Chassis Lifting Guidelines for a QFX5100 Switch
The weight of a 1 U fully loaded QFX5100 switch chassis is approximately 30.8 lb (14 kg);
the 2 U product SKU is approximately 32 lbs (14.5 kg). Observe the following guidelines
for lifting and moving a QFX5100 switch:
CAUTION: If you are installing the QFX5100 switch above 60 in. (152.4 cm)
from the floor, either remove the power supplies, fan modules, and any
expansion modules before attempting to install the switch, or ask someone
to assist you during the installation.
•
Before installing a QFX5100 switch, read the guidelines in “Site Preparation Checklist
for a QFX5100 Switch” on page 43 to verify that the intended site meets the specified
power, environmental, and clearance requirements.
• Before lifting or moving the QFX5100 switch, 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.
