CAUTION: Replace a failed power supply with a blank panel or new power supply
within one minute of removal to prevent chassis overheating. The router 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 router with missing FRUs for longer than one minute.
NOTE: If you have a Juniper J-Care service contract, register any addition, change, or upgrade
of hardware components at
https://www.juniper.net/customers/csc/management/updateinstallbase.jsp . Failure 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.
NOTE: Before removing the optical transceivers, we recommend that you disable the interface
using the set interfaces interface-name disable command. See “Disconnecting a Fiber-Optic
Cable from an ACX5000 Router” on page 130.
