The NG-100G-F2 module can be installed in any slot, except slot 1. After the NG-100G-F2 module has been installed and the Status LED turns green (10-15 seconds), the CPU-5004A module must be installed in the slot to the immediate left of the NG-100G-F2 module. Once the CPU-5004A Status LED turns green (10 - 12 minutes), the module set should be operational.
