During the busy Christmas week last year the IT server room at a large UK hospital was at serious risk of overheating. Despite already having fixed air conditioning in place, the hospital was unhappy with the system's quality and reliability. In accordance with their server room policy (which had philips jersey contingencies ‘built-in'), the hospital's Director of Systems and Operations contacted an air conditioning hire specialist with whom he had formulated a contingency plan. His urgent request for portable air con units was responded to immediately, and any concerns over the server room overheating were swiftly allayed.

The hospital was able to source the air con they required ? from an air con rental specialist that offers a full 24-hour 365-day nationwide service ? within the hour. Because a free site survey had already been performed by the specialist philips jersey team, they knew which mobile air con units would be most appropriate for the room. The temperature was quickly lowered, with no disruption to normal server operations.
Summer temperature threats

Server rooms are not just found in hospitals, of course; most business premises, educational establishments, and public buildings, etc. that use networked computers will have a server room. Wherever the room is located, the temperature there can on average be 10°C higher than the rest of the building. This means the room can overheat quickly in summer.

In the UK, the hottest temperature ever recorded was 37°C (in Kent), which would make the temperature at server rooms there a dangerous 47°C ? inevitably leading to server malfunction. But even during a typical UK summer, when the temperature is usually 20°C, it would still mean a server room temperature of at least 30°C.
About controlled server room access
Very few server rooms house a single server (a server ‘node'). Normally, a number of connected nodes will be housed philips jersey in racks, along with routers and switches, in a room with controlled access.
At larger facilities where there is a server room controlled access policy in place, only server engineers will have right of entry to the room, working there under the direction of the Director of Systems and Operations, or the Production Operations Manager.

Controlled access is essential as an unauthorised employee could compromise the room's temperature accidentally, e.g. by switching off air con units. Some businesses and organisations even have CCTV cameras in place, to protect their server room equipment and the information stored on it.

Access will be provided through use of a code number, swipe card, through signing-in or having an ‘access request' accepted. All employees will be made aware of the facility's server room access policy, in which it is made clear:

1.??? Who is allowed admittance?

2.??? Who is responsible for checking temperatures regularly?

3.??? What the protocol is if the temperature rises?

In fact, such is the potential hazard of high temperatures at some facilities, if a server room temperature climbs to a dangerous level at night or over the weekend, authorised staff can receive an automatic e-mail or text message, alerting them to the problem.
