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 the DC input circuit to a FES, FESX, or FWSX (DC power supply part number RPS5DC and
RPS-X424-DC), make sure there is a 10-amp listed 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, 14 AWG, marked
VW-1, and rated 90 degrees Celsius.
CAUTION:
For the DC input circuit to the system (DC power supply part number RPSDC-X424-POE), 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
minimum 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 RPS8-AC power supply is designed exclusively for use with the FES2402-POE and FES4802-
POE devices. The power supply produces extensive power to support 802.3af applications. Installing the power
supply in a device other than the FES2402-POE or FES4802-POE will cause extensive damage to your equip-
ment.
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.
WARNING:
Power supplies are hot swappable. However, Foundry Networks recommends that you disconnect
the power supply from AC power before installing or removing the supply. 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.
Otherwise, you could be injured or the power supply or other parts of the device could be damaged.
WARNING:
Make sure that the power source circuits are properly grounded, then use the power cord supplied
with the device to connect it to the power source.
WARNING:
If the installation requires a different power cord than the one supplied with the device, make sure
you use a power cord displaying the mark of the safety agency that defines the regulations for power cords in your
country. The mark is your assurance that the power cord can be used safely with the device.
