Chapter 8 Replacing Cisco ASR 1000 Series Routers
Removing and Replacing a SPA Interface Processor
Removing and Replacing a SPA Interface Processor
The Cisco ASR 1006 Router supports three SPA Interface Processors (SIPs) and the ASR 1004 Router supports two SIPs and shared port adapters (SPAs). Online insertion and removal (OIR) is supported on the SIPs and SPAs.
Note For detailed information about SIP and SPA software commands such as activating and deactivating SIPs, prepare for online insertion and removal of SPAs, and activate and deactivate configuration examples, see the Cisco ASR 1000 Series Aggregation Services Routers SIP and SPA Hardware Installation Guide.
Note The embedded shared port adapter interface processor (SIP) on the Cisco ASR 1002 Router does not support online insertion and removal. However, the SPAs on the Cisco embedded
Caution When removing or replacing SPAs, make certain that all the screw fasteners on each card and each SIP are screwed in tightly to prevent accidental removal of another card. Each SIP has two screw fasteners per slot and each SPA has two screw fasteners.
We suggest you have the following tools and parts readily available for installation of the SIPs and SPAs:
•Number 2 Phillips or a
•Shared port adapter interface processor (SIP)
•Shared port adapters (SPAs)
•Cables
•Your own
•Antistatic mat or surface, or static shielding bag
If you need additional equipment, contact a service representative for ordering information.
Electrostatic Discharge Prevention
Electrostatic discharge (ESD) damages equipment and impairs electrical circuitry. ESD occurs when printed circuit boards are improperly handled and results in complete or intermittent failures.
Each SPA circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage. The SIP and SPAs consist of a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier.
When a subslot is not in use, a SPA blank filler plate must fill the empty subslot to allow the router to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the installed modules. If you plan to install a SPA in a subslot that is not in use, you must first remove the SPA blank filler plate.
