How to install Cisco Expansion Module

Follow these general steps to install the Cisco Expansion Module in a compatible Cisco system. Ensure you observe standard safety and electrostatic discharge (ESD) precautions and consult your device’s official service guide for model-specific instructions.

• Power down the host device and unplug it from the power source. Disconnect any connected peripherals as required to prevent damage during handling.
• Open the chassis or device casing according to the manufacturer’s service guide and locate the designated expansion slot. Verify that the slot is free of debris and that the slot latch or retention mechanism is ready for use.
• Align the expansion module with the slot, ensuring correct orientation and alignment with connector pins. Firmly seat the module into the slot until it sits flush and engages with the midplane or connector interface.
• Secure the module with any retention screws or locking mechanisms specified for your chassis. Recheck alignment to ensure there are no gaps and that the module remains firmly seated after tightening.
• Reassemble the enclosure, reconnect power, and boot the device. Log into the device management console to confirm that the new module is detected, then proceed with baseline configuration, firmware updates if needed, and a functional test to verify connectivity and performance.
