    Outstanding Issues with the M40e Router

    This section lists outstanding issues with the documentation.

    • Combinations of PICs—On Juniper Networks routers, you can typically install any combination of Physical Interface Cards (PICs) on a single Enhanced Flexible PIC Concentrator (FPC). With Junos OS Release 6.3, on M5, M10, M20, M40, M40e, and M160 routers, there are some combinations of PICs that cannot be installed together on the same Enhanced FPC. If you are upgrading to Junos OS Release 6.3 on one of the systems mentioned above and have different PIC types on a single FPC, please consult Technical Bulletin PSN-2004-04-005 on the Juniper Networks Support Web site http://www.juniper.net/support/.
    • When inserting the power supply for the M40e router, be extremely careful to ensure that the power supply is fully seated into the midplane.

      Caution: Forcing the power supply into the midplane when the connectors are not aligned will break or bend the connectors.

      To properly install the power supply, follow this procedure:

      1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
      2. Verify that the power switch for each power supply is in the OFF (O) position. On an AC-powered router, the switch for each power supply is on the power supply faceplate. On a DC-powered router, the switches are on the circuit breaker box.
      3. Place one hand under the power supply and grasp a handle on the faceplate with the other hand.
      4. Slide the power supply into the chassis until it reaches the upward curve on the bottom.

      5. Carefully push the power supply in to the connectors on the midplane until it is seated securely.
