Using a Serial Switch to Track Power Supply Conditions at Remote Equipment Sites

Sometimes, it’s hard to tell when there’s been a temporary power outage at a remote network equipment installation site. A temporary power interruption might seem like its not a big deal, but it’s definitely something that a network administrator should know about. Even if all of the devices at the remote site recovered gracefully after power was restored, a temporary power outage could be a good indication of more power problems in the future. That’s why a serial switch with a power cycle alarm can be such a useful asset for network administrators who are concerned about power supply stability at remote network equipment sites.

When the power supply at a remote network equipment site hiccups and temporarily ceases to function, it’s often an indication that the power supply may either be inadequate for the load that has been put on it, or that the power supply is getting ready to fail completely. Either way, this is useful information for network administrators who need to ensure that remote network equipment sites will always be online when needed. A temporary power supply failure can be a good indication that it’s time to take a closer look at power requirements at the remote site, or possibly look into a back-up power supply before the existing power supply gives up the ghost completely.

A temporary power supply failure is always something that merits further investigation. Even if the power supply is sound and the devices in the rack appear to have recovered nicely, it’s still worth a second look to make sure that any power spikes that might have occurred before or after the interruption have not damaged other devices in the equipment rack. A serial switch with a power cycle alarm provides network administrators with both a tool to be kept apprised of power supply instability, and a means to communicate with other devices in the equipment rack in order to make sure that they completely recovered from the power supply interruption, and no damage was caused in the process.

When managing remote network equipment sites that are located miles from your central office, it’s vital for network administrators to be able to know exactly what’s going on at that site. It’s a relatively simple matter to keep track of conditions and events when the equipment rack is located nearby, but if you’re dealing with equipment that’s located miles away, a serial console server with a power cycle alarm, as well as other event monitoring and notification features provides administrators with a powerful tool for keeping tabs on conditions at the remote site without the time, expense and trouble of regularly traveling to the rack in person.
