<P> Modular / blade systems with dedicated management modules often offer a dedicated OOB Ethernet port or Lights out management port . </P> <P> A complete remote management system allows remote reboot, shutdown, powering on; hardware sensor monitoring (fan speed, power voltages, chassis intrusion, etc .); broadcasting of video output to remote terminals and receiving of input from remote keyboard and mouse (KVM over IP). It also can access local media like a DVD drive, or disk images, from the remote machine . If necessary, this allows one to perform remote installation of the operating system . Remote management can be used to adjust BIOS settings that may not be accessible after the operating system has already booted . Settings for hardware RAID or RAM timings can also be adjusted as the management card needs no hard drives or main memory to operate . </P> <P> As management via a serial port has traditionally been important on servers, a complete remote management system also allows one to talk with the server through this port (SOL console). </P> <P> As sending monitor output through the network is bandwidth intensive, cards like MegaRAC use built - in video compression (versions of VNC are often used in implementing this). Devices like Dell DRAC also have a slot for a memory card where an administrator may keep server - related information independently from the main hard drive . </P>
