M40 Router Routing Engine Location
Figure 40 shows the location of the Routing Engine on the M40 router.
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.
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.

NOTE: Effective July 15, 2001, the RE-M40 Routing Engine was replaced by the 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.

If you upgrade the Routing Engine housing, the PCMCIA card slot is not accessible and you must use the LS-120 PC card. If you want to install a new version of the JUNOS software, you must use the LS-120 drive.
You can replace the entire Routing Engine housing or just the Routing Engine.
