The CISCO3845-AC-IP is the Cisco 3845 integrated services router with an AC-IP power supply for inline power to IP phones. The 3 RU chassis holds four network module slots, against two on the 2 RU Cisco 3825. It takes up to two double-wide NMD or NME-XD modules and two EVM-HD modules.
AC-IP input current is 8 A at 110 V or 4 A at 230 V, with a startup current of 50 A maximum for one cycle. Output is 300 W for the system and 360 W (-48 V) for IP phones. The redundant supply is internal, in AC, AC-IP or DC form. AC power dissipation with IP phone support is 555 W (1890 BTU/hr) for the system and 360 W (1128 BTU/hr) for the phones.
The chassis measures 5.25 x 17.25 x 16 in. and weighs at least 45 lb. Fan tray, motherboard and power supplies are field-replaceable on the 3845. Fixed ports are two Gigabit Ethernet and one SFP slot, with four HWIC slots, two AIM slots, four PVDM slots and Cisco IP Base software. The CISCO3845-DC router is the DC-powered 3845, and the CISCO3825 router is the 3825 with AC power. See also Cisco routers.
