EN OVERVIEW
The GWN7816(P) is layer 3 managed network switch that allows medium-to-large enterprises to build scalable,
secure, high performance and smart business networks that are fully manageable. It supports advanced VLAN for
exible and sophisticated tra󰀩c segmentation, advanced QoS for prioritization of network tra󰀩c, IGMP/MLD Snoop-
ing for network performance optimization, and comprehensive security capabilities against potential attacks. The
GWN7816P provides smart dynamic PoE output to power IP phones, IP cameras, Wi-Fi access points and other
PoE endpoints. GWN7816(P) can be managed in a number of ways, including the local Web user interface of the
GWN7816(P) switch and CLI, the command-line interface. The switch is also supported by GWN.Cloud and GWN
Manager, Grandstream’s cloud and on-premise network management platform. The GWN7816(P) is the best value
enterprise-grade managed network switch for medium-to-large businesses.

The installation process of the ber module is as follows:
1. Grasp the ber module from the side
and insert it smoothly along the switch
SFP+ port slot until the module is in close
contact with the switch.
2. When connecting, pay attention to conrm
the Rx and Tx ports of SFP+ ber module.
Insert one end of the ber into the Rx and
Tx ports correspondingly, and connect the
other end to another device.
3. After powered on, check the status of the
port indicator. If on, it means that the link is
connected normally; if o󰀨, it means the link
is disconnected, please check the cable
and the peer device whether is enabled.
Notes:
• Please select the optical ber cable according to the module type. The multi-mode module corresponds to the
multi-mode optical ber, and the single-mode module corresponds to the single-mode optical ber.
• Please select the same wavelength optical ber cable for connection.
• Please select an appropriate optical module according to the actual networking situation to meet dierent
transmission distance requirements.
• The laser of the rst-class laser products is harmful to eyes. Do not look directly at the optical ber connector.

• The GWN7816(P) uses a hot-swappable power supply unit to maintain the normal operation of the device.
• The PSU for GWN7816 comes with iron wire to prevent tripping.
• The PSU for GWN7816P comes with power cord anti-trip hole.
• In order to protect the stable power supply, it’s recommended to x the AC cable.
Notes:
For GWN7816:
1. Rotate the iron wire counterclockwise, then insert the AC cable into the power socket.
2. Push the iron wire back until the power cord is secured.
For GWN7816P:
1. Place the smooth side of the xing strap towards the power outlet and insert it into the hole on the side of it.
2. Connect the power cable and PSU1, then slide the protective rope over the xed strap until the end of the power
cord and smoothly wrap the strap around the power cord and lock it tightly.
3. Plug the AC power cord into a power source such as a wall socket or power strip.
4. When you apply power, both the LED on the PSU and the switch’s PSU1 indicator on the front panel that is
associated with the power supply. If these LEDs are not lit, make sure that the power cord is plugged in correctly
and that power source is good.

ACCESS & CONFIGURE
Method 1: Login using the Web UI
1. A PC uses a network cable to correctly connect any RJ45 port of the switch.
2. Set the Ethernet (or local connection) IP address of the PC to 192.168.0.x (“x” is any value between 1-253), and
the subnet mask to 255.255.255.0, so that it is in the same network segment with switch IP address. If DHCP is
used, this step could be skipped.
3. Type the switch’s management IP address http://<gwn7816(P)_IP> in the browser, and enter username and
password to login. (The default administrator username is “admin” and the default random password can be found
at the sticker on the GWN7816(P) switch).
Note: If no DHCP server is available, the GWN7816(P) default IP address is 192.168.0.254.
Method 2: Login using the Console port
Method 3: Login Remotely using SSH/Telnet
1. Use the console cable to connect the console port of switch and the serial port of PC.
2. Open the terminal emulation program of PC (e.g. SecureCRT), enter the default username and password to login.
(The default administrator username is “admin” and the default random password can be found at the sticker on
the GWN7816(P) switch).
1. Turn on the Telnet of the switch.
2. Enter “cmd” in PC/Start.
3. Enter telnet <gwn7816(P)_IP> in the cmd window.
4. Enter the default username and password to login. (The default administrator username is “admin” and the default
random password can be found at the sticker on the GWN7816(P) switch).
Method 4: Congure using GWN.Cloud / GWN Manager
Type https://www.gwn.cloud (https://<gwn_manager_IP> for GWN Manager) in the browser, and enter the
account and password to login the cloud platform. If you don’t have an account, please register rst or ask the
administrator to assign one for you.

Install on a 19” Cabinet (Only for GWN7816P)
Note: GWN7816P can only be installed in cabinets
with a spacing of 380mm-545mm between the front
and rear hole bars.
1. Install the two rear slideways supplied with the acces-
sories on both sides of the switch, and x them with
the provided screws (KM 3*6).
2. Based on the planned installation position of the
switch on the cabinet, conrm and install the two rear
rack-mounting kits at the appropriate positions on the
rear hole strip with screws (prepared by yourself).
3. Install the two front rack-mounting kits on the both
sides of the switch, and x them with the pro-
vided screws (KM 3*6). Please refer to step 2 of
GWN7816’s installation.
4. Hold the switch and install it into the cabinet, embed-
ding the slideways into the rear rack-mounting kits to
ensure they support the switch. After adjusting to the
appropriate position, use screws (prepared by your-
self) to x the front rack-mounting kits to the front hole
strip, ensuring the switch is stable and horizontally
installed on the cabinet.
Note: To avoid high temperatures and keep the device cool, sucient space should be left around the switch for
heat dissipation. The air inlet of the switch cannot face or be close to the air outlet of other devices.
