Installing and Removing a SPA
This chapter describes how to install or remove SPAs on the Cisco 10000 series router. This chapter contains the following sections:
•
Online Insertion and Removal of a SPA
Handling SPAs
Each SPA circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage. Before you begin installation, read the "Preparing to Install a SIP or a Shared Port Adapter," chapter for a list of parts and tools required for installation.
Caution
When a subslot is not in use, a SPA blank filler plate must fill the empty subslot 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 SPA in a subslot that is not in use, you must first remove the SPA blank filler plate.
Figure 6-1 Handling a SPA
Online Insertion and Removal of a SPA
The Cisco 10000 series router supports OIR of a SPA independently of removing the SIP. This means that a SIP can remain installed in the router with one SPA remaining active, while you remove another SPA from one of the SIP subslots. If you are not planning to immediately replace a SPA into the SIP, then be sure to install a blank filler plate in the subslot. The SIP should always be fully installed with either functional SPAs or blank filler plates.
The interface configuration is retained (recalled) if a SIP or SPA is removed and then replaced with one of the same type.
If you are planning to remove a SIP along with its SPAs, then you do not need to follow the instructions in this section. To remove a SIP, see Chapter 5, "Installing and Removing a SIP".
Deactivating a SPA
Although graceful deactivation of a SPA is preferred using the hw-module subslot shutdown command, the Cisco 10000 series router does support removal of the SPA without deactivating it first. Before deactivating a SPA, ensure that the SIP is seated securely into the slot before pulling out the SPA itself.
If you are preparing for an OIR of a SPA, there are no standard interfaces to be shut down prior to deactivation of the SPA. The hw-module subslot shutdown command automatically stops traffic on the Gigabit Ethernet interfaces and deactivates them along with the SPA in preparation for OIR. In similar fashion, you do not need to independently restart any Gigabit Ethernet interfaces on a SPA after OIR of a SPA or SIP.
Note
To deactivate a SPA and all of its interfaces prior to removal of the SPA, use the following command in global configuration mode:
Reactivating a SPA
If you deactivate a SPA using the hw-module subslot shutdown global configuration command and again reactivate it without performing an OIR, you need to use the no hw-module subslot shutdown global configuration command to reactivate the SPA and its interfaces.
To activate a SPA and its interfaces after the SPA has been deactivated, use the following command in global configuration mode:
Verifying the Status of a SPA
When you deactivate a SPA, the corresponding interfaces are also deactivated. This means that these interfaces will no longer appear in the output of the show interface command.
To verify the deactivation of a SPA, enter the show hw-module subslot oir command in privileged EXEC configuration mode. Observe the Operational Status field associated with the SPA that you want to verify.
In the following example, the SPA located in subslot 1 of the SIP in chassis slot 7 is administratively down after entering the hw-module subslot shutdown powered command:
Router(config)# hw-module subslot 7/1 shutdown poweredPerforming request on SPA 7/1 in jacket card in slot 7Router(config)# exitRouter# show hw-module subslot 7/1 oirModule Model Operational Status------------- -------------------- ------------------------subslot 7/1 SPA-5X1GE-V2 admin downRouter#Installing a SPA in a SIP

Optical Device Maintenance
Any contamination of the fiber connection can cause failure of the component or failure of the whole system. A particle that partially or completely blocks the core generates strong back reflections, which can cause instability in the laser system. Inspection, cleaning, and reinspection are critical steps to take before making fiber-optic connections.
Cleaning Optical Devices
See Inspection and Cleaning Procedures for Fiber-Optic Connections for information on cleaning optical devices.
Checking the Installation
This section describes the procedures you can use to verify the SIP and SPA installation, and includes information on the following topics:
•
Verifying the Installation
This section describes how to verify the SIP and SPA installation by observing the SIP LED states, SPA LED states, and the information displayed on the console terminal.
When the system has reinitialized all interfaces, the SIP FAIL LED is off and the SPA STATUS LEDs are green (on). The port LEDs (C/A and A/L) may be green (on), depending on your connections and configuration. The console screen also displays a message as the system discovers each interface during its reinitialization.
Use the following procedure to verify that a SIP and SPA are installed correctly:

Using show Commands to Verify SPA Status
Table 6-1 describes some show commands to verify that SPAs are configured and operating correctly.
SPA Blank Filler Plates
SPA blank filler plates are available to fill an unused SPA subslot.
When a SPA subslot is not in use, a SPA blank filler plate must be installed in the empty subslot to allow the router or switch to conform to electromagnetic interference (EMI) emissions requirements and to allow proper airflow across the SPAs. If you plan to install a new SPA in a subslot that is not in use, you must first remove the SPA blank filler plate.
