1.3.1.1 Multiple Power Supply/Cooling Modules
The Galaxy 65 system must always be operated with two Power Supply/Cooling modules fitted. The two
Power Supply/Cooling modules operate together so that if one fails the other maintains the power supply
and cooling while you replace the faulty unit.
Module replacement should only take a few minutes to perform but must be completed within 5 minutes
from removal of the failed module.
1.3.2 Operators Panel
Supplied as an integral part of the Enclosure core product, a typical Operators (Ops) Panel is shown in
Figure 1–6.
The Ops Panel provides the enclosure with a micro controller which is used to monitor and control all
elements of the Enclosure.
1.3.2.1 Ops Panel Indicators and Switches
The Ops Panel includes Light Emitting Diodes (LEDs) which show the status for all modules, an Audible
Alarm which indicates when a fault state is present, a push-button Alarm Mute switch and a thumb wheel
SEL_ID address Range selector switch.
The Ops Panel switch functions are shown in Table 1–1.
Important Switch settings are only read at Power On.
The Galaxy 65 enclosure ID must always be set to select ID1.
