On the M40 Internet router, the Routing Engine module resides in a metal housing at the
back of the chassis, below the fans, in a compartment behind the card cage (see Figure
61 on page 173).
The M40 router supports three Routing Engine models: RE-M40 (RE1), RE-333 (RE2),
and RE-600 (RE3).
All M40 routers shipped before mid-2001 had RE-M40 Routing Engines. All M40 routers
shipped after mid-2001 have the RE-333 Routing Engine and housing. You could also
upgrade to the RE-600 (RE3) Routing Engine.
The RE-333 and the RE-600 Routing Engines share the same housing, which is different
from the RE-M40. Therefore, if you want to upgrade from an RE-M40 to an RE-333 or
RE-600, you must also upgrade the Routing Engine housing.
