To prevent bodily injury when mounting or servicing the 4U, 60 DAE in a Dense rack, you
must take special precautions to ensure that the DAE remains stable. The following
guidelines are provided to ensure your safety:
1. When lifting this DAE, always use two people and a lifting device.
2. For service personnel, when accessing this unit in a rack above 31U, always use an
EMC authorized step ladder.
3. When mounting this unit in a partially filled rack, load the rack from the bottom to the
top with the heaviest component at or close to the bottom of the rack.
4. If the rack is provided with stabilizing devices, install the stabilizers before mounting
or servicing the DAE in the rack.
To gain access to the DAE, you must first, open the console, then unlock and remove the
front bezel. Next, to unlock the DAE from the rails, pull on the orange loops (see location 1
in Figure 104) on each side of the DAE. Finally, pull the orange tabs (see location 2 in
Figure 104) on each side of the DAE to slide the DAE out of the rack on its rails until it
locks into the secure service position. For complete instructions, see the
in a 60-disk enclosure
procedure available online at https://mydocs.emc.com/VNX/and
go to VNX Tasks, then select Replace VNX hardware. Next, follow the steps in the wizard.
