• Alarm Out relay contacts (RJ-45)
• Alarm LEDs
• Serial interface (EIA/TIA-232)
• Serial interface connected to a modem
• LAN interface (RJ-45)
3.5.1 Alarm Out Relay Interface (RJ-45)
The ONS 15216 EDFA2 Alarm Out (RJ-45) port reports alarm status for the following:
• Loss or degradation of electrical power
• Laser pump overheating or excessive pump current, output power, gain, and case temperature
• Loss or degradation of optical network
These alarms can be connected to a network operations center (NOC) network management system
(NMS) using the following methods:
• Cisco ONS 15454 miscellaneous discrete input
• Central Office alarm panel/system
Table 3-2 provides the ONS 15216 EDFA2 RJ-45 alarm out pinout and alarm definitions.
