The 3 RU Densit? 3 Frame can simultaneously process 3G, HD, SD and analog video, as well as AES and analog audio and can be fitted with 3 RU and 2 RU Densit? modules (using card extenders). Its front-opening frame features dual hot-swappable power supplies (PSUs) and fans. Modules for the air-cooled frame are also hot swappable, and replacement modules can be configured automatically. All modules, redundant PSUs and fans are monitored to deliver status via GPI or an Ethernet port. Front panel multicolor LEDs provide status reporting, while a controller card allows card adjustments from the front panel.
