Power supplies

If a power supply for one of the TCS crates fails, the time to change it can be many hours depending on the conditions. In some crates the supply sits well hidden inside and requires all cables to be disconnected and the crate to be taken out completely. To avoid loss of many hours of observing time, a number of standard industry supplies has been purchased, and a design was made to require just turning some switches to change to a spare supply. The most critical crate that handles most of the input/output has got a new spare supply installed and all cables prepared for the switches. The TCS main crate will make use of a dedicated, still unused spare. The switches are planned to be installed in the near future. After this, it will only take a few minutes to change to the spare supply for these two critical crates. The crates on the telescope have modular supplies at the front that are easily replaced in case of a failure.
