The Switch zl Internal Power Supply does not have a power switch. It is
powered on when the power cord is connected to the supply and to a power
source.
Please see the "Installation Cautions" on
5.
Verify the power supply is installed correctly by checking the LEDs
on the front of the switch. The following example shows a Series 5400zl
Switch.

Figure 5.
Switch Power Status and Fault LEDs
The Power Status LED for the power supply you have just installed will be
flashing simultaneously with the Fault LED until that new power supply is
connected to an AC power source. Once it is connected to AC power, the
Power Status LED will be on continuously and not flashing, and the Fault LED
will stop flashing.
If the Power Status LED and the switch Fault LED continue flashing after the
power supply is connected to AC power, see "Troubleshooting" on the next
page.
