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 ASR1000-SIP10 do
support online insertion and removal.
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 3/16-inch flat-blade screwdriver
• Shared port adapter interface processor (SIP)
• Shared port adapters (SPAs)
• Cables
• Your own ESD-prevention equipment or the disposable grounding wrist strap included with all
upgrade kits, field-replaceable units (FRUs), and spares
• 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.
