Configuring EPON PoE
EPON PoE overview
On an OLT, you can remotely configure PoE for ONUs.
As shown in Figure 1, the PoE model of the EPON system includes the following elements:
· PSE—A power sourcing equipment (PSE) is an ONU that supplies power to PDs through UNIs.
· PD—A powered device (PD) receives power from a PSE. PDs include IP telephones and APs.
Restrictions and guidelines: EPON PoE configuration
In an EPON system, support of ONUs for EPON PoE varies by ONU model and software version.
EPON features are supported only on the default MDC. For more information about MDCs, see Virtual Technologies Configuration Guide.
You can configure PoE for UNIs by using the onu poe command series and the uni poe command series. On the same ONU interface or RONU interface, the onu poe command series and the uni poe command series for configuring the same feature are mutually exclusive.
· To configure PoE with the same parameters on all UNIs of an ONU, use the onu poe command series.
· To configure PoE on only some UNIs of an ONU or configure PoE with different parameters on UNIs of an ONU, use the uni poe command series.
· To switch the current commands series to the other command series, use the undo forms of the current command series to cancel the configuration first.
When the sum of power supplied to all PDs connected to UNIs of an ONU exceeds the maximum power of the ONU, the ONU might disable PoE for some UNIs to avoid power overload. As a best practice, use the alarm enable onu power-alarm command to enable the ONU to report power alarms to the OLT. For more information about the alarm enable command, see EPON Command Reference.
Configuring PoE for all UNIs of an ONU

|
2. Enter ONU or RONU interface view. |
· Enter ONU interface view. · Enter RONU interface view. |
N/A |
|
3. Enable PoE for all UNIs of the ONU. |
onu poe enable |
By default, PoE is enabled for all UNIs of an ONU. |
|
4. Configure a power transmission mode for all UNIs of the ONU. |
onu poe mode { signal | spare } |
By default, the power transmission mode is power over signal cables (signal) for UNIs. |
|
5. (Optional.) Enable nonstandard PD detection for all UNIs of the ONU. |
onu poe legacy enable |
By default, nonstandard PD detection is disabled for UNIs. |
|
6. (Optional.) Configure the maximum PoE power for each UNI of the ONU. |
onu poe max-power { class { class0 | class1 | class2 | class3 | class4 | default } | value max-power-value } |
By default, the maximum power of an UNI depends on the maximum power class of the PD attached to the UNI. |

3. Enable PoE on a single UNI. |
uni uni-number poe enable |
By default, PoE is disabled for a single UNI. The default of the onu poe enable command takes effect preferentially, and PoE is enabled for all UNIs of an ONU. |
|
4. Configure a power transmission mode for an UNI. |
uni uni-number poe mode { signal | spare } |
By default, the power transmission mode is power over signal cables (signal) for an UNI. |
|
5. (Optional.) Enable nonstandard PD detection for an UNI. |
uni uni-number poe legacy enable |
By default, nonstandard PD detection is disabled for an UNI. |
|
6. (Optional.) Configure the maximum power of an UNI. |
uni uni-number poe max-power { class { default | class0 | class1 | class2 | class3 | class4 } | value max-power-value } |
By default, the maximum power of an UNI depends on the maximum power class of the PD attached to the UNI. |
|
7. (Optional.) Configure the power supply priority for an UNI. |
uni uni-number poe priority { critical | high | low } |
By default, the PoE priority of an UNI is critical. |
