standard 19 in. rack. Before using any of these mounting methods, record the

serial number from the back of the backplane.

Each set of mounting instructions in this document includes an instruction to

connect the protective earth (PE) ground terminal on the cFP-BP-

backplane to

the system safety ground. The backplane PE ground terminal has the following

symbol stamped beside it: . Connect the backplane PE ground terminal to the

system safety ground using 14 AWG (1.6 mm) wire with a ring lug. Use the

5/16 in. panhead screw shipped with the backplane to secure the ring lug to

the backplane PE ground terminal.
