Figure 87: Removing the Front Impeller Assembly
Removing the M40e Craft Interface from the Front Impeller Assembly
If you are replacing the front impeller assembly and the replacement assembly does not
have a craft interface panel on the front, you must transfer the craft interface from the
removed assembly to the replacement assembly. To remove the craft interface from the
removed impeller assembly:
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.
Place the removed and replacement impeller assemblies top side up on antistatic
mats.
3.
If not immediately transferring the craft interface panel to the replacement assembly,
place an antistatic mat or electrostatic bag on a flat, stable surface to receive it.
4.
Using a Phillips screwdriver, remove the screws from the three semicircular metal
tabs on the back of the craft interface that secure it to the impeller assembly (see
Figure 88 on page 174). Save the screws.
5.
Grasp the ends of the craft interface, pull upward to release the hooks on the back of
it from the windows on the front of the impeller assembly, then pull it toward you to
free the craft interface completely (see Figure 89 on page 174). If not immediately
transferring it to a replacement impeller assembly, place it in the electrostatic bag or
on the antistatic mat.
