3.2.1 Power Connection
Make sure you are using the correct power source and that no objects obstruct the airflow of the
fans.
The Switch uses two power supply modules, one of which is redundant, so if one power module fails
the system can operate on the remaining module.
Rear Panel Power Connection
Connect one end of the supplied power cord or power adaptor to the power receptacle on the back
of the Switch and the other end to the appropriate power source.
For the GS1900-8HP, GS1900-16 and GS1900-24E, use the POWER ON/OFF switch to have the
Switch power on or off.

a rack.
Note: Use the included power cord for the AC power connection.
1 Connect the female end of the power cord to the AC power socket.

Disconnecting the Power
The power input connectors can be disconnected from the power source individually.
