*UPoE

The 24 RJ45 ports on the front panel of N3224PX-ON support UPoE. For these UPoE ports, the maximum output power can be set to up to 99 watts. For details about UPoE, please refer to UPoE.
See the link PoE Configuration Commands for PoE command reference.

Note:

The following PoE commands are not supported on N3224PX-ON:

set poe interface max-power

set poe interface mode

set poe interface threshold-mode

set poe power management-mode

25GbE SFP28 Port

Ports Te-1/1/25, Te-1/1/26, Te-1/1/27 and Te-1/1/28 are a group of ports, you should manually configure the port speed for these four ports by using the set interface gigabit-ethernet speed command before inserting an optical module. When configuring the rate, the supported port rates are 25 Gbit/s, 10 Gbit/s, and 1 Gbit/s. The four ports can be configured with the same port rate or different rate. When configured at different port rates, 10G and 1G can coexist, but 25G cannot coexist with other rates. The following table gives several cases of speed setting for this group of ports.

	te-1/1/25	te-1/1/26	te-1/1/27	te-1/1/28	Allowed or not allowed
case #1	10 G	10G	10G	10G	✓
case #2	1G	1G	1G	1G	✓
case #3	25G	25G	25G	25G	✓
case #4	1G	10G	1G	10G	✓
case #5	25G	1G	25G	25G	X
case #6	25G	10G	25G	10G	X
case #7	25G	1G	10G	25G	X

Note:

If the port rate is set to 25 Gbit/s, but a 10 Gbit/s optical module is inserted, the port cannot go up.

HiGig2 stacking ports

N3224PX-ON has one slot for QSFP module at the rear side which can be plugged in 2 x 100G QSFP modules. The port numbers of the QSFP module are x-1/1/1 and xe-1/1/2. They can be used as normal 100G QSFP28 ports.
