  3. Stick the face plate on the indicated area. Please refer to the illustration on the right.


To set up the phone, follow the steps below:

  1. Plug in the phone cord to the handset RJ9 port and then connect it to the base.
  2. Connect the LAN port of the phone to the RJ45 socket of a hub/switch or a router (LAN side of the router) using the Ethernet cable. This step can be skipped if using GHP620W & GHP621W with Wi-Fi.
  3. Power up the phone:
    • For GHP620W & GHP621W: Connect the 12V DC output plug to the power jack on the phone; plug the power adapter into an electrical outlet.
    • For GHP620 & GHP621: A PoE switch must be used in step 2.

The GHP620W/GHP621W is preconfigured to connect to a default SSID named “wp_master” with password (WPA/WPA2 PSK) “wp!987@dmin”. Users can also modify these settings from the phone’s web UI.
