Enterasys Networks XSR-1850 Two fans External power source connector One PMC slot for PPMC card

The hardware components for the XSR-18xx modules vary slightly to meet the performance level for each module. The XSR-1850 is an enhancement of the XSR-1805 consisting of the following additional features:

•Two fans

•External power source connector

•One PMC slot for PPMC card

•19” 1.5 U rack-mount chassis

•64 MB of DRAM

Due to the large difference in performance levels, the XSR-3250 hardware components vary quite significantly, when compared to the XSR-18xx modules. The main differences include the following:

•Different processor with two CPU cores

•Different hardware encryption accelerator

•Two extra NIM Carrier Cards (NCC) slots with two NIM slots on each card

•One extra Ethernet port connected to both a miniGBIC module and a RJ45 connector

•Dual load-sharing power supplies

•Redundant fans

•256 MB of DRAM

XSR NIMs will operate on all three XSR modules.
