Chassis Lifting Guidelines for a QFX3500 Device
The weight of a fully loaded QFX3500 device chassis is approximately 30.8 lb (14 kg).
Observe the following guidelines for lifting and moving a QFX3500 device:
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.
•
Before installing a QFX3500 device, read the guidelines in “Site Preparation Checklist
for a QFX3500 Device” on page 45 to verify that the intended site meets the specified
power, environmental, and clearance requirements.
•
Before lifting or moving the QFX3500 device, disconnect all external cables.
•
As when lifting any heavy object, lift most of the weight with your legs rather than your
back. Keep your knees bent and your back relatively straight and avoid twisting your
body as you lift. Balance the load evenly and be sure that your footing is solid.
