1 Product Overview
1.1 Overview
RG-AP840-I(V2) is an 802.11ax-compliant wireless access point product developed for indoor scenarios such
as higher education, government, general education, finance, and business. It uses dual-radio technology, of
which the 2.4 GHz frequency can provide up to 575 Mbps access rate and 5 GHz can provide up to 4.8 Gbps
access rate. The whole machine can provide the maximum wireless access rate of 5.375 Gbps. The ultra-fast
wireless access rate takes performance out of the equation.
The important factors such as wireless network security, RF control, mobile access, service quality assurance,
and seamless roaming are fully considered in the design of RG-AP840-I(V2). It works with a wireless controller
to guarantee data forwarding, security and access control of wireless users.
RG-AP840-I(V2) can be operated in 802.11ax, 802.11ac, and 802.11n modes concurrently. The product supports
ceiling and wall-mounted installation modes, and can be safely and conveniently installed on ceiling and walls.
RG-AP840-I(V2) supports local power feeding or power feeding over Ethernet (PoE). You can flexibly select
appropriate power feeding methods according to the on-site power feeding environment. The product is
especially suitable for large campus, enterprise offices, and operating hotspots.
1.2 Appearance
RG-AP840-I(V2) provides 2 radio frequency ports, 2 Ethernet copper ports (LAN1 supports PoE in compliance
with IEEE 802.3af, 802.3at and 802.3bt, and LAN2/IoT port supports power feeding to IoT units (48 V/0.27 A,
MAX: 12.95 W), 1 5G SFP, 1 RJ45 Console port, 1 external power adapter power socket, 1 USB port, and 1
reset key. The appearance is as follows:
