With nothing to go on, Sean ordered in nine complete sets of hardware and paid the eye-watering extra cost to get the kit delivered same day. The next morning, armed with a bulging site pack full of gear, he hopped on a train to London and set off on a voyage into the unknown. He was at least a little familiar with the client's site and, upon arrival, headed directly to the location where the stricken devices had been installed. They were all working perfectly. Apart from one, which just needed to be switched on. The client turned up shortly after, wanting to know how long the job was going to take.
