Installing and Removing a SPA

This chapter describes how to install or remove SPAs on the Cisco CRS-1 router. This chapter contains the following sections:

Handling SPAs

Each SPA is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage. Before you begin installation, read “Preparing to Install a SIP or a SPA,” for a list of parts and tools required for installation.


Caution Always handle the SPA by the carrier edges and handle; never touch the SPA components or connector pins (see Figure 7-1).

When a subslot is not in use, a SPA blank filler plate must fill the empty slot 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 slot that is not in use, you must first remove the SPA blank filler plate.

Installing a SPA in a SIP


Caution The system can indicate a hardware failure if you do not follow proper procedures or you remove a SPA while the software configuration is being applied. After you remove a SPA, wait at least 15 seconds before installing another SPA in the same subslot.

To install a SPA in a SIP, see Figure 7-2 or Figure 7-4 and follow these steps:


Step 1 Locate the guide rails inside the SIP that hold the SPA in place. They are at the top left and top right of the SPA slot and are recessed about an inch, as shown in Figure 7-2 or Figure 7-4.


Note Insert the SPA so that the blank side of the SPA is facing up, when being inserted into a SIP that is not installed in the Cisco CRS-1 router. The blank side of the SPA should be facing to the right when the SPA is inserted into a SIP that is installed in the Cisco CRS-1 router. Note the orientation in Figure 7-4.


Step 2 Carefully slide the SPA all the way into the SIP until the SPA is firmly seated in the SPA interface connector. When fully seated, the SPA might be slightly behind the SIP faceplate.

Step 3 After the SPA is properly seated, fasten the SPA in place with the captive screws, as shown in Figure 7-3 or Figure 7-5. Tighten the locking thumbscrews on both sides of the SPA to a torque of between 8.3 and 11 inch-pounds (94 to 124 N-cm). Do not overtighten.


 

Removing a SPA from a SIP


Caution The system can indicate a hardware failure if you do not follow proper procedures or you remove a SPA while the software configuration is being applied. After installing a SPA, wait at least 30 seconds before attempting to remove it. After you remove a SPA, wait at least 15 seconds before installing another SPA in the same subslot.

To remove a SPA from a SIP, see Figure 7-2 or Figure 7-4 and follow these steps:


Step 1 If attached, remove any cables from the SPA.

Step 2 To remove the SPA from the SIP, unfasten the captive screws on the SPA, as shown in Figure 7-3 or Figure 7-5.

Step 3 Grasp the handles of the SPA and pull the SPA from the SIP.


 

Online Insertion and Removal

Cisco CRS-1 router SIPs and SPAs support online insertion and removal (OIR). SPAs can be inserted or removed independently from the SIP. Online insertion and removal of a SIP with installed SPAs is also supported.

Optical Device Installation and Maintenance

This section provides references for the installation, removal, and cleaning of optical devices.

Installing and Removing Small Form-Factor Pluggable Modules

For information on installing small form-factor pluggable (SFP) modules, see Gigabit Interface Converter (GBIC) Module and Small Form-Factor Pluggable (SFP) GBIC Module Installation Information and Specifications . The following sections of that document are particularly useful when installing an SFP module:

  • Installing and Removing the GBIC Module or SFP Module”
  • Installing an SFP Module”
  • Installing the GBIC Module or SFP Module Interface Cables”

SPAs accept only supported optical devices. The list of supported optical devices can be found in the “Modular Optics Compatibility” section in the product overview chapter in this guide.

Cleaning Optical Devices

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.

For information on cleaning optical devices, refer to Cisco CRS-1 Carrier Routing System Fiber-Optic Cleaning Guide .

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 LED should be green (on) and the SPA STATUS LEDs should be green (on). The port LEDs 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.

To verify that a SIP and SPA are installed correctly, follow these steps:


Step 1 Observe the console display messages and verify that the system discovers the SIP, while the system reinitializes each interface, as follows:

  • As a SIP is initialized, the LED is first amber, indicating that power is on, but the SIP is being configured. When the SIP is active, the LED illuminates green.
  • SPAs follow the same sequence after the SIP has completed its initialization. The SPA STATUS LEDs illuminate amber, turning to green when the SPAs become active.
  • When the SIP and SPA STATUS LEDs are green, all associated interfaces are configurable.

For configuration instructions, see Cisco IOS XR Interface and Hardware Component Configuration Guide at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/ioxsoft/iox34/cgcr34/index.htm

  • When a SIP or SPA is replaced with a module of the same type (as in an OIR or hardware swap), the previous configuration is reinstated when the SIP or SPA becomes active.
  • When a SIP or SPA has not been previously installed in the same slot or subslot, then the configuration for all associated interfaces is empty.

Note New interfaces are not available until you configure them.


Step 2 If the SIPs and SPAs have not become active within three minutes, see Chapter8, “Troubleshooting the Installation”


 

Using show Commands to Verify SIP and SPA Status

The following procedure uses show commands to verify that the new SPAs are configured and operating correctly.


Step 1 Use the show running-config command to display the system configuration. Verify that the configuration includes the new SPA interfaces.

Step 2 Use the show hw-module subslot brief or show hw-module subslot status command to display all of the current SPAs and a summary of their status.

Step 3 Use the show inventory command to display details about the installed hardware in the system.

Step 4 Use the show hw-module fpd command to verify the FPD version information of the SPAs installed in the system.


Note If a SPA does not meet the minimum FPD version required, it might not function properly. If you receive an error message on the system console that there is an FPD image incompatibility, you should upgrade the FPD image on the SPA.


For more information about FPD upgrades, see the “Upgrading Field-Programmable Devices” chapter in Cisco IOS XR Interface and Hardware Component Configuration Guide at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/ioxsoft/iox34/cgcr34/index.htm

Step 5 Use the show version command to obtain a few details on the installed SIPs and interfaces available.


 

Using show Commands to Display SPA Information

Table 7-1 describes the show commands you can use to display SPA information.

 

Table 7-1 show Commands to Display SPA Information

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.

SPA Cable-Management Brackets

SPAs are shipped with an accessory kit that includes cable-management brackets.

To install or remove cable-management brackets on a SPA, see Figure 7-6 and perform the following steps:


Step 1 Screw the two pull assemblies into both sides of the SPA.

Step 2 Insert the cable-management bracket into the slot.

Step 3 To remove the cable-management bracket, press the button on the bracket and pull it out.


 


Note Blank filler plugs are provided if no cable-management brackets are installed.
