3.1.9 Switch connections: Power
Each DCX3000 Switch is supplied with a single power adapter but offers the facility to use a second input in order to provide
operational redundancy. The DCX3000 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 trans-
ferred to the other power adapter without a break in operation. Remote checking of the power inputs is possible at any time via
the Maintenance page of the browser interface.
There is no on/off switch on the DCX3000 unit, so operation begins as soon as power is applied at either port.
3.1.9.1 To connect the power adapter
1 Attach the output plug of the supplied power adapter to either power input socket on the left
side of the rear panel.
2 Connect the IEC connector of the supplied country-
specific 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.

3.1.9.2 To disconnect the power adapter
1 Isolate the power adapter from the mains supply.
Note: If you are replacing one of dual power adapters during opera-
tion, 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 module.
3 Gently pull the body of the outer plug away from the module. 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 modules and the 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 con-
tact with equipment whose surface temperature exceeds
40 degrees Centigrade.
Gently pull back the plug outer
body to release the lock
