3.
Pull the cover straight off the chassis.
CAUTION:
To maintain proper airflow and provide electromagnetic shielding,
do not operate the router without the rear component cover in place.
Removing the SFMs
The router can have an SFM in each of the slots labeled
SFM 0
and
SFM 1
at the rear of
the chassis, as shown in “M40e Chassis Description” on page 8. Each SFM weighs
approximately 5 lb (2.3 kg).
To remove an SFM (see Figure 42 on page 87):
1.
Place an electrostatic bag or antistatic mat on a flat, stable surface.
2.
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.
3.
Loosen the thumbscrew on each ejector locking tab (shown in “M40e SFM LEDs” on
page 23), using a Phillips screwdriver if necessary.
4.
Pull the end of each ejector handle outward until it is nearly perpendicular to the SFM
or CFEB-E faceplate.
5.
Grasp the ejector handles and pull firmly to slide the SFM or CFEB-E about halfway
out of the chassis.
6.
Place one hand under the SFM or CFEB-E to support it, slide it completely out of the
chassis, and place it on the antistatic mat or in the electrostatic bag.
CAUTION:
When an SFM or CFEB-E is out of the chassis, do not hold it by
the ejector handles. They cannot support its weight.
Do not stack SFMs or CFEB-Es on top of or under other components. Place
each one individually in an electrostatic bag or on its own antistatic mat
on a flat, stable surface.
If a second SFM is installed, repeat the procedure to remove it.
