Cisco 7000 Series Routers - The 7204VXR, 7206VXR and nonVXR Models
Nearly
all 7200 equipment, from complete bundles to individual components and
replacement parts, are available within 24 hours, and we respond
to quote and information requests promptly.
7200
series routers are typically
provisioned
with single or dual AC or DC power supplies, a network processing engine CPU (NPE),
an IO card (which includes external storage and often one or more fast ethernet
or gigabit ethernet ports), and optional port adaptors (PA) providing a variety
of routing and trunking capabilities, as well as some content modules. The 7204
and 7206 versions themselves differ only in the number of PA slots - 4 slots in
the 7204 and 6 in the 7206. A
large number of PA cards exist to populate these slots. Larger
routers (7246, 7300, 7500 - such
as the 7507 - and 7600) are also available.7200XR versus nonVXR: An
important choice in selecting a 7200 series routers is VXR versus nonVXR, and
NPE, IO, and PA cards. NonVXR units process about .6 GBPS of bandwidth - about
half that of the VXR, albeit at a much lower price. But a number of the PA
adaptor cards and the faster NPE cards only work in the VXR version (for
some PA cards, VXR compatibility depends on firmware version.) The
NPE-300, NPE-400, NSE-1, NPE-G1 all work only in the VXR version, while the
nonVXR supports the slower processing engines NPE-100, NPE-150, NPE-200,
NPE-225.
Choosing an IO card principally involves a decision about ethernet
capabilities. The basic IO card has no ethernet ports, so a PA ethernet card
would be required, while an IO-FE and IO-2FE have respectively 1 and 2 10/100
ethernet ports. A gigabit IO cards are also available. Choosing an IO card with
onboard ethernet ports frees up PA slots, so your choice of IO card may depend
on how many PA
cards you plan to install.
NPE Card Selection: The most important configuration choice in
provisioning your 7200 router is the network processing engine - the router's
CPU. For nonVXR units the choices are the NPE-150, 200, and 225, with the
NPE-225 the clear choice because of its faster processor. For VXR units, the
processing abilities of the three main boards vary substantially: NPE-300 (240
MBPS), NPE-400 (320 MBPS), and NPE-G1 (800 MBPS) and NPE-G2 (1600 MBPS). Prices
also vary dramatically, and for most uses the NPE-300 or 400 is sufficient. An
extra feature of the G1/G2 is that they have 3 10/100/1000 built-in ethernet
ports, so no IO card is needed. For

The table below shows the various NPE, IO, storage, and PA cards available for the 7200 line. Research details on each card carefully to determine suitability and compatibility for your application and other hardware.

Note that higher-capacity NPE CPU cards and PA cards are VXR-only compatible.
