Juniper QFX3000-G QFabric, Deployment Manual, Page: 240 / 652

•
Eight screws to secure the chassis and rear installation blades to the rack (not provided).
• Appropriate screwdriver for the mounting screws (not provided).
WARNING: The QFX3500 device 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: If you are installing the QFX3500 device above 60 in. (152.4 cm)
from the floor, you must remove the power supplies, fan trays, and
management board before attempting to install the device, or ask someone
to assist you during the installation.
CAUTION: If you are mounting multiple devices on a rack, mount the device
in the lowest position of the rack first and proceed to mount the rest of the
devices from bottom to top.
To mount the device on four posts in a rack:
1.
Attach the ESD grounding strap to your bare wrist and to a site ESD point.
2.
With two mounting screws—and cage nuts and washers if your rack requires
them—attach one of the rear installation blades to the rear of the rack at the point
where you want to mount the device. Tighten the screws. The blade helps support
the rear of the chassis. You install the second rear installation blade after securing
both front mounting brackets. See
Figure 50 on page 214 .
