“Upgrading and Downgrading the CFEB and CFEB-E” on page 88. To replace the CFEB
or CFEB-E, perform the following procedures:
•
Removing the M7i CFEB and CFEB-E on page 87
•

Removing the M7i CFEB and CFEB-E
To remove the CFEB or CFEB-E (see Figure 32 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.
3.
Press and hold the
ONLINE/OFFLINE
button on the faceplate of the CFEB or CFEB-E
until the green
OK
LED turns off, which takes about 5 seconds.
4.
Loosen the thumbscrew on each ejector locking tab (shown in Figure 4 on page 10),
using a Phillips screwdriver if necessary.
5.
Pull the ends of the ejector handles outward until they are nearly perpendicular to the
faceplate of the CFEB or CFEB-E.
6.
Grasp the ejector handles and pull firmly to slide the CFEB or CFEB-E about halfway
out of the chassis.
7.
Place one hand under the CFEB 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 a CFEB or CFEB-E is out of the chassis, do not hold it by
the ejector handles. They cannot support its weight.
Do not stack CFEBs 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.
