Four Post Procedure - Juniper QFX10002 Hardware Manual

• Management host, such as a PC laptop, with a serial port (not provided).
Optional equipment: Grounding cable kit with bracket, lug, and three nuts with integrated washers.
WARNING: QFX10002 devices must be supported at all four corners for four-post
installations. Mounting the chassis using only the front brackets will damage the chassis
and can result in serious bodily injury.
CAUTION: QFX10002 switches require at least three people for installation, two
people to lift the switch into place and another person to attach the switch to the rack.
You can remove the power supplies and fan modules to minimize the weight before
attempting to install the switch. If you are installing the QFX10002 device above 60 in.
(152.4 cm) from the floor, we recommend using a mechanical lift for over head
installation.
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 OUT labels on
components are next to the hot aisle.
3. Using a Philips screwdriver, remove the six screws on each side of the chassis that holds the cover
to the chassis. See Figure 33 on page 103
Figure 33: Removing the Screws Holding the Cover
for the location of these screws. Set the screws aside.
