The CISCO851-K9 is the Cisco 851 Ethernet to Ethernet router in the Cisco 850 Series. Its WAN link is 10/100 Mbps Fast Ethernet, and the LAN side is a 4-port 10/100BASE-T switch with autosensing MDI/MDX for auto-crossover. The 851 has no 802.11b/g radio, which is the difference from the 851W models in the same table.
Memory is fixed at 64 MB DRAM and 20 MB flash, both default and maximum. The console port is RJ-45, and the LEDs are PPP, VPN, ADSL, WLAN and LAN. Security features include a Stateful Inspection Firewall and IPSec VPN support, and setup runs through the Cisco Router and Security Device Manager (SDM) web tool.
The external power supply takes 100 to 240 VAC at 50 to 60 Hz, with a maximum output of 26 W at 5 and 12 V. Browse more small-office models in Cisco routers.
