1 Product Introduction
1.1 Overview
RG-SAP885-SP is a Wi-Fi 6E wireless access point (AP) released by Ruijie Networks for
indoor scenarios in the higher education, government, general education, finance, and
business sectors. It supports three radios, among which the 2.4 GHz band can provide a
maximum data rate of 574 Mbps, the 5 GHz band can provide a maximum data rate of
up to 2.402 Gbps, and the 6 GHz band can provide a maximum data rate of up to 4.804
Gbps. The AP can provide a combined date rate of up to 7.780 Gbps, which eliminates the
bottleneck in wireless performance.
The design of RG-SAP885-SP considers factors including wireless network security, radio
control, mobile access, QoS, seamless roaming, and IoT module expansion. The RG-
SAP885-SP can be used together with Ruijie's access controllers (ACs) to implement STA
data forwarding, security, and access control.
The RG-SAP885-SP can work in IEEE 802.11ax, 802.11ac, and 802.11n modes
simultaneously. It can be mounted against a wall, a ceiling, and other location. Moreover,
the RG-SAP885-SP supports local power supply and power over Ethernet (PoE), which can
be selected based on power supply conditions. It is very suitable for large campuses,
enterprise offices, hotspots, and other high-density scenarios.
1.2 Product Appearance
The RG-SAP885-SP provides three RF ports, two Ethernet copper ports, one 5G SFP port,
one RJ45 console port, one power port for external power supply device, one USB port,
and one reset button. For the two Ethernet copper ports, LAN 1 port supports IEEE
802.3af/at/bt-compliant PoE and LAN 2/IoT port can be used to supply power to the IoT
module (48 V/0.27 A, maximum power of 12.95 W).

The AP adopts the fan-free design. Therefore, maintain sufficient clearance around
the AP for air circulation.
The AP is advised to work in IEEE 802.3at power supply mode to achieve the best
performance.
If IEEE 802.3af power supply is adopted, the AP can be normally powered on, but
only one stream is available for 2.4 GHz and 5 GHz, and the LAN2 port and USB port
cannot supply power to external devices.
If IEEE 802.3at power supply is adopted, the AP can be normally powered on, but the
LAN2 port and USB port cannot supply power to external devices.

1.6 Optical Module
The peer device connected to the 2.5 Gbps optical port of the AP should provide an optical
or copper port. However, the two devices may use different optical modules and support
different port rates, so the final negotiated access rate is not fixed. For details, see Table
1-11 and Table 1-12.
