Juniper QFX5100, Hardware Manual

Page: 183 / 256

Optional equipment: Grounding cable kit with bracket, lug, and three nuts with integrated
washers.
WARNING: The 1 U models of the QFX5100 switch must be supported at all
four corners. Mounting the chassis using only the front brackets will damage
the chassis and can result in serious bodily injury.
CAUTION: All models of the QFX5100 require two people for installation. If
you are installing the QFX5100 switch above 60 in. (152.4 cm) from the floor,
you can remove the power supplies and fan modules to minimize the weight
before attempting to install the switch.
CAUTION: If you are mounting multiple switches on a rack, mount the switch
in the lowest position of the rack first. Proceed to mount the rest of the
switches from the bottom to the top of the rack to minimize the risk of the
rack toppling.
Four Post Procedure
To mount the switch on four posts in a rack using the provided mounting kit:
1.
Attach the ESD grounding strap to your bare wrist and to a site ESD point.
2.
Decide whether the Field Replaceable Unit (FRU) end of the switch or the port end is
to be placed at the front of the rack. Position the switch in such a manner that the
AIR
IN
labels on components are next to the cold aisle and
AIR OUT
labels on components
are next to the hot aisle.
3.
Align the holes in the mounting rail with the holes on the side of the chassis. See
Figure 32 on page 165 to see the proper alignment for the QFX5100-24Q model and
Figure 33 on page 166 for the alignment for the QFX5100-48S model and
Figure 34 on page 166 for the QFX5100-96S model.
