Technical Specifications and Operating Limits
Operating Limits
The ambient temperature specification is measured at the front door
inlet. The site must have air conditioning of the correct size and
placement to maintain the specified ambient temperature range. The
air conditioning must be able to handle the BTU requirements of the
DPEs.
The operating limits listed above for temperature and humidity must not be
exceeded inside the closed cabinet in which the DPE and any DAEs are
mounted. Mounting equipment in a cabinet directly above or below a DPE
does not restrict air flow to the DPE because air flows through the DPE from
front to back. Cabinet doors must not impede the front-to-back air flow.
Requirement Description
Ambient temperature 10°C to 40°C (50°F to 104°F)
Temperature gradient 10°C/hr (50°F/hr)
Relative humidity 20% to 80% noncondensing
Elevation 2438 m (8,000 ft) at 40°C; 3077 m (10,000 ft) at 37°C
Drive module power 25 W drive slot maximum (seeking)
