Thank you for purchasing a Huawei AR series router. This guide describes how to install AR502 and AR509CG series
routers. It also explains how to log in to your router for the first time.
For more information, see the Hardware Installation and Maintenance Guide for your router on the Huawei
support website.
The installation, connection, and login methods of AR502 series routers and AR509CG are similar. This
document uses the AR502G-L-D-H and AR502EGRz-L routers as an example.
Figures in this document are for reference only and may not show the actual appearance of the router.

Do not place this product in an environment with flammable or explosive gases, or smoke.
The installation site must be free from leaking or dripping water or heavy dew. If the relative humidity is high,
use dehumidifiers or air conditioners with dehumidification features.
The installation site must be well ventilated, and the air vents of the router must not be blocked.
Do not place the router in a dusty environment.
Leave more than 100 mm clearance at two sides and rear of the router for heat dissipation.
100mm
Use a Phillips screwdriver to loosen the screw on the SIM card cover, and remove the SIM card
cover from the router. Keep the SIM card cover in an appropriate place for later use.
Push the SIM card holder toward the OPEN direction and turn it upward. Place the SIM card into
the SIM card slot, close the SIM card holder, and push the SIM card holder toward the LOCK
direction. When you hear a click, the SIM card holder is locked.

When inserting a SIM card, keep the notch on the SIM card in the same direction as the notch marked on the slot.
CAUTION
NOTE A SIM card is not hot swappable.
Industrial SIM cards are recommended for the router.
If only one SIM card needs to be installed, install it in slot SIM1.
For an AR502CG-L router, remove the SIM card cover on the front panel, and then insert a SIM card.
During installation and maintenance, take ESD protection measures, for example, wear ESD gloves or an ESD
wrist strap.
During router transport, movement, and installation, prevent the router from colliding with objects like doors,
walls, or shelves.
This product is used in restricted scenarios and must be operated by trained personnel.
Do not place other objects on the router.
CAUTION
To ensure personal and equipment safety, observe all the safety precautions on the equipment and in this
document. and items do not cover all the safety precautions and are only supplementary to
the safety precautions.
Follow all the safety precautions and instructions provided by Huawei. The safety precautions outlined in this
document are only those that Huawei can predict. Huawei is not liable for any consequence that results from
violation of regulations pertaining to safe operations or safety codes pertaining to design, production, and
equipment use.
WARNING CAUTION
WARNING AR routers are class A products. In a domestic environment, these products may cause radio interference
in which case the user may be required to take the adequate measures.

NOTE For an AR502CG-L, skip this step because it does not need rubber pads.
Scenario 1: Installing the Router on a Desk
Ensure that the desk is flat and properly grounded.
Leave at least 50 mm of clearance around the router for heat dissipation.
Do not place other objects on the router.
CAUTION
Attach four rubber pads in the imprinted round areas marked plus (+) signs at the bottom of the router.

Use the Phillips screwdriver to install two M4x8 pan
head screws in the marked positions on the wall,
and leave 2 mm of the screws out of the wall.
Hang the router on the M4x8 pan head screws
through mounting holes on the mounting bracket.
Fasten the M4x8 pan head screws with the Phillips
screwdriver.

Use a measuring tape to determine the two mounting bracket installation positions. Keep the two
positions on a horizontal line and mark the positions with a marker.

Scenario 2: Mounting the Router on a Wall
Before drilling holes on a wall, make sure there are no power cables in the wall to avoid electric shock.
Take water-proofing measures to protect a wall-mounted router from damages caused by water.
Screws must be installed solid in the wall; otherwise, the wall-mounted router may fall down after cables are
connected.
Ensure that there are no flammable or explosive materials near the router and no obstructions within 100 mm
around the router.
CAUTION

Horizontal mounting
NOTE Before install the mounting bracket on an AR502CG-L
router, remove the DIN mounting kit at the back of the
router.
NOTE The center distance between the two mounting holes
for the mounting bracket is 74 mm.

NOTE If the spring latch is too tight to move down, you can pull down the spring latch during the installation.
NOTE The DIN mounting kit is optional and needs to be purchased separately if needed.
For an AR502CG-L router, skip step 1 because the DIN mounting kit has been installed on the router before
delivery.
Scenario 3: Mounting the Router on a DIN Rail
Mount the DIN mounting kit onto the rear panel of the router with M3 screws, and then use a Phillips
screwdriver to tighten the M3 screws.
Place the rear panel of the router in front of the DIN rail and ensure that the DIN rail fits in between the
fixture near the top of the DIN mounting kit and the spring latch near the bottom.
Make the router incline forward with the bottom away from the DIN rail, and place the fixture at the rear of
the DIN mounting kit on the top of the DIN rail.
Slowly push the router toward the DIN rail to make the spring latch near the bottom of the DIN mounting
kit move down. The spring latch then bounces back to fix the router on the DIN rail.

WARNING
5.3 (Optional) Installing the AR502EGRz-L or AR502EGRz-Lc Router in an IP65 Enclosure
Assembly Box/Installing the AR502EG-L-PD
To avoid electric shock, do not connect power cables while the power is on.
When putting the cover back to the IP65 enclosure assembly box, ensure that the O-ring is flat and there is no
large gap after screws are installed. In addition, take water-proofing measures to ensure the sealing performance,
protecting the router from damages caused by water.
Screws must be installed solid in the wall; otherwise, the router may fall down after cables are connected.
Ensure that there are no flammable or explosive materials near the router and no obstructions within 100 mm
around the router.
To insert a USB flash drive in or remove it from a USB interface on the box bottom, ensure that the power is off.
Do not touch the USB flash drive when it is in use.
This product is applicable to level II overvoltage scenarios. If you want to apply it to a scenario where overvoltage
is higher than level Ⅱ, connect an effective voltage drop device to the circuit breaker. Otherwise, you may face
risks of electric shocks.

Pull the power cable out from the PG interface of the IP65 enclosure assembly box.

Scenario 1: Installing a Router in an IP65 Enclosure Assembly Box (Wall-mounted)
Install the mounting bracket on the IP65 enclosure assembly box.
a. Put the mounting bracket on the back of the IP65 enclosure assembly box. Adjust the position of the
mounting bracket to align the mounting holes on it with the four screw holes on the router.
b. Use the four M5x10 screws to secure the mounting bracket to the IP65 enclosure assembly box.
2
Attach the IP65 enclosure assembly box mounting bracket to the wall and keep its top and bottom edges
horizontal. Use a marker to mark four mounting positions, two at the top and two at the bottom.
