module to support it and slide it completely out of the chassis.

9. Place the RE module in the anstac bag or on the anstac mat.

CAUTION: Do not stack hardware components on one another aer you remove

them. Place each component on an anstac mat resng on a stable, at surface.

(SF module) installed in the chassis without an RE module for extended periods of me. If you

remove an RE module, install a replacement RE module as soon as possible.

Figure 71 on page 227 shows removing an RE module from an EX9204 switch. The procedure is the
