Introduction

Motorola’s DOCSIS 3.0 Modem includes a number of major

enhancements including channel bonding and IPv6. Motorola’s

DOCSIS 3.0 modems support DOCSIS 1.x, 2.0, and new 3.0

features.

DOCSIS 3.0 provides a number of enhancements earlier versions

of DOCSIS, but most notably, channel bonding. Channel bonding

enables multiple downstream and upstream channels to be

“virtually-bonded” together to be used by a single subscriber. This

increases downstream speeds up to 1 Gbps, and upstream

throughput up to a minimum rate of 120 Mbps. Additionally,

DOCSIS 3.0 supports IPv6and Internet Protocol Television (IPTV).

IPv6 greatly expands the number of Internet addresses that

operators may use.

This document was developed to assist all Technical Operations

employees with the proper steps of installing, configuring, and

troubleshooting the Motorola SB6121 modem.

Installation

The serial number and equipment address can be found on the bottom of the modem. These

items will need to be entered into CSG in order for the gateway to operate.

Additional Warehouse Information

CSG Equipment Type: M1

CSG Equipment Model: SB6121

CSG Equipment Mode: 0

Installation Procedure

Connect one end of the power adapter into the modem and the other end into power outlet or

surge protector.

Connect an active coax cable.

Connect the primary computer to Ethernet port on the modem using a Cat 5 Ethernet cable.

Do not set the modem in an enclosed area, near large appliances, UPS (uninterrupted power

supplies), microwaves, computer monitors or 2.4GHz cordless phones.

Rear Panel Connections

1. An RJ-45 Ethernet port to connect the modem to the computer

2. F-connector connects to an active cable drop

Front Panel Display

The front panel LEDs should be used during installation, configuration, and troubleshooting. Use

them as a visual reference for how and what the modem is performing.

Start-Up Sequence

The SB6121 goes through a series of steps when first connected to power and RF signal.

The SB6121 start-up steps are:

A. Power On Self Test (POST). If LED remains off, modem is faulty.

B. Scanning downstream frequencies.

C. Scanning upstream frequencies.

D. Downstream and upstream acquired. Modem processing for DHCP, TFTP, and TOD.

E. Ready. PC/Activity is solid when a CPE is connected and blinks when transmitting or

receiving data.

F. Powered off.

G. Modem is successfully registered but Network Access Control (NACO) is disabled via

DOCSIS® configuration file.

H. Performing firmware upgrade

DOCSIS 3.0 modems have dual-colored LEDs to visually determine if channel bonding and

Gigabit Ethernet is enabled.

Troubleshooting Tips

Rule out RF

Use the front panel LEDs as well as a SLM to rule out potential signal issues. If the RF levels are

acceptable, most issues can be corrected by restarting the cable modem. To restart the Motorola

SB6121:

1. Shutdown the computer

2. Unplug the cable modem from power and wait approximately 1 minute.

3. Plug the cable modem back into power.

4. Observer the LED light up sequence as detailed above.

5. Restart the computer.

LEDs and Error conditions

Light Turns off during Startup: Turns off during normal

operation:

RECIEVE The downstream (RECEIVE) channel cannot

be acquired. The downstream channel was

lost.

SEND The upstream (SEND) channel cannot be

acquired. The upstream channel was

lost.

ONLINE IP registration was unsuccessful. IP registration was lost.

POWER Verify the power connection. Verify the power connection.

Troubleshooting Tips

Release and Renew the IP address on computer if its unable to access the internet or the

modem’s setup page

Reboot the computer

Disable the proxy settings in the computer’s web browser, and temporarily disable any

firewall software during the setup of the gateway.

Always use straight-through cables, not cross over cables
