CAUTION
The power supply is designed exclusively for use with the ExtremeSwitching CES Series and ExtremeRouting CER Series
devices. The power supply produces extensive power. Installing the power supply in a device other than an
ExtremeSwitching CES Series or ExtremeRouting CER Series will cause damage to your equipment.
DANGER
Disconnect the power cord from all power sources to completely remove power from the device.
DANGER
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.
DANGER
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.
DANGER
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.
CAUTION
All devices with DC power supplies are intended for installation in restricted access areas only. A restricted access area is a
location where access can be gained only by trained 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, (DC power supply part number RPS9-DC), make sure there is a 20-amp circuit breaker, minimum
-48VDC, double pole, on the input to the terminal block. The input wiring for connection to the product should be copper
wire, 12 AWG, marked VW-1, and rated 90 degrees Celsius.
CAUTION
For a DC system, use a grounding wire of at least 6 American Wire Gauge (AWG). The 6 AWG wire should be attached to an
agency-approved crimp connector crimped with the proper tool. The crimp connector should allow for securement to both
ground screws on the enclosure. For the Ground lug, use UL listed Panduit crimp connector, P/N LCD6-10A, and two
10-32, PPH, screws to secure crimp connector to chassis. Grounding position is located on the side of the chassis
adjacent ground symbol.
