NOTE: Earlier versions of the four-post rack mounting hardware did not
require the rear support anchors. If your four-post rack mounting hardware
includes spacer bars and two shelves the rear support anchors are not
required.
• Four screws, two UNC 1/4-20 (right side) screws and two M6 (left side) screws, to
secure the rear support anchors to the chassis (provided)
To mount the QFX3008-I Interconnect device in a rack using a mechanical lift (see
Figure 26 on page 173 and Figure 27 on page 174 ):
1.
Load the device onto the lift, making sure it rests securely on the lift platform.
2.
Using the lift, position the device in front of the rack, centering it in front of the mounting
shelves installed in the rack.
3.
Lift the chassis approximately 0.75 in. (1.9 cm) above the surface of the mounting
shelves. Position the chassis in the rack as close as possible to resting on the support
that the mounting shelves provide.
4.
In a four-post rack, carefully slide the device onto the mounting shelves until the
front-mounting brackets (“ears”) attached to the chassis contact the rack rails. The
handles on the side of the chassis can be used to help position the Interconnect device
in the rack.
In a two-post rack, carefully slide the device onto the mounting shelves until the
center-mounting brackets (“ears”) attached to the chassis contact the rack rails. The
handles on the side of the chassis can be used to help position the QFX3008-I
Interconnect device in the rack.
