Connecting the Power-over-Ethernet Module (Optional)
Connecting the Power-over-Ethernet Module (Optional)
If you purchased a power-over-Ethernet (PoE) module to provide inline power to devices, connect the
four Ethernet cables on the PoE module to the four LAN Ethernet ports on the router. Make sure you
connect all four Ethernet cables. If the cables are too close together for easy insertion, move the plastic
cable guard away from the connector end of the cable. See
Figure 4-5
.
Caution
Do not connect the PoE module power supply to the PoE module before you connect the PoE module to
the router. For information about connecting the power supply to the PoE module, see the
“Connecting
the AC Adapter”
section.
Figure 4-5
Connecting the Power-over-Ethernet Module to the Router
After you connect the PoE module to the router, connect the Ethernet devices to the ports on the PoE
module, rather than to the Ethernet ports on the router.
Note
When you connect a device (such as a PC or IP phone) to the PoE module, you may notice a 1- to
2-second delay before the LED indicator for the port comes on.
