    This section shows where the Routing Engines are installed in each router. This section includes the following locations:

    Figure 1 shows the Routing Engine location in the M5, M10, and M20 routers.

    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 3).

    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.

    Note: The Routing Engine RE-M40 has been replaced with RE-333 and RE-M40 is no longer supported.

    See also the End-of-sale and End-of-service Announcement for the M40 routing platform and products at https://www.juniper.net/support/eol/ . End of life (EOL) indicates that the product has been removed from the price list and is no longer available for purchase. End of support (EOS) indicates that no new support contracts are available on these products and the last contract will expire on the EOS date associated with each product. For more information about EOS or EOL products, see the product support notification (PSN) hardware end-of-life announcements.

    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 OS, you must use the LS-120 drive.

    You can replace the entire Routing Engine housing or just the Routing Engine.

    Figure 4 shows the Routing Engine location on the M40e and M160 router.
