poe-power-source
Syntax poe-power-source {internal | external | none}
no poe-power-source
Context config>card>mda
Description This command specifies whether the internal system-level PoE power supply or an external
PoE power supply is used to power the PoE-capable ports on a 7705 SAR chassis.
When the 7705 SAR-H is configured for the internal power supply, standard 15 W PoE can
be enabled only on ports 5 and 6. Port 5 can also support 34 W PoE+, but in that case, port
6 cannot support PoE. When configured for the external PoE power supply, all four PoE-
capable ports support a combination of standard 15 W PoE and 34 W PoE+, with a maximum
power delivery of 83 W among all PoE-enabled ports. Refer to the 7705 SAR-H Chassis
Installation Guide, “Ethernet Ports”, for information about supported combinations and
restrictions.
The following chassis types only support the internal system-level PoE power supply:
• 7705 SAR-Hc
• 7705 SAR-W
• 7705 SAR-Wx
The no form of this command disables the PoE power supply on the node.
Default internal
Parameters internal — specifies that the internal PoE power source be used for the PoE-capable
