HP Netserver L Server series - Manual (Page 65)

Chapter 8 Mounting the NetServer in a Rack
57
CAUTION Both rack types feature an anti-tip foot which must be
extended out the front to prevent rack tip-over. See
Figure 8-12. You can tell the front from the rear (for both
types of rack) by the overhanging top panel at the rear
of the rack.
3. Prepare to lift the server into the rack. To do so, extend the anti-tip foot
from the front of the rack, then remove power supplies from the server to
reduce the total weight to be lifted. See Figure 8-13.
4. Using two people, grasp the handles and lift the HP NetServer LH 3r.
Move the server in between the extended slide members. Position the
server so it is supported by the handles resting on the extended slide
members.
