Initial Installation
SCE4255W is designed for Plug-n-Play (PnP) and self-configure which not require any soft-
ware installation to use. When device power on the device, it will start scanning and search for
valid LTE backhaul donor eNB and begin the device Plug PnP and provision processes. The
PnP and provision process will take approximate 6~7 min. to bring up and activate the device
service.
1. Small cell device provides mobile network SON（Self-Organizing Network）, it is plug&
play which can auto configuration to install.
2. Install the Ethernet cable into device WAN port and another cable connector connects to router.
3. Install the Power Adapter DC port into device power jack.
4. When Power & LTE LED steady to flash to green, the device can be used. If the one of LED
keeps still flashing at 30 minutes, please call your agent.
