Do not touch any rear terminals while the relay is energized!
The small form-factor pluggable ports (SFPs) are pluggable transceivers. Do not use non-validated
transceivers or install validated transceivers in the wrong Ethernet slot, else damage can occur.
The relay follows a convention with respect to terminal number assignments which are three characters long assigned in
order by module slot position, row number, and column letter. Two-slot wide modules take their slot designation from the
first slot position (nearest to CPU module) which is indicated by an arrow marker on the terminal block. See the following
figure for an example of rear terminal assignments.
