Applies to IRFU deployments only.
Perform this task to replace IRFU components in the field (Figure 110).
Before removing or replacing a main component, wear an ESD wrist strap and attach its

IRFUs ship fully assembled per customer’s ordered options. Figure 110 identifies all field-
replaceable parts.
