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 40).
The M40 router supports three Routing Engine models: RE-M40 (RE1), RE-333
(RE2), and RE-600 (RE3). See Table 32 on page 128.
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.
Effective July 15, 2001, the RE-M40 Routing Engine was replaced by the
NOTE:
RE-333 Routing Engine, which was made available with JUNOS software, release
4.2. After July 15, 2004, the RE-M40 Routing Engine is no longer supported. See
"Routing Engine Characteristics Per Routing Platform" on page 128.
