Connecting Power to the Switch
Caution: Use caution when removing an IOM on which you have optional PoE installed to avoid damaging the PoE module.
Precaución: Tenga cuidado al retirar un IOM que tenga un módulo PoE instalado, ya que éste puede dañarse.
4.Replace the slot’s coverplate.
Connecting Power to the Switch
You can install a single primary source of power or provide two sources of power for redundancy, as described in the following sections. Examples below illustrate connecting two power sources and assume two power supply modules have already been installed as described previously in “Installing a Power Supply” on page 2‐7.
Note: The two power supplies in the
To connect the G‐Series switch to one or two power sources, proceed as follows:
1.Plug a power cord into each switch AC power receptacle.
2.Plug the other end of each power cord into an appropriate, dedicated grounded AC outlet as follows.
•G3‐PWR‐POE requires a 20 Amp circuit.
•G3‐PWR requires a 15 Amp circuit.
Note: To take advantage of the load sharing and redundancy capabilities, each power cord must be plugged into a separate dedicated AC outlet.
3.Verify that the appropriate power LEDs (PWR1 and PWR2, not shown), located on the front panel, turn on as described in “Power LED Displays” on page 2‐12 and the SYSTEM LED turns red until the G‐Series completes its initialization.
If the initialization process is successful, the SYSTEM LED turns green. If the SYSTEM LED does not turn green, refer to Chapter 3 for troubleshooting information.
Power LED Displays
Once one or more power supplies are installed and power is connected to the switch, the power LEDs (PWR1 and PWR2) will indicate the switch’s power mode (redundant or additive) as follows:
Display | Status |
|
|
Off | Power supply not present. |
|
|
Green | Normal operation. |
|
|
Amber | Not enough power for redundancy. Operating in additive power mode. |
|
|
Red | Power failure. |

Refer to “Supported Power Configurations” on page 2‐6 for possible configurations in each power mode.
