If you are using a redundant or external DC power supply, such as the Dell
Networking RPS720 or Dell Networking MPS1000, connect the DC power
cable to the DC receptacle located on the back panel. In Figure 1-11 on
page 23, the redundant power supply feed is in the middle and is labeled
RPS.

When the power is turned on with the local terminal already connected, the
switch goes through a power-on self-test (POST). POST runs every time the
switch is initialized and checks hardware components to determine if the
switch is fully operational before completely booting. If POST detects a
critical problem, the program flow stops. If POST passes successfully, valid
firmware is loaded into RAM. POST messages are displayed on the terminal
and indicate test success or failure. The boot process runs for approximately
60 seconds.
You can invoke the
Boot
menu after the first part of the POST is completed.
From the
Boot
menu, you can perform configuration tasks such as resetting
the system to factory defaults, activating the backup image, or recovering a
password. For more information about the
Boot
menu functions, see the
CLI
