Figure 96 4U, 60 (2.5- or 3.5-inch) DAE (interior view)
The fan modules, disks, and LCCs shown in
are accessible only by sliding the
DAE out of the rack and sliding the top cover back (see
). The ICMs
and power supplies shown in
are accessed from the rear of the 4U DAE.
Access to the internal components in a 4U, 60 (DAE7S) enclosure mounted 31U (4.5 ft, or
1.38 m) or higher above the floor requires an appropriate EMC service ladder and is
restricted to authorized service personnel only. Attempts to service disks, fans, or other
DAE components mounted 31U or higher without a recommended EMC service ladder and
personnel may result in serious personal injury. If an EMC service ladder is on site, this
ladder is the property of EMC and is only available for use by authorized EMC service
personnel.
If installing a new 4U, 60 DAE or replacing an existing 4U, 60 DAE above 31U is necessary,
then an appropriate portable mechanical lifting device is required. For more information
about this type of device, see
“Appendix B: Field lift tool and accessory kit” on page 135
.
If replacing or adding a 4U, 60 (2.5- or 3.5-inch) DAE becomes necessary, a portable
mechanical lift is recommended by EMC. The portable lift commonly used by EMC service
personnel is manufactured by Alum-A-Lift. Included with the lift is a lift kit which provides
instructions for using the portable lift. For more information, refer to
tool and accessory kit” on page 135
