6. When power is connected, verify that the SYS LED on the port extender turns green.
Connecting the V300 Virtual Port Extender to Power
V300-8P-2W and V300-8T-2W models run on AC power with included power supply unit(s).
V300HT-8P-2W and V300HT-8T-2W models can run on redundant power supplies (RPS). HT model
power supplies are sold separately.
See the following topics to connect non-PoE V300 models to power:
•
Connect the V300 to a Primary Power Source on page 107
•
Connect the V300 to a Redundant Power Source on page 107
Connect the V300 to a Primary Power Source
Note
Installing the system as described in this guide meets the protective earth grounding
requirements of the National Electrical Code (NEC) UL 60950 and IEC 60950 standards.
However, in some cases, it may be necessary to use an alternative grounding method. In these
cases, a 14 AWG wire can be connected between the grounding lug on the chassis and a
nearby building ground point.
To attach the V300 switch to a power source, do the following:
1. Connect the PSU to the V300 with the integrated power cable.
2. Connect the AC power cord to the AC power input socket on the power supply and plug the other
end into an AC power outlet.
To attach the V300HT model to a primary power source, do the following:
3. Connect the PSU to the included screw terminal connector (use adequate AWG wire for DIN PSUs).
4. Plug the screw terminal connector into the port extender DC input (PSU1 recommended).
5. Connect the:
•
AC power cord to the AC power input socket on the PSU and plug the other end into an AC
power outlet for non-DIN PSUs; or
•
PSU to an AC power source using the instructions included with the PSU for DIN PSUs.
When power is connected, verify that the PWR LED on the switch turns green. If the PWR LED does not
turn green, verify that the power source is powered on and the connection was made properly.
