How to install Cisco WS-X4748-UPOE+E Service Module

Install the WS-X4748-UPOE+E into a Cisco Catalyst 4500E chassis that supports E-Series line cards. Verify chassis compatibility and ensure you have a compatible supervisor engine and power configuration before installation. The module is hot-swappable, but for best practices, coordinate with your network maintenance window to perform changes with minimal impact.

Steps for installation (summary):

1) Power down the affected line or prepare for hot-swappable replacement in a supported chassis configuration, if required by your environment.

2) Identify an available slot in the Catalyst 4500E chassis that supports E-Series line cards and is designated for PoE/UPOE-enabled modules.

3) Align the WS-X4748-UPOE+E module with the slot guide, firmly seating it until it is fully engaged and the carrier rails click into place.

4) Reconnect any console or management interfaces as needed, then power up the chassis or the affected line card. Allow the module to initialize and come online.

5) Verify basic operation with the appropriate Cisco command set (for example, show module or show inventory) and monitor port status and PoE/UPOE activity via the device management interface.

6) Configure network policies, QoS, PoE power budgets, and security settings to align with your deployment requirements. Save the running configuration to ensure changes persist after reboot.

Best practices include validating firmware compatibility, reviewing power budgets to accommodate all connected devices, and performing a controlled test of critical applications to confirm that the new line card meets performance expectations in your environment.
