XP-DSM Network Conﬁ guration Quick Start Guide

Power

The following instructions cover basic network conﬁ guration for operation of the XP-DSM using a single IP address. Additional information is available in the XP-DSM Technical Manual available at www.alpha.com.

To prepare your network to read incoming data from ﬁ eld installed XP-DSMs, complete the following steps:

Step 1: Prepare a DOCSIS Conﬁ guration File

Prepare a type-length-value conﬁ guration ﬁ le for the cable modem. The ﬁ le should include the modem’s community strings settings. If a DSM Setup File is going to be used to distribute transponder settings (see step 5), then the parameter docsDevSwServer must be set in the DOCSIS Conﬁ guration File with the IP address of the TFTP server on which the DSM Setup File is saved. This entry may be deﬁ ned as either type 21 or type 11.

NOTE:

Sets Read-Write Community string. Set the IP addresses and community strings to ﬁ t your system.

Sets Read-Only Community string. Set the IP addresses and community strings to ﬁ t your system.

Speciﬁ es location of DSM Setup File atidoc01.cfg

Example File

SNMP MIB Object (11) [Len=21]:docsDevNmAccessStatus.1/4 SNMP MIB Object (11) [Len=21]:docsDevNmAccesslp.1/10.56.21.0 SNMP MIB Object (11) [Len=21]:docsDevNmAccesslpMask.1/255.255.255.0 SNMP MIB Object (11) [Len=25]:docsDevNmAccessCommunity.1/"RW STRING" SNMP MIB Object (11) [Len=21]:docsDevNmAccessControl.1/3

SNMP MIB Object (11) [Len=21]:docsDevNmAccessStatus.2/4 SNMP MIB Object (11) [Len=21]:docsDevNmAccesslp.2/10.56.21.0 SNMP MIB Object (11) [Len=21]:docsDevNmAccesslpMask.2/255.255.255.0 SNMP MIB Object (11) [Len=25]:docsDevNmAccessCommunity.2/"RO STRING" SNMP MIB Object (11) [Len=21]:docsDevNmAccessControl.2/2

SNMP MIB Object (11) [Len=21]:docsDevSwServer.0/10.20.30.40

The XP-DSM will inherit the cable modem community string settings provided by the DOCSIS conﬁ guration ﬁ le. If the cable modem is left unsecured, the XP-DSM uses the default community strings AlphaSet and AlphaGet.

Step 2: Provision the DHCP Server with the XP-DSM's RF MAC Address

On the DHCP Server, assign the RF MAC Address the DOCSIS Conﬁ guration File created in Step 1. The RF MAC Address is located on front of the XP-DSM. The XP-DSM accepts either a static or dynamic IP address assignment.

Step 3: Install the XP-DSM Hardware

Refer to the XP-DSM Hardware Installation Quick Start or the XP-DSM Technical Manual, both available at www.alpha.com.

Step 4: Compile the MIB ﬁ les on the SNMP Management Server

Download the Alpha MIB (ATI-TABLES-MGMT-MIB) from www.alpha.com; type XP-DSM in the search box to bring up the ﬁ le. The Alpha MIB is used to set DSM speciﬁ c settings. The SCTE-HMS MIB ﬁ les are required for the SNMP management server to collect data from the transponders. The ﬁ les are available on the Society of Cable Telecommunications (SCTE) Web site (www.scte.org). They must be compiled in the following order: SCTE-ROOT, SCTE-

HMS-ROOTS, SCTE-HMS-PROPERTY-MIB, SCTE-HMS-ALARMS-MIB, SCTE-HMS-PS-MIB, SCTE-HMS-GEN-MIB.

Step 5: Set Communication Options

There are three ways to set the XP-DSM communication options: using SNMP in a MIB Browser, using the Local port, and using a DSM Setup File. Before proceeding, verify UDP ports 161, 162, and TCP port 80 are not blocked.

Setting Options Locally

The local port allows a technician to monitor and set XP-DSM parameter values directly using a personal computer and a Local Port Adapter Cable (Alpha P/N 745-826-21). Terminal emulation software is necessary (HyperTerminal is recommended). Serial communication settings are:

Baud: 19200 Data Bits: 8 Parity: None Stop Bits: 1 Flow Control: None

To change settings:

1. Launch the terminal emulation software

and hit ENTER to display the menu of CIB tables.

2. Enter >[ﬁ rst three letters of table] and ENTER to display the contents of a table.

To disable the HTTP Server, which appears in the DISCRETE Table as:

SYS-1 10 HTTP SERVER 1 ENABLED YES

3. To set a parameter value, enter: >[table] [subsystem] [Index] [Value], and hit ENTER.

Enter: >dis sys 1 10 0 and hit ENTER. The result will be:

NOTE: Entries in the TEXT Table do not have

subsystems. Example: To set a SNMP Trap Target to 10.20.30.40 Enter Command:

>tex 20 10.20.30.40 and hit ENTER.

SYS-1 10 HTTP SERVER 0 DISABLED YES

Setting Options with a DSM Setup File

An optional DSM Setup File, atidoc01.cfg, distributes settings automatically to XP-DSMs on a network. The XP-DSM is programed to look for atidoc01.cfg at initialization and after every twenty-four hours of operation. If the ﬁ le is not present the XP-DSM will retain its settings. To build a DSM Setup File, enter SNMP parameters from the Alpha MIB and their desired values inside a TLV ﬁ le using a TLV editor. The entry atiMgmtSysDownloadCfgCheckProgress with the value of 3 is the ﬁ le marker that the XP-DSM looks for to begin reading entries and must be the ﬁ rst entry in the ﬁ le. Name the ﬁ le atidoc01.cfg and place it in the Root Directory of the TFTP Server speciﬁ ed by the docsDevSwServer parameter in the DOCSIS Conﬁ guration File. See the XP-DSM Technical Manual for complete instructions on building a DSM Setup File and for Alpha MIB parameter deﬁ nitions.

Example Command

Step 6: Test the Connection

There are two methods to test whether a connection has been established: Method One: Type the IP address of the transponder into a Web browser.

Click a link to see the associated power supply data.

Example of the Analogs power supply window

Method Two: To check connectivity and verify power supply data, the XP-DSM can be accessed with SNMP. Check data within the psIdent MIB branch of the SCTE-HMS Tree by performing anzzz SNMP MIB walk to the SCTE-HMS-MIB branch 1.3.6.1.4.1.5591.1. Verify that power supply data measurements are present.

NOTE:

See the XP-DSM Technical Manual available at www.alpha.com for extensive network conﬁ guration and option setting instructions, including MIB parameter deﬁ nitions.
