Cisco Systems Gateway 10 Powering on the Cisco RF Gateway, Verifying Basic System Power

5Powering on the Cisco RF Gateway 10

After all network interfaces and coaxial cables are connected, perform a visual check of all connections and ensure the following:

•All captive screws on all line cards and modules should be tightened to 6-8 in-lbs.

Note The system will not power on unless the captive screws on the DC PEM are fully engaged.

•The ejector levers on every card are in the locked position.

•All the cables are connected (power, data link, network, Ethernet).

Note The system will not power on correctly unless both power inputs (Input 1, Input 2) are connected to the external power source.

•The console terminal or modem is cabled and turned on.

•A compact flash card is installed in the supervisor card.

You are now ready to power on the system for the first time using the following procedure.

Step 1 Verify that each DC PEM is turned off (0).

Step 2 Remove the tape from the circuit breaker switch handle.

Step 3 Turn on power at the power supply that is suppling the DC power for the chassis.

Verifying External DC Power Source Connections

After turning on the external DC power source, verify that –48V1 and –48V2 LEDs are green (all other LEDs on the PEM should be off). If either of these LEDs is off or the FAULT LED is red, proceed as follows:

Step 1 Turn off the external DC power source.

Step 2 Verify that the wiring from the external power source to the two power inputs (Input 1and Input 2) is connected correctly.

Step 3 Measure the input voltage from the external power source at the –48 V1 and –48 V1 RTN terminals.

Verifying Basic System Power

•Before the chassis power is turned on, the –48V1 LED and –48V2 LED should be green. This indicates that both DC inputs for each PEM are wired correctly to the external power source.

•Power on the chassis by switching the PEM breaker switch to the on position. At this point the OUTPUT OK LED on the DC PEM should be green.

•The fan assembly should turn on. When power is provided to the chassis, the fans in the fan assembly module initially operate at high speed. If all four fans are operating correctly, and if the temperature of the chassis is in the nominal operating range, the fans slow down to their normal operating speed.

•The OK LED on the fan assembly module should be green, indicating that all fans in the blower are operating properly. You should be able to feel the air blowing out of the upper rear of the chassis.
