Static electricity can damage switch components. Be sure to wear antistatic
straps before handling hardware modules and disk drives.

5. If the DP is still not visible, FRU the entire system, following the
steps in this appendix.
Failure indications may also arise from the following:
• CP/DP uncorrectable Error-Check Circuitry (ECC) error reported by
SNMP trap.
• CP/DP excessive correctable ECC errors reported by SNMP trap.
• CP fan failure reported by SNMP trap.
• CP over temperature reported by SNMP trap.
