When the Cisco ONS 15501's Ethernet port is connected to other Ethernet switches for network

management purposes, it is reco mmended that either end of the Ethernet port NOT be configured in

auto-negotiation mode, and that both ends of the Ethernet connec tion be configured in either 10 M bps

or 100 Mbps half or full duplex mode.

Note The 15501 default Ethernet boot mode is half-duplex 10 Mbps.

For additional in formation, pleas e refer to the ethmode command.

To configure the Cisco ONS 15501 for SNM P, follow these steps:

Step 1 Connect the CiscoONS 15501 to an Ethernet LAN using a standard RJ-45 cable.

Step 2 Enter add-snmp-mgr manager-ip to set the SNMP manager IP addresses. The maximum number of

SNMP manager IP addresses is 16.

Step 3 Enter get-snmp-mgr to display the list of SNMP managers.

Alarm Contact Closures

The CiscoONS 15501 provides a front panel, single form C, discrete external alarm output. (See the

“Cisco ONS 15501 Front Panel” section on page1-7 for additional information.) The exter nal alarm

output is through the eight wires of an RJ-45 connector.

The following events are reported by the discrete external alarms through i ndividual alarm contacts:

•Alarm 1—Loss of input signal or input signal power below threshold

•Alarm 2—Failure in the pump laser or pump laser temperature

•Alarm 3—Loss of input power supply or power supply out of range

•Alarm 4—Undefined (always on; may be used for power in dication)

Note The default state of the alarm contacts is Normally Closed. Depe nding on which fault conditio n occurs,

specific alarm contacts open. The corresponding Cisco ONS 15501 LEDs turn on/off. (See the “Cisco

ONS 15501 LED Alarm Definitions” section on page1-9 for additio nal information.)
