Compatibility Notes

1. Clock 501-2975 is not supported.
2. The E6000 and E6500 require Clock 501-5365 for a 5:1 clock ratio.
3. The E3x00, E4x00, and E5x00 require Clock 501-5365 for a 5:1 clock ratio if 84MHz system boards are installed.
4. Clock 501-4286 or 501-4946 is supported in the E3x00, E4x00, and E5x00 if the centerplane and all system boards are 100MHz.
5. Clock 501-5365 is supported if 84MHz or 100MHz system boards are installed in the E3x00, E4x00, and E5x00.

E10000 Notes

1. Mixing module speeds within a system is supported.
2. A minimum of one processor per System Board is required.
3. Set the clock multiplier to 2:1 with the command:
   sys_clock -p two-to-one -s -i 100000000
   Caution: Using sys_clock with command line options can crash a running system.
