Local Port: At the command prompt type TEXT. The rmware version will be displayed next to the
SysDescr variable and will disaply as ‘ATI P01V1.10.0’ indicating rmware version 1.10.0.
SNMP: SCTE-HMS CommonVendorInfo: OID: 1.3.6.1.4.1.5591.1.3.1.5. See Section 5.0.
What is the purpose of the DOCSIS CongurationFile?
A DOCSIS Conguration File is required for all DOCSIS cable modems and provides settings for the
cable modem. Settings in the DOCSIS le for the XP-DSM are optional and include setting SNMP
security (community strings) for the modem and for upgrading the rmware for the modem.
In Single IP Mode, if the community strings are not set in the DOCSIS Conguration File, only the
power supply SNMP MIB varbinds (enterprise.5591 and enterprise.926) will require community
strings AlphaGet (Read) and AlphaSet (Read/Write) default. However if the cable modem community
strings are set in the DOCSIS Conguration File they will override the DSM defaults. See Section 3.2.
Is there a way to set options on multiple XP-DSMs without visiting each site?
The DSM Setup File allows automated distribution of communications, power supply, and rmware
upgrade options to every XP-DSM on the network. See Section 3.4.
Can the XP-DSM be set to generate SNMP traps?
The XP-DSM supports the SNMP alarms dened in the SCTE-HMS Property MIB. See Section 6.3.
What if traps are not being received by the SNMP manager?
• Disable personal rewalls on computer receiving traps.
• Disable rewall clients in network interface properties, e.g. Check Point SecuRemote.
• Ensure DSM trap table is populated – atiMgmtSnmpTrapTable OID: 1.3.6.1.4.1.926.1.3.1.1.
• Ensure SCTE-HMS propertyTable and discretePropertyTables are congured to sent traps on
desired power supply conditions.
• Ensure port 162 is not blocked or ltered.
How is the cause of a psMajor Alarm determined?
With most transponders a site visit is required to look at the LCD on the XM2. With the XP-DSM,
however, the cause of a psMajor alarm can be determined by looking at the ‘DISCRETES’ table either
through the XP-DSM Web page or through SNMP MIB atiCibDiscTable. The XM2 parameter that
caused the alarm will have a value of ‘ALARM’. See Section 6.3.
HowisrmwareupgradedontheXP-DSM?
The XP-DSM uses TFTP to upgrade the power supply monitoring (HMS) rmware and is independent
of the modem rmware. The DSM Setup File can be used to automate the upgrade, or an Alpha-
provided software application can be installed and managed from any Windows or Sun Solaris server
on the XP-DSM’s network. See Section 5.2.
