It has a fanless design and features the store and forward switching modes. The fanless design results in minimal heat generation and a high MTBF rating. The switch has an operating voltage range of 110 to 250 Volts DC or 110 to 230 Volts AC. The current consumption rating at 230 Volts is 170 Amps maximum if all the ports are equipped with fiber cables. This switch consumes a total of 31.5 Watts power with a power output of 108 BTU per hour with normal operating conditions. The front side of the MAR1020-99MMMMMMMMMMMMMMMMMMMMMMMMFMMHPH switch has a 3-pin terminal block for the power supply and a 2-pin terminal block for the signalling contact. An RJ 11 socket with a V.24 interface along with a USB interface to connect an auto configuration adapter are present on the front of the switch. All of these ports have their own LED status indicators.
The Hirschmann MAR1020-99MMMMMMMMMMMMMMMMMMMMMMMMFMMHPH rack mount switch can work with both single-mode and multimode fiber cables. It supports both star and line network topologies. The switch comes in a small and compact size with dimensions of 448 millimeters in width, 44 millimeters in height, and 310 millimeters in depth. It can be easily housed inside a 19-inch control cabinet in the system. The enclosure of the switch comes with an IP 30 environmental protection rating. The MAR1020-99MMMMMMMMMMMMMMMMMMMMMMMMFMMHPH rack mount switch comes with a protective coat of paint on its PCB to allow it to withstand applications in extreme industrial conditions. The switch features time synchronization with the SNTP server, and a real time clock with an energy buffer. It also supports manual cable crossing. This switch should not be exposed to sources of high heat.
