This article explains some possible reasons behind MPC 5E card not powering up on Juniper MX platforms.

1. MPC 5E cards only support enhanced control boards (SCBE / SCBE2) on MX platforms. Verify the generation of control board installed on the chassis:

   show chassis hardware

2. Once control board is verified, check if there are DPC modules installed, as MPC 5E would not work with DPC linecards (except Multi-service DPC). The above command can be used to check the existing linecard's families as well.

3. Once linecard families are verified, check the network-services configured on the device: 

   show chassis network-services  << run this command on both the routing-engines

4. Check the network-services from the RE shell from both of the routing-engines: 

   start shell
   sysctl -a | egrep  netsvc 

   
   On MX240, MX480, and MX960 routers, MPC5E powers on only if the network-services mode on the router is configured to either enhanced-ip or enhanced-ethernet. On MX2010 and MX2020 routers, only enhanced-ip is supported.

   On checking from the shell, netsvc value of 2 indicates enhanced-ip as the network-services.
