Figure 55: Reinstalling the Fan Tray
Reinstalling the Rear Lower Impeller Assembly
The rear lower impeller assembly is located to the left of the circuit breaker box on the
rear of the chassis, as shown in “M40e Chassis Description” on page 8. To reinstall it
(see Figure 56 on page 101):
1.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to one of the ESD points on the chassis. For more information about ESD,
see “Preventing Electrostatic Discharge Damage to an M Series, MX Series, or T Series
Router” on page 232.
2.
Orient the impeller so that the label is on the top. Align the rails on the upper edges
of the impeller assembly with the guides inside the chassis.
3.
Push the impeller assembly up and to the right to start it into the chassis, then slide
it all the way in.
4.
Tighten the thumbscrew at each corner of the impeller cover.
