Starting the Switch
• Verify that all of the fan and power supply modules are installed in the chassis. If the chassis has only
• If you are using a DC power source, verify that the circuit is shut off at a circuit breaker.
Step 1
If the switch has AC power supplies, connect those power supplies to an AC power source as follows:
a) Verify that the AC power source is turned off at the circuit breaker.
b) Plug the power cable into the power receptacle on the power supply.
c) Attach the other end of the power cable to the AC power source.
d) Turn on the power at the circuit breaker.
e) Verify that the power supply is functioning by making sure that the OK LED turns green and the FAULT LED is
off.
Step 2 If the switch has HVAC/HVDC power supplies, connect those power supplies to a power source as follows:
a) Using the recommended high voltage power cable for your country or region, connect the Anderson Power Saf-D-Grid
connector on the power cable to the power receptacle on the power supply. Make sure that the connector clicks when
fully pushed into the receptacle.
b) Connect the other end of the power cable to a power source.
• When connecting to an HVAC power source, insert the C14 or LS-25 plug in a receptacle for the HVAC power
source.
• When connecting to an HVDC power source, do the following:
1. Verify that the power is turned off at a circuit breaker for the power source terminals.
2. Remove the nuts from each of the terminal posts for the power supply.
3. Place the power cable negative-wire terminal ring on the negative terminal for the power source and secure
them with a terminal nut.
4. Place the power cable positive-wire terminal ring on the positive terminal for the power source and secure
them with a terminal nut.
5. Place the power cable ground-wire terminal ring on the ground terminal for the power source and secure
them with a terminal nut.
6. If there is a safety cover for the power source terminals, place and secure it over the terminals to avoid an
electrical shock hazard.
7. Turn on the power at the power source circuit breaker.
Step 3 If the switch has DC power supplies, connect those power supplies to a DC power source as follows:
a) Verify that the DC power source is turned off at the circuit breaker.
b) Remove the clear plastic safety cover that prevents you from touching the negative (-) and positive (+) terminals on
the power supply.
c) Connect a negative cable from the power source to the left (-) terminal on the power supply.
d) Connect a positive cable from the power source to the right (+) terminal on the power supply.
e) Clip on the clear plastic safety cover over the power supply terminals to prevent accidental touching of these terminals.
f) Turn on the power at the circuit breaker.
