Push the jumper assembly onto the pins with firm but reasonable force.
Ensure that the bus connectors make contact with the cabinet connecter
and that the jumper assembly fits snugly against the cabinet. Make sure
that neither of the locking latches slips between the cabinet and the edge
of the jumper assembly.

Locate the ac power cable and plug it into the receptacle at the bottom of
the input jumper assembly as shown in Fig. 4-8. DO NOT plug it into the
ac source until all system installation tasks have been completed and the
system is ready to be initialized. For versions equipped with a power
switch, do not switch to the ON position until you are ready to power up
the system.
Installing the Terminating Jumper Assembly
Each cabinet lineup requires one terminating jumper assembly. This assembly
is always installed on the last cabinet in a lineup, that is, the right-most
cabinet as viewed from the front.
When cabinets are added to an existing system, refer to 'Adding a Cabinet to
an Existing System', later in this part, for the connection procedure.
(1)
Install the bottom hingepin on the terminating jumper assembly using
the 5/64 inch Allen wrench as shown in Fig. 4-7. The screw is provided
in a plastic bag taped to the jumper assembly.
IMPORTANT: Be certain that you install the bottom hingepin before
installing the jumper assembly on the cabinet. Otherwise, installing the
pin will be very difficult.
(2)
Carefully align the assembly with the alignment pins on the cabinet.
The pins are very sharp and may cause injury.
(3)
Push the jumper assembly onto the pins with firm but reasonable force.
Ensure that the bus connectors make contact with the cabinet connector
and that the jumper assembly fits snugly against the cabinet. Make sure
that neither of the locking latches slips between the cabinet and the edge
of the jumper assembly.

Snap on the two locking latches.
