How To Work With Fault Management To Keep Network Health Modern day computing devices use networks that are ubiquitous in nature. From the wireless home network to the intricate business network, IT administrators manage network resources and wellness. In accordance with change requirements, during the majority of network operation, network communications have the ability to work reliably and most of the IT responsibility is to add or remove unnecessary components. When faults do occur, this is typically rare, where the IT would have to respond immediately in order to prevent a complete shutdown, so decisions need to be appropriately. During such a time, IT must have the correct tools for fault management to be able to maintain the health of their system. Causes of Network Faults The initial step to fault management is to be aware of the possible causes of the error. For any fault that takes place, there is a closed set of possible causes and understanding these will help the IT technician uncover the problem more efficiently. A connector problem is frequently the first thing that is looked for because these are normally the likely cause of the failure. These represent the parts of a system with the lowest MTBF. A fault will appear if a connector no longer has a positive connection which essentially means it has worn out. Damage to the cable is another source for a fault in a wired system. If a cable is somehow bent or smashed a fault will in the end occur even though cables are usually installed to isolate them from activity in the facility. Yet another possible cause is the addition of an electronic noise source. If a high powered motor is placed too near a network component or cables, the noise coming from that motor could disrupt the network signal. In each of these scenarios, the IT technician must locate the fault area and locate the cause. This is generally the most difficult part of fixing the fault. Once the malfunctioning region is located, the IT tech would replace the cable or remove the source of the noise which is easy compared to other issues that could occur. Fault Localization Localizing faults can still be straightforward even though factory installation could consist of miles of cables and hundreds of network components. Positioning the network components tactically is key, where they are fundamentally acting as gatekeepers. If a failing occurs between Component A and Component B, then a fault between the two will be recorded at one and not the other. The detecting component will signal an alarm and send it via SNMP to the IT administrator for rapid response. The administrator can classify the different types of alarms in accordance with severity levels and the position within the facility. Fault Correction In simple, non-critical platforms, the repair can be as easy as replacing the cable between the components and re-testing the system. Alternate cable routing is one other strategy if this doesn't necessarily correct the issue. Critical systems will have repetitive routing. An alternate route can be used in these types of systems where if a problem is noticed, the pathway can be switched to allow the system to still Centina Systems, Inc.

However, the loss of the faulted route can still affect communications throughput, and will have to still be repaired at some point. Management Software One of the most useful innovations toward fault management would be the use of visualization software. This normally presents an actual map of the facility and can color code the element that signals the alarm, possibly with a flashing red icon. Even an untrained technician would be able to say for certain where the error is and which cable is involved and go quickly to the source of the problem, even if they themselves can not correct it. This is a big improvement over standard alarm systems, which simply show the name of a faulted component, leaving the specialist to try to match the name to the region, all the while losing precious time. Probably the most important parts of an efficient management systems is the management software to help find critical problems rapidly to get the system back up and running proficiently.
