Nokia 3HE07390AA XMA Impedance Panel | 7950 XRS XCM Filler

Nokia (Alcatel-Lucent) 3HE07390AA XMA Impedance Panel for 7950 XRS XCM Carrier

3HE07390AA is the Nokia XMA Impedance Panel, an accessory blank filler panel designed for the XCM carrier module on the 7950 XRS routing platform. It is used to cover unused XMA slots inside an XCM, maintaining proper electrical impedance, airflow, EMI shielding and stable operation for the XCM carrier.

Key Features

• Model: XMA Impedance Panel, Part Number: 3HE07390AA (3HE07390AARC01)
• Accessory filler panel for vacant XMA slot within XCM carrier module (3HE06936AA)
• Mandatory filler panel: Must be installed in every empty XMA slot within the XCM carrier to ensure proper system operation and impedance matching.
• Maintains chassis airflow, cooling performance and EMI compliance
• Prevents system errors and unstable operation caused by unmatched impedance
• Simple snap-in installation, matching the form factor of standard XMA cards

Platform Compatibility

Designed exclusively for Nokia 7950 XRS‑20 chassis, for use inside the XCM carrier module. Each XCM holds up to two XMA cards; any empty XMA slot requires this impedance panel to avoid impedance mismatch and system faults.
