Hold the network processor module by its handle, align it with the grooves in the chassis
(not shown) and over its connector, and push it lightly against the chassis wall. (See
Figure 7.)
Gently, without bending the connector pins, push the network processor module into place,
inserting the male network processor module connector into the female network processor
module connector on the motherboard.
Replace the module mounting screw on the end of the network processor module. (See
Figure 7.)
If the module has external rear mounting screws to attach the network processor module to
the rear of the chassis, replace the screws at this time.
Do not overtorque the module mounting screw. The network processor module or the
Reinsert the component tray into the shell, pushing on the back of the tray while at the same
time pressing on the chassis release screw (see Figure 3) with the thumb of your right hand.
Retighten the chassis release screw.
If you have an AC-powered system, plug the system power cord into a 3-terminal,
single-phase power source that provides power within the acceptable range (100–240 VAC,
50–60 Hz, 3.0–1.5 A).
If you have a DC-powered system, rewire the DC-input power supply (40 to 72 VDC) to
the terminal block. The proper wiring sequence is ground to ground, positive to positive,
and negative to negative. (See Figure 17.) After connecting the DC power cables, use a
screwdriver to reinstall the terminal block cover.
After wiring the DC power supply, remove the tape from the circuit breaker switch handle
Turn ON the system power switch. The power LED on the front should go ON.
Check the OK LED on the right side of the front panel (see Figure 1) to verify that it goes
ON after a few seconds delay when booting.
