1 Measured with PICs installed in slots 1, 2, 5, 6a/7a, 7b, and 7c; PIC in slot 7c had two external connections. Sysex
was running. Fans were running at full speed.
2 Measured with 14 disk drives installed and active.
3 Maintenance switch has only one plug. If a UPS is installed in the modular cabinet, the maintenance switch plug
must be connected to the extension bars on the right side of the modular cabinet.

Altitude2
1. Operating and recommended ranges refer to the ambient air temperature and humidity measured 19.7 in. (50 cm)
from the front of the air intake cooling vents.
2. For each 1000 feet (305 m) increase in altitude above 10,000 feet (up to a maximum of 15,000 feet), subtract 1.5° F
(0.83° C) from the upper limit of the operating and recommended temperature ranges.
Nonoperating Temperature, Humidity, and Altitude
• Temperature:
— Up to 72-hour storage: - 40° to 150° F (-40° to 66° C)
— Up to 6-month storage: -20° to 131° F (-29° to 55° C)
— Reasonable rate of change with noncondensing relative humidity during the transition
from warm to cold
• Relative humidity: 10% to 80%, noncondensing
• Altitude: 0 to 40,000 feet (0 to 12,192 meters)
