Power Supply Precautions

The following precautions apply to FastIron GS POE 48-port devices:

If your FastIron GS POE chassis has 48 ports and only one power supply, and each POE-enabled port needs 15.4 watts, then a maximum of 31 ports can supply power to connected devices.

If your FastIron GS POE chassis has 48 ports and two power supplies, and the POE ports are consuming more than 480 watts of power, a single power supply failure will cause both power supplies to shut down.

If your FastIron GS POE chassis has 48 ports and only one power supply, and the power consuming devices connected to POE-enabled ports consume a total of more than 480 watts of power, the power supply may shut down.

CAUTION: Use a separate branch circuit for each AC power cord, which provides redundancy in case one of the circuits fails.

CAUTION: Ensure that the device does not overload the power circuits, wiring, and over-current protection. To determine the possibility of overloading the supply circuits, add the ampere (amp) ratings of all devices installed on the same circuit as the device. Compare this total with the rating limit for the circuit. The maximum ampere rat- ings are usually printed on the devices near the input power connectors.

CAUTION: All devices with DC power supplies are intended for installation in restricted access areas only. A restricted access area is where access can be gained only by service personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for the location.

CAUTION: For a DC system (DC power supply part number RPSDC-FGS), use a grounding wire of at least 10 American Wire Gauge (AWG). The 10 AWG wire should be attached to an agency-approved crimp connector, crimped with the proper tool.

CAUTION: For the DC input circuit to the system (DC power supply part number RPSDC-FGS), make sure there is a Listed 30 amp circuit breaker, minimum -48Vdc, double pole, on the input to the terminal block. The input wiring for connection to the product should be Listed copper wire, 10 AWG, marked VW-1, and rated mini- mum 90 degrees celcius.

CAUTION: Make sure you insert the power supply right-side up. It is possible to insert the supply upside down, although the supply will not engage with the power backplane when upside down. The power supply is right-side up when the power connector is on the left and the fan vent is on the right.

CAUTION: Remove the power cord from a power supply before you install it in or remove it from the device. Otherwise, the power supply or the device could be damaged as a result. (The device can be running while a power supply is being installed or removed, but the power supply itself should not be connected to a power source.)

CAUTION: The FGS power supply is designed exclusively for use with the FGS devices. The power supply pro- duces extensive power to support 802.3af applications. Installing the power supply in a device other than the FGS will cause extensive damage to your equipment.

WARNING: Disconnect the power cord from all power sources to completely remove power from the device.

WARNING: Make sure to choose the appropriate circuit device depending on the number of AC power supplies installed in the chassis. The minimum current draw for the system is one AC power supply.
