Third-party rack requirements
The DM5500 and optional expansion enclosures must be installed in a customer-provided rack that meets the following
requirements.
Table 13. Third-party rack requirements for the DM5500 and optional expansion enclosures
Requirement category Description
Rack The DM5500 and optional expansion enclosures fit in a standard rack with a minimum depth of
37 inches (940 mm).
Recommended 24 inches wide rack to provide room for cable routing on the sides of the rack.
If you install a front door, it must maintain a minimum of 1.2 inches of clearance to the bezels.
It must be perforated with 50% or more evenly distributed air opening. It should enable easy
access for service personnel and allow the LEDs to be visible through it.
If you install a rear door, it must be perforated with 50% or more evenly distributed air
opening.
Blanking panels should be used as required to prevent air circulation inside the rack.
There is a recommended minimum of 42 inches of clearance in the front and 36 inches of
clearance in the rear of the rack to allow for service area and proper airflow.
Power The customer-provided rack should have redundant power zones with separate PDU power
strips. Each redundant power zone should have capacity for the maximum power load. When
configured this way, the appliance will remain up and running even with the failure of one
power zone.
Use the power calculator to refine the power requirements based on the hardware
configuration and customer-provided PDU.
For customer-provided PDUs, the Dell power cables on the appliance have NEMA 5-15P
connections to the PDUs.
NOTE: Dell is not responsible for any failures, issues, or outages resulting from failure of
the customer-provided PDUs.
Weight
Customer rack and data center floor must be capable of supporting the weight of DM5500
equipment. The maximum weight of the DM5500 with all 24 drives installed is 43.2 kg (95.24
lb). The weight of each expansion enclosure is 25.6 kg (56.39 lb).
Use the power and weight calculator to refine the weight requirements based on the hardware
configuration and customer-provided rack and PDU.
