This is the DC-powered configuration of the 3-rack-unit 3845 integrated services router, shipped with Cisco IP Base software. The DC input accepts 24 to 60 VDC, auto-ranging and either polarity, drawing 18 A at 24 V or 7 A at 60 V, with start-up current of up to 50 A for under 10 ms. System output is 300 W, power dissipation is 460 W (1,570 BTU/hr), and an internal AC, AC-IP or DC redundant power system can be added.
Fixed connectivity is two 10/100/1000 RJ-45 Gigabit Ethernet LAN ports and one SFP slot for fibre Gigabit Ethernet. Expansion comes from four network-module slots (NM, NME, NME-X, NMD, NME-XD and EVM-HD types), four HWIC slots that also take VIC, VWIC and WIC cards, two AIM slots and four PVDM2 slots for voice DSPs.
Default memory is 64 MB of Compact Flash and 256 MB of ECC DDR SDRAM, expandable to 256 MB of Compact Flash and 1 GB of DDR SDRAM. The chassis measures 5.25 x 17.25 x 16 in and weighs at least 45 lb. The 300 W AC supply for this chassis family is the 3845 300 W AC power supply.
