At Cable Television Company H, it was time to replace the UPS that had been in use until now. Mr. N of the facilities department sorted out the problems with the existing system and summarized the requirements for a new UPS.
The servers and broadcasting equipment used to provide services are concentrated in the server room. In order to reduce the negative effects of heat generated by the broadcasting equipment, the server room is always air-conditioned to maintain a constant room temperature. However, if the air conditioner breaks down or otherwise stops working, the temperature in the server room rises, which can cause equipment failure. However, the server room is basically unmanned, and there are many unmanned stations, so it was difficult to respond to any problems in a timely manner. (Mr. N)
In recent years, cable TV companies have also developed Internet provider businesses, and Mr. N describes his company's services as follows.
In addition to our cable television business, we also provide Internet and other telecommunications infrastructure services, so we cannot shut down our equipment 24 hours a day, 365 days a year.
We can perform maintenance work such as replacing UPS batteries without stopping the power supply, but this is not the case when it comes to replacing the UPS itself. In the case of maintenance that requires service interruption, such as equipment replacement, it is necessary to notify the customer in advance and to adjust the service schedule. We needed to think of measures to prevent possible problems before they occur and to lighten the maintenance load. (Mr. N)
Mr. N, who was stuck in his efforts to gather information, explained his situation to a person in charge at SANYO DENKI CO., LTD. and asked for advice.
The SANYO DENKI CO., LTD. representative proposed a combination of the SANUPS A23C and LAN Interface Card as the optimal solution for Company H. Mr. N, who was strongly attracted to this proposal, said the following:
"With SANYO DENKI CO., LTD. 's LAN Interface Card, we can instantly detect power supply abnormalities and send an email to the person in charge's PC or mobile phone. We can also monitor the status of the power supply and batteries in real time via the network. This means we can significantly reduce the number of visits to the site, which in turn cuts maintenance man-hours." (Mr. N)
Another key point, he says, was the ability to measure humidity and temperature in the server room by combining an optional temperature and humidity sensor.
"We were originally planning to install a separate monitoring system to monitor the room temperature in the server room, but by simply connecting a temperature and humidity sensor to LAN Interface Card, we can now remotely check the surrounding temperature and humidity in real time. Sensors can be easily expanded by simply connecting them with a LAN cable, and up to 16 points can be connected, allowing for detailed monitoring," said Mr. N.
"The deciding factor this time was the proposal to install an external bypass circuit. An external bypass would enable us to replace the UPS while continuing to supply power to the server. We consulted with several other companies, but only SANYO DENKI CO., LTD. 's staff was able to make a proposal that looked into the future. This proposal was based on a thorough understanding of our situation, so we felt it was very reassuring." (Mr. N)
Thus, Company H decided to adopt the SANUPS A23C and LAN Interface Card. This enabled them to monitor the power and temperature status of each location.
"We have already decided to use this system in our new unmanned station building. We appreciate the proposal that fully addressed our requests. We would like to continue consulting with SANYO DENKI CO., LTD. on various matters." (Mr. N)
