Operation Manual - PoE
Quidway S6500 Series Ethernet Switches
Note:
When setting the maximum PoE power supplied by the switch with the poe power
max-value command, you must set it to a value greater than the total power that has
been distributed to the boards. Otherwise, this command cannot be executed
successfully. This maximum power can be 37 W to 2400 W.
You can successfully enable PoE on a board only when the remaining power of the
switch is not less than the full power of this board.
The required power of PDs may exceed the power configured for them due to their
unstable status, thus causing the PDs connected to the last port on the board to be
powered off. Therefore, when you configure the maximum power value for a board,
ensure enough power for all ports of the board and reserve additional 20 W power
for instant high power at the same time.
Once PoE is enabled on a board, the system reserves the power for the slot even
after you remove the board from the slot; in this case, you can use the undo poe
enable slot command to release this power.
The reserved power for a blank slot will be recycled automatically by the system if
you insert a PoE-incapability board into the slot.
The reserved power for a blank slot will still be distributed to the slot if you insert a
different type of board into the slot and the board is PoE-capable.
Before you enable the PoE-compatibility detection on a board, you must first enable
PoE on this board with the poe enable slot slot-num command.
PoE-compatibility detection against non-standard PD is slow and has impact on the
system performance, so you are recommended not to enable the PoE-compatibility
detection on a board to check if the connected PDs are IEEE802.3af-compatible.
Currently, the S6506 switch does not support the spare mode. If a PD only supports
the spare mode, a conversion will be needed.
When a board is almost fully loaded and a new PD is added, the switch will respond
to the PD according to the PoE management mode. For details, see 1.1.4 Setting
PoE Management Mode.
The PoE priority of each port is based on its board. In other words, the switch cannot
compare the priorities of ports on different boards.

1.3 Configuration Example

I. Network requirements
Two PoE-capable boards are installed in slot 3 and 5 on an S6500 series switch.
Ethernet3/0/1 to Ethernet3/0/48 are connected with IP phones and Ethernet5/0/1
to Ethernet5/0/48 are connected with access point (AP) devices.
