Juniper QFabric QFX3008-I, Manual, Page: 262 / 472

To mount the QFX3008-I Interconnect device in a rack using a mechanical lift (see Figure
62 on page 237 ):
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
spacer bars installed in the rack ensure that the holes in the front-mounting brackets
align with the holes in 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.
5.
Move the lift away from the rack.
6.
Ensure the mounting brackets are flush with the front of the rack.
7.
Install a mounting screw into each of the open front-mounting holes aligned with the
rack, starting from the bottom.
8.
Visually inspect the alignment of the device. If the device is installed properly in the
rack, all the mounting screws on one side of the rack are aligned with the mounting
screws on the opposite side, and the device is level.
9.
After ensuring that the device is aligned properly, tighten the screws.
