Re: [AFMUG] Data center temperatures

Or if you had 3 or 4 mx960s per cabinet... 38A per power supply x 4 power supplies = 152A. 152A per chassis x 3 = 456A. An MX2020 is fun if running via DC power. ". A total of four PDMs can be installed into a router. Each DC PDM operates with up to nine separate feeds of either 60-amp or 80-amp

Depends on where the temperature sensors are? If we're talking about colocation type cabinets with front-to-rear airflow, and mesh doors on both ends, air intake temperature should be around 20C on the intake side. Or open two-post/relay racks in a room? Hot aisle/cold aisle separated, or
