WARNING!
Always be sure that the 1200 W DC PSU does not have the input cabled connected at any time when the DC PSU
is not installed in the switch. Do not remove the DC PSU from the switch before disconnecting the input DC cable
from the PSU.
5 Pull the handle of the PSU to disconnect the PSU from the power connector at the back of the power
supply bay. Slide the PSU partway out of the bay.
6 Wearing thermal protective gloves, place both hands underneath the PSU to support the weight as it
is pulled out from the switch.
To remove additional 1200 W DC PSUs, repeat steps 2 through 6.
