelf.

When the I/O module circuitry detects a blower that is not operating or not
operating at the correct RPM, this circuitry:

■

Turns On an LED on the I/O module front panel that identifies the
defective blower.

■

Causes the operational blower to switch to the high-speed mode to
increase airflow through the shelf, thereby maintaining the proper
operating environment.

NOTE:

The controller shelf power supply-status LEDs also display blower error

conditions. However, they do not identify the defective blower, nor do they report ambient
air temperature faults.
