Many of us have been working from home during the recent pandemic. We recommend that following major Monsoon storms, you have a staff member head to your office to make sure the server room remains dry. The sooner you discover a leak or other issue, the better.
Monsoon Storms can cause...
WATER - In your server/comm room, look for gaps between floor, walls, and ceiling, and around conduit entry paths and terminations. Water will follow cables into rack-mounted and free-standing devices, then pool in low points on the floor. Being a good conductor with little resistance, water lets big current flow where it shouldn't, zapping components in it's path. Many solders, solder paste, flux, and copper trace material tends to corrode when water is introduced. Below is shredded fibrous material that fell from soaked ceiling tiles onto a rack mounted server, thankfully this is not one of our customers.
Water Prevention Tips for Server Room
POWER - Spikes, shorts, brown-outs and outages cause unplanned shutdowns at best, but can damage electronics, destroy data and cause extended downtime for a business. Often caused by lightning strikes or downed power lines, these can also be caused by electricity shorting through water paths, and when networking devices fail they can send power surges through connected cables, frying connected components along the way as shown below.
Tips to Avoid Power Issues
HEAT - Monsoon storms are accompanied by excessive heat. As the surrounding temperature rises, so does the temperature near external walls and inside server rooms, where dust accumulates inside enclosures and airflow around components slows down.
Most electronic components have temperature sensors that notify when limits are exceeded, and can even initiate shutdowns to avoid damage. The best prevention is adequate airflow around the devices in a relatively dust-free environment, with all internal fans working well.
Here is a good thermal design with "cold aisles" supplying conditioned air through hot rack space and "hot aisles" exhausting the resulting heated air. Even a small fan directed at a hot device can provide adequate cooling, but should be used as a temporary measure until a better solution can be implemented.

Monsoon storms can be dramatic and so can the damage they leave behind.
With a little attention before they start, you can protect your infrastructure, data and operations.
