2.4. Connecting Power
This section describes connecting power to the SG4500 Series. Only an AC power source is
supported by the product.
Important
Please read the advisory information concerning electrical safety in Chapter 6, Safety
Precautions .
With the SG4500 Series there are double, hot-swappable PSUs and no On/Off switch. Power
becomes available to the whole appliance as soon as it is made available to any of the installed
PSUs. The back of the SG4500 Series is shown below with the two PSUs visible on the far left.

CorePlus will boot-up as soon as power is available to the appliance.
Operating the SG4500 Series with a Single PSU
The dual PSUs on the SG4500 Series provide power supply redundancy in the case of a single
PSU failure. However, the SG4500 Series can operate correctly with only one power supply fitted.
If a second PSU is not fitted then the second PSU slot must be filled with a special
PSU Filler
Module component. The filler module is necessary to prevent the alarm sounding because the
hardware will detect only one active PSU.
It does not matter which of the two SG4500 Series PSU slots is fitted with the PSU and which is
fitted with the filler module. It should also be remembered that the CorePlus
hardware
monitoring feature will consider a missing PSU to be a malfunctioned PSU and any CorePlus
Hardware Monitoring alarms should be adjusted accordingly.
Connecting AC Power
To connect power, follow these steps:
1. Plug one end of the power adapter's power cord into the power receptacle on the back
panel of the SG4500 Series. For the SG4500 Series, there can be two hot-swappable power
supplies so the supplied power cords should be used to connect the both PSUs if two are
installed.
2. Plug the other end of the power cord into a grounded power outlet.
3. With the SG4500 Series, the system starts as soon as the PSUs are connected to a power
source and the power is applied.
