4To seat the module, firmly push the module forward to engage the module and backplane connectors. You will feel a slight resistance as the connectors engage.
CAUTION: If the resistance is too great, the module and backplane connec- tors may not be aligned. Forcing the module forward could damage the board or backplane connectors. If necessary, remove and reinsert the module, ensuring that the connectors are properly aligned. You should not have to seat the module by tightening the captive screws.
5Tighten the captive screws to secure the module in the chassis.
Once the module is installed, see Chapter 4: Cabling the System in your Getting Started guide for information on cabling the module to the network.
Option Module Module diagnostics run at power up or when replacing a module with the Diagnostics power on. During diagnostics, the module’s port status Error LEDs are lit
yellow. When diagnostics are successfully completed, the port status Active LEDs turn green for those ports that are cabled. If any port status Error LEDs remain yellow, the port is not operational. If the module’s Board Error LED is lit yellow, the module has failed a diagnostic test. To troubleshoot module failures see Chapter 7: Troubleshooting the System in your Getting Started guide.
