Cisco NCS 5504 User Manual

Always handle the MPA by the carrier edges and handle; never touch the MPA components or connector pins
(See the figure below).
Caution
When a bay is not in use, a blank MPA Slot Filler must fill the empty bay to allow the router or switch to
conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across
the installed modules. If you plan to install a MPA in a bay that is not in use, you must first remove the blank.

Online Insertion and Removal
Cisco IOS XR Software 6.6.1 and later releases support online insertion and removal (OIR) of Cisco NCS
5500 series modular port adapters (MPAs).
Caution
Cisco NCS 5500 series modular port adapters (MPAs) support online insertion and removal (OIR). Modular
port adapters (MPAs) can be inserted or removed independently from the modular line card (MLC). OIR of
a MLC with installed modular port adapters (MPAs) is also supported.
Modular port adapters (MPAs) support the following types of OIR:
• Soft OIR
Soft OIR uses the IOS XR hw-module subslot rack/slot/subslot reload, hw-module subslot
rack/slot/subslot shutdown, and no hw-module subslot rack/slot/subslot shutdown commands to
complete online insertion and removal.
• Managed OIR
A managed online insertion and removal of Modular port adapters (MPAs) is comprised of the following
steps:
• Shut down the MPA with the hw-module subslot rack/slot/subslot shutdown command.
