Getting to Know the Gateway

This section introduces you to the different components of the Gateway:

Front Surface

The front surface contains no indicators or buttons.

Top Panel and LED Indicators

The top panel contains the single status indicator and the customer logo. Air vents for product ventilation are also present. There are no buttons on the top panel.

LED Indicator Table

• Solid On – Signifies steady state or no action required
• Blinking – Signifies activity in progress or action required

Back panel

Tel port

The Tel RJ-11 ports support up to two traditional phones or DECT base stations to connect to the Gateway. Single-line customers can use the Tel 2/Alarm port to connect an auto dial alarm system.

Ethernet Ports

The RJ-45 Ethernet ports support up to four Ethernet connections (for example, a computer) to your local network.

Three Ethernet ports on the Gateway support Gigabit Ethernet ports and have a maximum speed of 1 Gbps (Gigabit per second).

One Ethernet port (#4) on the Gateway supports 2.5 Gigabit Ethernet ports and has a maximum speed of 2.5 Gbps (Gigabits per second). Ethernet Port 6 supports WAN or LAN access.

Each Ethernet port has two LEDs with the following functionality.

Ethernet ports 1 through 3

Cable port

The Cable port allows you to connect to your local coax network and the broadband network of your services provider. This port also carries the MoCA signaling.

Power inlet

The power inlet (Power) allows you to connect 12V DC Power from the power brick. Only the EPS-6 supplied with the unit may be used with this product.

The USB port uses a USB C connector and contains USB 2.0 signaling and power. The USB port is only intended to communicate with Comcast approved products.

Bottom panel

Product label

The label on the bottom of the Gateway contains key manufacturing information, such as the part number, serial number, CM MAC address, MTA MAC address, and WAN MAC address.

Installation Notes

Local connection requirements

Wireless connection for Wi-Fi

If you want to connect your computer using a wireless connection, your computer must be equipped with a Wi-Fi Certified wireless client adapter.

Wired connection via Ethernet

If you want to connect a computer using a wired connection, your computer must be equipped with an Ethernet Network Interface Card (NIC).

Power to the Gateway

Procedure

Proceed as follows:

1. Use the power brick that is included with your Gateway.
2. Connect the small end of the power cord on the power brick to the Gateway.
3. Plug the power brick into the electrical outlet.
4. Wait at least two minutes to allow the Gateway to complete the startup phase.

Connect your wired devices.

Requirements

• Both your network device (for example, a computer) and Gateway must have a free Ethernet port.
• Your network device must be configured to obtain an IP address automatically. This is the default setting.

Ethernet ports 1 – 3 on the Gateway are Gigabit Ethernet ports and have a maximum speed of 1 Gbps (Gigabit per second). Ethernet port 4 is a 2.5 Gigabit Ethernet port and has a maximum speed of 2.5 Gbps (Gigabits per second).

Procedure

1. It is recommended to use Category 5e or Category 6 Ethernet cables with the Gateway.
2. Plug one end of the Ethernet cable into one of the RJ-45 Ethernet ports on the back of the Gateway.
3. Plug the other end of the Ethernet cable into the Ethernet port of your network device.
4. Your network device is now connected to your network. Use the same procedure to connect other Ethernet devices (computers, network printers, and so on).

Connect your Wi-Fi device.s

Introduction

The Gateway supports three Wi-Fi bands that allow you to connect wireless devices to your network:

• The 6 GHz IEEE 802.11ax access point offers superior transfer rates, is less sensitive to interference, and allows you to connect IEEE 802.11ax wireless clients with 6GHz capability.
• The 5 GHz IEEE 802.11ax access point offers superior transfer rates, is less sensitive to interference, and allows you to connect IEEE 802.11a/n/ac/ax wireless clients.
• The 2.4 GHz IEEE 802.11ax access point allows you to connect IEEE 802.11b/g/n/ax wireless clients. Use this access point for wireless clients that do not support 5 GHz.

If you want to connect your wireless client to the 6GHz or 5 GHz access point, make sure that your wireless client supports these connections.

Requirements

• Your network device must be equipped with a WiFi Certified wireless client.
• Your network device must be configured to obtain an IP address automatically. This is the default setting.

Procedure

If you want to connect a computer using the wireless network, configure the wireless client on your computer with the wireless settings printed on the Gateway’s product label located on the bottom of the Gateway.

How to connect your phone

Introduction

This section describes how to connect the phones for single-line customers.

If you have a two-line setup or a setup involving an alarm, please contact your service provider. This setup must be done by qualified technicians.

Procedure

Connect your traditional phone, external DECT base station, or fax to an active RJ-11 Telephone jack on the back panel of your Gateway.

1. Plug the other end of the telephone cable into the telephone device.
2. Alarm systems must be connected to either port 1 or 2. You are responsible for ensuring that the Alarm system is connected to an active telephone port connected to the phone network.
3. You must verify that each phone line is active by first checking for dial tone and then by placing a call to an active telephone number and checking that both parties can properly hear one another.
