Installation

To connect power to the switch:

1.Connect the power adapter or power cord to the switch using one of the following methods:

For the BayStack 70-8T 10/100 Ethernet Switch or BayStack 70-16T 10/ 100 Ethernet Switch, connect the DC power adapter to the power adapter receptacle on the rear panel of the switch. Then connect a standard power cord to the adapter.

Warning: Use only the power adapter that was shipped with your switch to supply power to that switch. Read the amperage label on the power adapter to be sure it is the correct adapter for your switch.

Do not use the 8-port adapter (5 V DC/3 Amp) with a 16-port switch. Do not use the 16-port adapter (5 V DC/4 Amp) with an 8-port switch.

For the BayStack 70-24T 10/100 Ethernet Switch, connect one end of the power cord to the power outlet on the rear panel of the switch.

2.Screw the plastic cable holder into the bottom of the switch, near the power receptacle.

3.Snap the power cord or power adapter cord into the cable holder to secure the cord to the switch.

4.Connect the other end of the power cord to a standard power supply.

The switch automatically selects the proper voltage in the range of 100 to 240 volts, and the Power LED lights. The switch is now operational.

Verifying Installation

When power is applied to the switch, power-on self-tests are run. You can verify proper orientation of the BayStack 70 Series 10/100 Ethernet Switch by observing the front panel LEDs.

Verify network communications by ensuring that all the necessary connections have been made, that all connected resources can be accessed, and that the LED indicators on the switch are functioning properly. For additional information, refer to Chapter 4, “Troubleshooting.”
