You should go to the MCC’s Monitor → Card Status → Syslog (A-A-C) and view the event on its system log.
Diagnostics and Troubleshooting Table 7-2. Major Alarms (2 of 2) Failure Type Action Ethernet port failure 1. Check cable connections to the DSLAM. – If cables are terminated properly, go to Step 2. – If cables are not terminated properly, terminate them correctly. 2. Check cable connections to the Hub or Ethernet switch. – If cables are terminated properly, go to Step 3. – If cables are not terminated properly, terminate them correctly. 3. Check the Activity/Status LED at the Ethernet Hub or Switch.
Diagnostics and Troubleshooting Minor Alarms Use Table 7-3 to determine the appropriate action to take for each Minor Alarm. Table 7-3. Minor Alarms (1 of 2) Failure Type Action Config Error 1. Check the Selftest Results display by following the menu sequence: Diagnostics → Selftest. 2. Do another Selftest (Reset) and check results. – If the results are normal, the problem was transient. Log the results. – If Selftest results still show configuration corruption, there is a card problem.
Diagnostics and Troubleshooting Table 7-3. Minor Alarms (2 of 2) Failure Type Action Link Down Threshold (A trap message is sent if the number of DSL link down events in 15 minutes exceeds the selected value.) H If the threshold is set low (1–4), and the link is currently down, then there may be a loop or SN problem. Check both. – Verify that the SN is powered up, is connected to the loop, and has passed its Selftest.
Diagnostics and Troubleshooting Network Problems Review the following symptoms and possible solutions to help in solving any problems you may encounter on the Hotwire DSLAM. PROBLEM: Intranetworking communication problems. ACTION: 1. Verify that the internetworking network cables meet IEEE standards for local Ethernet networks. 2. Check cable connections to DSLAM and other devices in the network. 3. Determine whether or not your system is the only one in the network with a problem.
Diagnostics and Troubleshooting No Response at Startup PROBLEM: DSL cards do not respond at startup after rebooting chassis. ACTION: 1. Reset the MCC card. 2. Be sure LEDs go through the reset sequence once. Then, a second time after 15–20 seconds. Cannot Upload Configurations to a Unix Server PROBLEM: TFTP server denies write permission (Message is “TFTP recv failure”). ACTION: 1. Before uploading configurations, create a dummy file and give it global Read-Write permissions. 2.

Download Code and Apply Download A The Download Code menu option on the Hotwire DSLAM gives you the ability to upgrade your software with a new version of code and then apply this code to your system. New firmware releases are typically applied to either the MCC or DSL cards in your system. When a software upgrade affects both the MCC and the DSL cards, you must download and apply a new version of code into each of the DSL cards before you download and apply a new version of code into the MCC.
Download Code and Apply Download TFTP Server Configuration When you are downloading code to an endpoint, configure your TFTP server with the following timeout values: H Retransmission timeout – Value not less than 10 seconds. H Total transmission – Value not less than three times the retransmission timeout. You may also use the above values for a standard TFTP transfer. NOTE: Before initiating a download, verify that you can Ping to the TFTP server. If you can not, do not proceed with the download.
Download Code and Apply Download Download Only System: Automatic Immediate Apply In order for the system to become fully functional again, you must start the Download Code file transfer procedure. Enter the image file name and the TFTP Service IP address. Select yes to begin the file transfer. When the file transfer has successfully completed, the system will automatically restart and become fully functional with the newly acquired firmware.

Traps B Traps are configured via a Telnet or terminal session. The addition or removal of a card or another hardware component within the Hotwire DSLAM system causes a trap to be generated. These traps indicate a configuration change notification (CCN) of a card (a hardware replacement or a software upgrade). DSL Card Traps The DSL card sends the following traps. Event Trap Class Comment Trap # – MIB * Device failure major AN’s operating software has detected an internal device failure.
Traps Event Trap Class Comment Trap # – MIB * CCN (Configuration Change Notice) warning Configuration change caused by one the following events: 1–ent H change affecting the entity MIB xDSL link up or down minor Number of link down events above threshold. This rate is limited to once every 15 minutes. 1–dsl xDSL port speed low warning Port speeds decreased to lower bound thresholds. 2–dsl xDSL port speed normal normal Port speed now above lower bound threshold.
Traps Event Trap Class Comment Trap # – MIB * xDSL test start normal Test started by any means. 6–dsl xDSL test clear normal Test over. 106–dsl DHCP filter security failure minor Can not add new route to route table because maximum number of stored rules reached. 11–dhcp SN device mismatch minor SN identified on port N does not match device described in port configuration role.
