Figure 41- Main Page Equipment Status
Check the current status of each component as follows:
1. Update Topology view:
a. Click Re-Discover: If new equipment (eg. Remote Node) has been added but does not yet
show up in the topology view
b. Click Refresh: If all components appear and to ensure current status is reflected
2. Review HU status indicators:
a. All OK: Component LEDs in the HU shelf indicate green state
b. Error/alarm: Component LEDs are flashing red, and a red “balloon” is present
3. Review Remote Node status indicators:
a. All OK: Component LEDs in the Remote Node indicate green state
b. Error/alarm: Component LEDs are flashing red, and a red “balloon” is present
If components appear with error conditions please see sections 5.3.3.1Optical Link Alarms and 5.5
Monitoring for details on error conditions.
5.3.2.2 Verify Optical Power Levels
The optical power levels at both ends of the fiber link (at the FIU of the Host Unit, and the CM of the Remote
Node) can be observed and verified through the EMS Local GUI.
Check optical power levels at the Host Unit as follows:
1. Click on the FIU in the topology diagram and the component window will pop up on the right as
shown in Figure 45- FIU Optical Power Levels.
2. Optical Transceiver 1 Tx Power: the output power of the FIU 1 to the fiber.
a. Nominal value is: +4.0 dBm +/-1.5 dB (impacted by temperature)
3. Optical Transceiver 1 Rx Power: the input power of the FIU 1 from the fiber.
a. Acceptable range is:-15 dBm ~ +6dBm (impacted by fiber loss)
4. Optical Transceiver 2Tx Power: the output power of the FIU 2 to the fiber.
a. Nominal value is: +4.0 dBm +/-1.5 dB (impacted by temperature)
5. Optical Transceiver 2 Rx Power: the input power of the FIU 2 from the fiber.
a. Acceptable range is: -15 dBm ~ +6dBm (impacted by fiber loss)
