Before you begin, ensure that you have the following parts and tools available to mount
the device in a rack:
A mechanical lift with a load capacity of at least 750 lb (341 kg). If you do not have a
lift rated for 750 lb (341 kg), you must remove all components from the chassis and
use a lift rated for at least 250 lb (114 kg). The weight of an empty QFX3008-I
Interconnect device and midplane is approximately 205 lb (93 kg).
Phillips (+) screwdriver, number 2 or number 3, depending on the size of your rack
mounting screws, for mounting the device in a rack (not provided)
Mounting screws appropriate for your rack (not provided)
Rear support anchors to secure the chassis to the four-post mounting shelf and rear
support bracket (provided)
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)
