Understanding Hardware Redundancy of QFX5100 Device Components and

Functionality

Field-replaceable units (FRUs) are components that you can replace at your site. The

QFX5100 device FRUs are hot-insertable and hot-removable: you can remove and replace

one of them without powering off the switch or disrupting the switching function.

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 10 on page 75

lists the FRUs for the QFX5100 device and actions to take before

removing them.

Required Action

None. We recommend that you disable the interface using the set interfaces

interface-name disable command before you remove the transceiver. See

If you have a Juniper Care service contract, register any addition,

change, or upgrade of hardware components at

https://www.juniper.net/customers/support/tools/updateinstallbase/

to do so can result in significant delays if you need replacement parts. This

note does not apply if you replace existing components with the same type

of component.
