(295 kg). Observe the following guidelines for lifting and moving the device:
•
Before moving the device to a site, ensure that the site meets the power, environmental,
and clearance requirements specified in the “Site Preparation Checklist for a QFX3008-I
Interconnect Device” on page 84.

Do not attempt to lift the QFX3008-I Interconnect device by yourself. We recommend
using a mechanical lift rated for at least 750 lb (340.2 kg) to install the QFX3008
device in a rack or cabinet. 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).
