Power failure protectionEven during a power failure, all important configuration and calculation data are stored in the non-volatilememoryTime setting is sustained during a power failure of 2 days with the help of the backup battery and resetafter 2 days are elapsed.(10) Wiring distanceaThe distance is called the network diameter.bcdIntegrated management systemDistance DMS and centralized controllersDistance cannot exceed 1000m (3280ft) from the DMS to the end of the centralizedcontroller.c + d + e = < 1000m (3280ft)eDirect distance between DMS and hub/repeater (no use of switch technology)Since DMS supports 10 Base-T Ethernet connection, direct distance from the DMS to the first repeater orupper-layer device cannot exceed 100m(328ft) (IEEE 802.3). The number of cascaded hub/repeaters in thenetwork diameter cannot exceed maximum 4 to extend communication length.That is, the network diameter cannot exceed 500m(1640ft).Maximum length of each node a , b, c, d and e = 100m(328ft)ab c d eRepeaterMaximum number of repeater = 477
