DC circuit to the OFF position.
5. Remove the power source cable from the power supply faceplate:
•
AC power supply—Remove the power cord from the power supply faceplate by
detaching the power cord retainer and gently pulling out the female end of the
power cord connected to the power supply faceplate.
•

source cables to the power supply using the screwdriver, and remove the power
source cables from the power supply. Replace the screws on the terminals and

Removing a QFX3500 Device from a Rack or Cabinet
If you need to relocate an installed QFX3500 device, use the procedure described in this
topic. (The remainder of this topic uses “rack” to mean “rack or cabinet.” )
NOTE: When you remove multiple devices from a rack, remove the device in
the top of the rack first and proceed to remove the rest of the devices from
top to bottom.
Before removing a QFX3500 device from a rack:
•
Ensure that the rack is stable and secured to the building.
•
Ensure that there is enough space to place the removed QFX3500 device in its new
location and along the path to the new location.
•
Read “General Safety Guidelines and Warnings” on page 169.
•
Ensure that the QFX3500 device has been safely powered off (see “Powering Off a
QFX3500 Device” on page 143) and that you have unplugged (disconnected) the power
cords.
•
Ensure that you have disconnected any cables or wires attached to the QFX3500
