Cisco GainMaker Reverse Segmentable Node - 1GHz Installation Instructions

GainMaker Node
HMS Status Monitor Transponder
Installation Instructions
Overview
Introduction
The GainMaker® Node Hybrid Management Sublayer (HMS) Transponder (part
number 4006432) is designed to be installed in the lid of the GainMaker Node
housing. The HMS Transponder complies with the Society of Cable
Telecommunications Engineers (SCTE) HMS standard, which allows an element
management system (EMS) to monitor the components in a cable network.
The transponder can be configured after it is installed in a powered node, either
on a test bench or on site. The transponder must be configured before it can be
activated in the EMS.
Purpose
These installation instructions will enable cable system operators or installers to
properly install and configure a GainMaker Node HMS Transponder in a
GainMaker Node.

Installing the Transponder
Installing the Transponder
The transponder module mounts in the lid of the GainMaker node housing. The
transponder mounting location is shown below.
Note: You must mount the transponder module in a GainMaker Node housing
before you can configure the transponder module.
To Mount the Transponder in the Node Housing
Complete the following steps to mount the transponder in the node housing.

Installing the Transponder
1
Record the MAC address and physical location of the node for reference by
network management software. Write the physical location on the gray label on
the transponder module (see figure).

Open the GainMaker node housing. Note the position and orientation of the
transponder in the lid of the housing.
WARNING:
Protect yourself from electric shock and your system from damage. Take
precautions when working with this equipment. Certain components can
deliver electrical shock or cause burns.
3
Position the transponder module with the bar-code label facing you. Align the
connectors on the other side of the transponder module with the mating
connectors on the interface board. Use the two tabs on the other side of the
transponder as a guide to position the transponder module correctly.
4
Push down on the module of the transponder module until it clicks into place.
5
Tighten the two module retaining screws on the transponder to 6.2 in-lb (0.7
Nm).
Transponder Signaling
Three front-panel status LEDs indicate the transponder operating condition.

Installing the Transponder
LED
Indication
Heart Beat
This green LED flashes approximately once per second if the
transponder receives the correct voltage.
Receive
This green LED flashes if data packages are detected (e.g., to
another transponder). If the data packages are addressed to this
transponder, the LED flashes for 3 seconds.
Error
This red LED flashes during start-up. If this LED illuminates
during operation, a system failure has occurred.
Start/Restart Signaling
Immediately after the transponder starts or restarts, all LEDs illuminate and remain
on. Approximately 7 seconds later, the Receive and Error LEDs turn off and the
Heart Beat LED begins flashing rapidly until the transponder locates an open
communication frequency. When the transponder finds an open frequency, the
Heart Beat LED slows to approximately one flash per second.

Configuring and Enabling the Transponder
Configuring and Enabling the Transponder
You must configure the transponder before activating it in the EMS. You can
configure the transponder after installing it in a powered node, either on a test bench
or on site.
You can configure the transponder in one of two ways:
 Locally, using the Handheld Programming Terminal, Model 1200 (part number
A91200.10)
 Remotely, by letting the transponder and the EMS perform automatic
configuration
Note: Remote configuration requires the transponder and EMS to find available
transmit and receive frequencies. When using this method, be sure to allow for a
delay of up to 14 hours in communication.
To Configure the Transponder Locally
Complete the following steps to configure the transponder using the Handheld
Programming Terminal.
1
Insert the 3-mm plug of the Handheld Programming Terminal into the Local
Control Port on the transponder.
Note: Be sure that the plug is fully inserted into the port.
2
Confirm that the handheld is powered up and that the transponder is
responsive. If the GainMaker node is active, the green Heart Beat LED will blink
to indicate that the transponder is operating.
3
Set the configuration parameters as needed for your installation. See
Configuration Parameters below for descriptions.
4
Disconnect the handheld, close the housing, and tighten the closure bolts to the
proper specifications. Refer to the housing installation instructions for torque
specifications.
To Configure the Transponder Remotely
Complete the following steps to configure the transponder remotely.
6
1
Allow up to 14 hours for the transponder and EMS to find available transmit and
receive frequencies.
2
Enable the transponder via the EMS and confirm that the transponder is
responsive. The green Receive LED on the transponder will flash for 3 seconds to
acknowledge packets received from the EMS.
3
Set the configuration parameters as needed for your installation. See
Configuration Parameters below for descriptions.

Menu/Parameter
Description
Receive Frequency
(45-174 MHz)
Sets the frequency that the transponder receives data from the
HFC modem at the headend. The factory setting is 109 MHz, but
can be changed from 45-174 MHz in 50 kHz steps.
Transmit Level (84110 dBµV)
Sets the carrier level transmitted by the transponder. The factory
setting is 100 dBµV (40 dBmV), but can be changed from 84-110
dBµV (24-50 dBmV) in 2 dB steps.
