Service-clearance and floor-load requirements

This topic provides floor-loading strength and service clearances for the DS6000
series.
Clearances for the DS6000 models or expansion enclosure
For each DS6000 series model or expansion unit, service personnel must be able
to open the front and rear covers to perform service.
Service clearance refers to the empty space in front of, next to, or behind a storage
unit that a service person needs in order to access the unit. The service clearance
of adjacent units may overlap. Weight distribution areas that are required to handle
floor loading do not overlap.
Use the following minimum service clearances when planning the placement of your
system.
v At the front of the unit, allow a minimum of 121.9 cm (48-in.)
v At the rear of the unit, allow a minimum of 76.2 cm (30-in.)
v At each side of the unit, allow a minimum of 5.1 cm (2-in.)

Planning for environment requirements

Plan to locate your DS6000 series in a site that has the same environment for the
base unit and any expansion units.
Operating environment
Table 19 describes the environment operating requirements for the DS6800 (Model
1750-511). The 1750-EX1 expansion unit has the same environmental
requirements.

1. The upper limit of dry bulb temperature
must be de-rated (lowered) 1.0°C for
every 137 meters of elevation above 915
meters.
2. The upper limit of wet bulb temperature
must be derated (lowered) 1.0°C for
every 274 meters of elevation above 305
meters.
