Starting the Switch
• The rack must be close enough to the dedicated power source so that you can connect the switch to the
• You have a designated power cable for each power supply that you are connecting to the dedicated
• The switch is not connected to the network (this includes any management or interface connections).
• The fan and power supply modules are fully secured in their chassis slots.
• Ensure that the switch is adequately grounded (see
Step 1 For each AC power supply, do the following:
a) Using the recommended AC power cable for your country or region, connect one end to the AC power supply.
b) Connect the other end to the AC power source.
Step 2 For each DC power supply, do the following:
a) Turn off the circuit breaker for the power source to avoid an electrical shock hazard.
b) Verify that the power cable wires from the power source are connected to a connector block.
If the positive, negative, and grounding wires from the power source are not connected to the connector block, see
Wiring a 48 V DC Electrical Connector Block, on page
c) Insert the connector block into the receptacle on the power supply. Make sure that the connector block clicks when
fully inserted in the receptacle and does not pull out.
d) If there is a safety cover for the terminals, place it over the terminals to avoid an electrical shock hazard.
e) Turn on the power at the circuit breaker for the DC power source.
Step 3 For each HVAC/HVDC power supply, connect it 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.

an optional jumper power cord to connect the switch to your outlet receptacle.
All of the fan slots must be filled with fan modules. The power supply slots must have at least one power
supply. If there is an open power supply slot, it must have a blank filler plate installed to preserve the
designed airflow.
