Field-Replaceable Units in an EX4600 Switch
Field-replaceable units (FRUs) are components that you can replace at your site. The
EX4600 switch FRUs are hot-insertable and hot-removable:you can removeand replace
them without powering off the switch or disrupting the switching function.
CAUTION: Replace a failed power supply with a blank panel or new power
supply within one minute of removal to prevent chassis overheating. The
switch continues to operate with only one power supply running. Replace a
failed fan module with a new fan module within one minute of removal to
prevent chassis overheating. Do not operate the switch with missing FRUs
for longer than one minute.
Table 4 on page 6 lists the FRUs for the EX4600 switch and actions to take before
removing them.
