EMC VNX5400 Hardware Information Guide 69
Disk-array enclosures
This section describes and illustrates the front- and rear-panel controls, ports, and LED
indicators on the disk-array enclosures (DAEs) supported on the VNX5400 platform.
IMPORTANT
DAE configuration rules:
1.) Maximum number of enclosures per bus is 10.
2.) Maximum number of drives per bus is 250.
3.) Consider the maximum number of drives supported by the storage system model.

Lifting the DAE and installing it into or removing it from a rack is a two- to three-person
job. If needed, use an appropriate lifting device (portable mechanical lift). A fully loaded
2U, 25 DAE; 3U, 15 DAE; 3U, 120 DAE; or 4U, 60 DAE weighs approximately 45 lb (20.41
kg), 68 lb (30.84 kg), 165 lb (74.8 kg), or 213 lb (96.62 kg), respectively.
Because the 3U, 120 and the 4U, 60 DAEs are extremely heavy, EMC recommends a
portable mechanical lift manufactured by Alum-A-Lift. For more information about the
EMC recommended portable mechanical lift and an example illustration depicting the lift,
go to “Appendix B: Field lift tool and accessory kit” on page 135.

Access to the internal components in a 3U, 120 (DAE8S) or a 4U, 60 (DAE7S) enclosures
mounted 31U (4.5 feet, or 1.38 meters) or higher above the floor requires an appropriate
lifting device (portable mechanical lift) and is restricted to authorized service personnel
only. Attempts to service disks, fans, or other DAE components mounted 31U or higher
without a portable mechanical lift and personnel may result in serious personal injury.
For more information about the weight and dimensions of a VNX5400 platform DAEs, go
to https://mydocs.emc.com/VNX/ and go to the About VNX section, then select View
technical specifications. Next, follow the steps in the wizard.
The VNX5400 platform supports the following four types of DAEs across a 6-Gb/s SAS
bus:
“2U, 25 (2.5-inch) DAE (DAE5S)” on page 73
“3U, 15 (3.5-inch) DAE (DAE6S)” on page 81
“3U, 120 (2.5-inch) DAE (DAE8S)” on page 90
“4U, 60 (2.5- or 3.5-inch) DAE (DAE7S)” on page 107
