Service Clearances
When planning the location of the 45xx modular disk subsystem, consider the following:
•
The modular storage system occupies 67 centimeters by 89 centimeters (26 inches
by 35 inches) of floor space.
•
You must allow a clearance of at least 122 centimeters (48 inches) at the front and
rear of the modular storage system for adequate ventilation and for servicing. See
Figure 1-10.
•
The AC power cord measures 4.5 meters (15 feet).
•
The maximum fiber-optic connection for attaching the 45xx subsystem to a 6760
adapter in a Tandem host system is 2 kilometers (1.2 miles).
Note. Servicing is by replacement only. Access to components is from the front and rear
of a 45xx disk module. Disk drive CRUs are replaced from the front; BEBs, power
supplies, and fan CRUs are replaced from the rear.
