MX2010 Field-Replaceable Units

 

Field-replaceable units (FRUs) are router components that can be replaced at the customer site (see Table 1). Replacing most FRUs requires minimal router downtime. The router uses the following types of FRUs:

  • Hot-removable and hot-insertable FRUs—You can remove and replace these components without powering off the router or disrupting the routing functions.

  • Hot-pluggable FRUs—You can remove and replace these components without powering off the router, but the routing functions of the system are interrupted when the component is removed.

    Note

    Before you replace most host subsystem components, such as the Control Board and Routing Engine (CB-RE), you must take the host subsystem offline.

    You must power off the Control Board and Routing Engine (CB-RE) before replacing a CompactFlash card or solid-state drive in a Routing Engine.

Table 1 lists the FRUs for the MX2010 router.

Hot-Pluggable FRUs

  • PSM air filter

  • Air filter (lower)

  • Lower cable manager

  • Craft interface

  • Switch Fabric Board (SFB) (if redundant)

  • Backup CB-RE (if redundant)

  • Master CB-RE (if nonstop active routing is configured)

  • Modular Port Concentrators (MPCs)

  • Adapter cards

  • Modular Interface Cards (MICs)

  • Fan trays

  • AC power distribution modules (if redundant)

    Note: A PDM can be replaced without impacting services. However, you must first disconnect it from power. See the PDM replacement procedures listed in Related Documentation.

  • DC (-48 V) power supply modules (if redundant)

  • DC (-48 V) power distribution modules (if redundant)

  • DC (240 VDC China) power supply modules (if redundant)

  • DC (240 VDC China) power distribution modules (if redundant)

  • Universal (HVAC/HVDC) power distribution modules (if redundant)
