 Note:
z The refresh update mode is to upgrade the valid software in the PSE through
refreshing the software, while the full update mode is to delete the invalid software
in PSE completely and then reload the software.
z Generally, the refresh update mode is used to upgrade the PSE processing
software.
z When the PSE processing software is damaged (that is, no PoE commands can be
successfully executed), you can use the full update mode to upgrade and restore
the software.
z When the upgrading procedure in refresh update mode is interrupted for some
unexpected reason (such as power-off) or some errors occur, if the upgrade in full
mode fails after restart, you must upgrade in full mode after power-off and restart of
the device. In this way, the upgrade procedure succeeds.

1.4 PoE Configuration Example
I. Networking requirements
z Two PoE-enabled boards are installed in slot 3 and 5 on an S7506 switch.
z Upgrade the PSE processing software of the PoE board in slot 5 of the S7506
switch online.
z Ethernet 3/0/1 to Ethernet 3/0/48 are connected with IP phones and Ethernet 5/0/1
to Ethernet 5/0/48 are connected with access point (AP) devices.
z PoE does not need to be enabled on the IP phones connected to Ethernet 3/0/1
and Ethernet 3/0/48.
z Ethernet 3/0/48 requires high priority.
