2 Troubleshooting 2.1

Troubleshooting by front panel LEDs The malfunctions are pointed out through LEDs on the equipment and on the indoor assembly front panel (see Figure 2). The function of the front panel indications is described in section 2.2 Troubleshooting by LCT. All models of the “FlexiHybrid” support a variety of front panel configurations that depend on the capacity configuration. Figure 2 shows a typical “FlexiHybrid” 1+0 and 1+1 configuration and the associated LEDs displayed on the front panel. The controller, standard I/O, and each modem card have a status LED.

Table 4

Modem status LED

The controller status LED is the primary front panel indicator of alarms. An alarm is generated when a specific condition is identified and is cleared when the specified condition is no longer detected. When an alarm is posted: 1. The controller status LED turns orange for 5 seconds 2. The controller status LED turns off for 5 seconds 3. The controller status LED flashes orange for the number of times specified by the first digit of the alarm code 4. The controller status LED turns off for 3 seconds 5. The controller status LED flashes orange for the number of times specified by the second digit of the alarm code Steps 2-5 are repeated for each alarm posted. The entire process is repeated as long as the alarms are still posted. The standard I/O and modem status LEDs set to red when certain alarms are posted. A complete list of alarms is given in Table 5.

Troubleshooting

2.2

Troubleshooting by LCT The equipment is provided with an alarm system, with different signaling modes (via software, LED, connector outputs), that starting from an alarm signal allows the operator to promptly identify the failed module or function. Each time an alarm is posted or cleared, a log of such posting or clearing is localized on the IDU (300 message deep circular buffer) and sent to a syslog server, if so configured. The alarm severity mapping is based on Syslog severity as in Table 5. Alarm severity

Table 5

Alarms mapped

Each alarm can be masked by the user via GUI or SNMP. Each posted alarm generates an SNMP trap (if SNMP traps are configured), as well as when cleared. Each alarm can be mapped to the output alarms 1-4 as per user configuration. The alarm codes shown in Table 6 start flashing orange to indicate the alarm status on the Controller Card LED. The Alarm codes for the controller card faults flash red. When an alarm is posted the LED to RED column in Table 6 specifies which, if any LED is set to the red color. Alarm

The framer is always receiving from both east and west modems in a 1+1 configuration and may switch active receivers if the quality is better on one side versus the other. The receive protection switch is an informational alarm to note a switch occurred. Both east and west receivers are always receiving the data. The system chooses the cleanest receive channel. The 0x1 code indicates that there was one receive protection switch, since the system software read the count in the Master IO FPGA. The count is the number of receive protection switches since the last read. Receive protection switching would be expected in fade testing, since the quality of the signal is being diminished and the Framer is having to try to choose the best signal.

Make front panel connections to the unit and, if necessary, power ON the “FlexiHybrid”. 5. Verify proper unit operation. 5.1 If the Controller unit has been changed, reprogram the IP addresses.

☞ Note on the hot insertion of the Modem unit There is no problem, when a unit is fully inserted in one shot, but if the unit is plugged just to light up some LEDs, then the "modem_fault" alarm switches on (complete with a steady red LED on the unit itself); fully inserting the unit at this stage (i.e. pushing it all the way) keeps the alarm forever, even if all seems to be working all right. In a case like this, it is required to extract and plug the Modem unit again.

☞ Note on the extraction/insertion of the modem unit It is possible to extract and insert the modem quickly enough to not allow the system to appropriately shutdown the modem related processes. Extracting and inserting the modem again will re-send the appropriate system signal and appropriately shutdown and restart the modem related processes.

Replacement procedure

3.2

Replacing an IDU unit g Pay attention to pull out the units, because no special tool is available.

3.2.1

Controller unit replacement The replacement of the Controller unit can be hot-swap or cold-swap. The spare controller must be a "clone" of the Controller unit to be replaced. "Clone" means that the same versions of software components (Application, Kernel, FPGA of the equipped units etc.) reside in the same banks as are in the Controller being replaced.

☞ If the spare controller has different versions of the software components and comes from IDU with different Master I/O equipped as to the Controller unit to be replaced, insert the spare Controller unit (No mismatch alarm will appear and the Reprogramming screen will shows correctly the running version), upgrade all the SW components different and FPGA controller and Master I/O with FTP and finally modify the alarm masking, if it has been modified as to the defualt version (the modified alarm masking resides only in the Controller unit).

☞ The system is designed so as not to lose link on a Controller unit hot-swap.

Consequently, the framer FPGA on the Master IO card is not reprogrammed, when a new Controller is hot-swapped. The check for a mismatch is only valid and done at the time the Master IO FPGA is being programmed.

Case 1: Hot-swap When the Controller is hot-swapped (or warm booted) a copy of the system configuration (kept in the equipment, apart from the Controller unit) is loaded to the new Controller unit. So the IP address and other configuration data are preserved from the old Controller unit. 1. Remove the failed Controller unit. 2. Insert the clone spare Controller unit. Automatically will start the reboot of the equipment. 3. Modify the alarm masking, if it has been modified as to the defualt version. (the modified alarm masking resides only in the Controller unit). Case 2: Cold-swap When the equipment power is turned off, the Controller is replaced and power is turned on, the configuration is loaded from the new Controller unit. So the IP address and other configuration data are loaded from the last configuration stored in the new Controller FLASH memory. If the system configuration stored in the new controller card is desired (e.g. IP address), the system should be powered off before the new controller is inserted. 1. 2. 3. 4.

Power off the equipment. Remove the failed Controller unit. Insert the clone spare Controller unit. Power on the equipment. Automatically will start the reboot of the equipment.

Battery replacement g The battery might explode if not replaced properly. Replace only with the same type or with an equivalent one recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions. Panasonic is the battery manufacturer of the (Part Number: 2032). Disposal instructions are available on the Panasonic website. Please dispose in accordance with local laws. These instructions state how to replace the battery on the Controller Unit in the IDU. It may be necessary to replace the battery after a “Low Battery Voltage” alarm (alarm code 23). A “Low Battery Voltage” alarm code is usually generated when the battery’s charge is depleted due to usage or ageing, or because the battery contacts are slack. Both causes are dealt with below. Before You Begin Before starting the replacement procedure make sure that the following items are available: – – – –

Small flat head screw driver Small needle-nose pliers Panasonic CR2032 or equivalent battery Electrostatic Discharge (ESD) safe workspace

Replacement Procedure 1. Handle the Controller Module in an ESD safe work area. 2. Remove the Controller Module from the IDU chassis by unscrewing the thumbscrews on either side of the card, as indicated in Figure 8. Move the thumbscrews to the threaded holes indicated in Figure 8. If the threaded hole closest to the ground stud is not accessible, the ground stud may be used in its place. Grasp the thumbscrews and pull the Controller Module assembly straight out from the chassis.
