Installing and Removing a SPA

This chapter describes how to install or remove SPAs on the Cisco 7600 series router. This chapter contains the following sections:

Handling SPAs

Each SPA circuit board is mounted to a metal carrier and is sensitive to electrostatic discharge (ESD) damage. See the “Preventing Electrostatic Discharge Damage” section for ESD precautions.

Before you begin installation, read Chapter 1, “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 1-1.)

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 SPAs. If you plan to install a SPA in a subslot that is not in use, you must first remove the SPA blank filler plate.

SPA Installation and Removal

This section provides step-by-step instructions for installing and removing a SPA in a SIP.


Caution When performing the following procedures, wear a grounding wrist strap to avoid ESD damage to the SPA. Some platforms have an ESD connector for attaching the wrist strap. Do not directly touch the midplane or backplane with your hand or any metal tool.

See Preventing Electrostatic Discharge Damage for information about ESD.

Installing a SPA in a SIP

To install a SPA in a SIP, do the following:


Step 1 To insert the SPA in the SIP, 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.

Step 2 Carefully slide the SPA all the way in 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 installation screws on either side of the SPA.


 

Removing a SPA from a SIP

Before you remove a SPA from the SIP, read this important information about SPA cable clips that will help to make removing the SPA easier. The SPA accessory kit is shipped with three different versions of cable clips, as shown in Figure 1-3.

Follow the procedure to install one set of the shipped cable clips to the already installed plastic pull tab on the SPA. Figure 1-2 shows the SPA with the plastic pull tab installed.

Step 4 You have installed the cable clip to the SPA. Go to the next step to remove the SPA.

Step 5 If attached, remove any cables from the SPA.

Step 6 To remove the SPA from the SIP, unfasten the captive installation screws on either side of the SPA. Figure 1-6 illustrates how to remove a SPA in a SIP.

This completes the procedure for removing a SPA from the SIP.

Online Insertion and Removal

Cisco 7600 series router SIPs and SPAs support online insertion and removal (OIR). SPAs can be inserted or removed independently from the SIP. OIR of a SIP with installed SPAs is also supported.

For more information about performing OIR, refer to the “Preparing for Online Removal of a SIP” section.

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 the Inspection and Cleaning Procedures for Fiber-Optic Connections and the Compressed Air Cleaning Issues for Fiber-Optic Connections documents 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 STATUS LED should be green (on) and the SPA STATUS LEDs should be 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 reinitialization.

Use the following procedure to verify that a SIP and SPA are installed correctly:


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

  • When a new SPA is inserted into the system, the default configuration will be used for the associated interfaces.
  • As a SIP is initialized, the STATUS LED will first be amber, indicating that power is on, but the SIP is being configured. When the SIP is active, the STATUS LED will illuminate green.
  • SPAs will follow the same sequence once the SIP has completed its initialization. The SPA STATUS LEDs will illuminate amber, turning to green when the SPAs become active.
  • When the SIP and SPA STATUS LEDs are green, all associated interfaces are configurable.

Note Refer to the Cisco 7600 Series Router SIP, SSC, and SPA Software Configuration Guide for configuration instructions.


  • If a SIP or SPA is replaced with a module of the same type (as in an OIR or hardware swap), the previous configuration will be reinstated when the SIP or SPA becomes active.
  • If a SIP or SPA has not been previously installed in the same slot or subslot, then the configuration for all associated interfaces will be 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, refer to the system console messages as follows:

  • If a SIP or SPA is undergoing a field-programmable device (FPD) upgrade, then console messages will indicate that the FPD process has been initiated. The upgrade process might take several minutes. Use the show upgrade fpd progress command to obtain information about the FPD process. SIPs or SPAs that undergo an FPD upgrade will automatically be rebooted. Return to Step 1.
  • If there is no indication that an FPD upgrade is under way, see Chapter1, “Troubleshooting the Installation”


 

Using show Commands to Verify the 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 Display all of the current SPAs and a summary of their status using the show hw-module subslot all oir command.

Step 3 Display information about the installed SIPs using the show diag command.

Step 4 Use the show hw-module subslot all 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 will be updated automatically. If the update fails, the failing SPA will be powered down and an error message will be reported on the system console.


For more information about FPD upgrades, refer to the “Upgrading Field-Programmable Devices” chapter of the Cisco 7600 Series Router SIP, SSC, and SPA Software Configuration Guide .

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


 

Using show Commands to Display SPA Information

Table 1-1 describes the show commands you can use 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. Figure 1-7 shows cable management brackets installed in a SPA, as well as cable routing.

Figure 1-7 SPA Cable Management Brackets

 

To install cable management brackets on a SPA, 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, depress the button on the bracket and pull it out.
