2-1. Temperature
1. During installation and start-up of the CT system, it is imperative that adequate temperature checks be made
to assure that the environment meets specifications given. Excessive temperature when coupled with
reduced air flow if filters are clogged may over-stress components, causing subsequent failures.
2. Cooling requirements for the CPU subsystem are as follows:
Main computer Cabinet 17000 BTU/hr.
Disk Storage Unit (ZEBRA) 7500 BTU/hr.
DIsk Storage Unit (per ARGUS) 2050 BTU/hr.
Optional Aux Computer Cabinet 15000 BTU/hr.
FCO Optional Computer Cabinet
Even with adequate pre-installation planning and prior check-out of the air conditioning system, there will be
need for balance of the system to match the CT heat load.
