Optical Device Installation and Removal (SPA-2GE-7304

optional procedure)

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 table in the product overview chapter of 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 Inspection and Cleaning Procedures for

Fiber-Optic Connections.

Checking the Installation

This section describes the procedures you can use to verify the MSC and SPA installation, and includes

information on the following topics:

• Verifying the Installation, page 6-4

• Using show Commands to Verify MSC and SPA Status, page 6-6

• Using show Commands to Display SPA Information, page 6-7

• Using the ping Command to Verify Network Connectivity, page 6-8

Verifying the Installation

This section describes how to verify the MSC and SPA installation by observing the MSC LED states,

SPA LED states, and the information displayed on the console terminal.

When the system has reinitialized all interfaces, the MSC STATUS LED should be green (on) and the

port LEDs on the SPAs should 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.
