Hi
all the switch with version V2R9 is compatable with desired AP
S2700-26TP-PWR-EI
S2700-52P-PWR-EI
S2700-9TP-PWR-EI
S3700-28TP-PWR-EI
S3700-28TP-PWR-SI
S5700-28C-PWR-SI
S5700-28C-PWR-EI
If an 802.3at AP connected to a switch in V200R001, V200R002, or V200R003 is upgraded to V200R008C10, the AP cannot work in 802.3at mode. It can work only in 802.3af mode and its radios may fail to work. To solve this problem, install a patch on the switch if the switch version is V200R001 or V200R003, or upgrade the switch to a later version. If the switch version is V200R002, upgrade it to V200R003 and then install a patch, or upgrade the switch to a later version.
Regards
