17 totalHow do I reboot (power cycle) the modem without resetting it to factory defaults?
Press and hold the Reset button for 4 to 10 seconds to reboot (power cycle) the modem without clearing its settings. Holding the button for 10 seconds or more will trigger a full factory default reset, so be careful not to hold it too long. (Page 5)
What do the Battery LED colors and behaviors mean?
A solid blue Battery LED means the battery is at 21% usable charge or higher, while a solid red LED means it is at 20% or lower. A flashing red LED indicates the battery is at 10% or lower, and the LED will ease between blue and off while the battery is charging. If no battery is installed, the LED will be off. (Page 6)
How do I install and connect the modem?
Connect the coaxial cable to the cable connector on the rear panel and to the cable wall outlet, then connect the supplied Ethernet cable from the Internet port to a wireless router or Ethernet-enabled device. Connect an RJ-11 phone cable to the Voice 1 port (and up to Voice 4) if voice service is provisioned by your service provider, then plug the power adapter into the Power port and into a wall outlet. Do not bend or over-tighten the coaxial cable, as this may damage the connector. (Page 3)
What does the Voice LED behavior indicate?
A solid blue Voice LED indicates voice service is active and a phone cable is connected to the voice port. If the phone is off-hook, the LED eases between blue and off, and if the modem is powered by the internal battery while off-hook, it flashes between blue and off. If voice service is not provisioned or a phone connection cannot be established, the LED will be off. (Page 6)
What are the maximum data speeds supported by this modem?
For downstream, the modem supports up to 5Gbps via two 192MHz DOCSIS 3.1 OFDM channels, or up to 1372Mbps via 32 DOCSIS 3.0 downstream channels. For upstream, it supports up to 2Gbps via two 96MHz DOCSIS 3.1 OFDMA channels, or up to 246Mbps via 8 DOCSIS 3.0 upstream channels. Actual speeds may vary based on network configuration and connected devices. (Pages 7–8)
What are the operating temperature and humidity requirements for the modem?
The modem is designed to operate in temperatures between 0°C and 40°C (32°F to 104°F). Humidity should be kept between 5% and 95%, non-condensing. (Page 8)
