Figure 15. Removing the disk drive backplane
11. Lift the disk drive backplane out of the chassis.
12. If the removed part is used again, place the part on an electrostatic discharge (ESD) mat.
Replacing the base function disk drive backplane in the 9009-41A, 9009-41G, 9009-42A,
9009-42G, or 9223-42H system
To replace the base function disk drive backplane in the system, complete the steps in this procedure.
Procedure
1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged
into a ground jack or connected to an unpainted metal surface. If not, do so now.
2. The chassis has two alignment pins and several brackets (A) to secure the disk drive backplane. Using
the disk drive backplane touchpoint (B), thumbscrew (C), and alignment pins (A), insert the disk drive
backplane into the chassis as shown in the following figure.
Slide the disk drive backplane to the side in the direction that is shown so that the disk drive backplane
slides under tabs in the chassis.
