Power connections
The CCS-PRO4 switch is supplied with a single power adapter but offers the facility to
use a second input in order to provide operational redundancy. The CCS-PRO4 unit can
operate perfectly well from a single power adapter operating alone. When two adapters
are connected, the unit will spread its load between them; should one power input fail,
100% of the load will be transferred to the other power adapter without a break in
operation. Remote checking of the power inputs is possible at any time via the browser
interface - see Status page for details.
There is no on/off switch on the CCS-PRO4 unit, so operation begins as soon as power
is applied at either port.
To connect the power supply
1 Attach the output connector of the supplied power
adapter to either of the two power input sockets
on the left side of the rear panel.
2 Connect the IEC connector of the supplied country-specic power cord to the socket
of the power adapter.
3 Connect the power cord to a nearby main supply socket.
4 Where power redundancy is required, repeat steps 1 to 3 for a second power adapter.
To disconnect a power adapter
1 Isolate the power adapter from the mains supply.
Note: If you are replacing one of dual power adapters during operation, it is not necessary to
also remove power from the other adapter.
2 Grasp the outer body of the power adapter plug where it connects with the CCS-
PRO4 unit.
3 Gently pull the body of the outer plug away from the switch. As the body of the plug
slides back, it will release from the socket and you can fully withdraw the whole plug.
IMPORTANT: Please read and adhere to the electrical safety information
given within the Safety information section of this guide. In particular, do not use
an unearthed power socket or extension cable.
Note: Both the switch and its power supplies generate heat when in operation and will become
warm to the touch. Do not enclose them or place them in locations where air cannot circulate
to cool the equipment. Do not operate the equipment in ambient temperatures exceeding
40 degrees Centigrade. Do not place the products in contact with equipment whose surface
temperature exceeds 40 degrees Centigrade.
