Product Introduction & Supply Chain Strategy
The Alcatel-Lucent 3HE09881AA is a high-density 10-port 10GbE MDA-e designed for the 7750 Service Router platform. This module provides carrier-grade Ethernet density, enabling service providers and large enterprises to scale edge routing capacity without requiring a full chassis upgrade. It integrates seamlessly into IOM4-e carrier cards to deliver low-latency, wire-speed performance for demanding IP/MPLS applications.
From a procurement perspective, sourcing this module as New Surplus offers a strategic advantage by reducing the Total Cost of Ownership (TCO) while maintaining OEM-level reliability. Unlike refurbished units that may harbor hidden thermal fatigue or degraded optics-seating, these New Surplus units ensure 100% duty cycle stability. This is an essential “insurance policy” stock item for data centers to mitigate the risk of high-cost emergency downtime.

Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
- Verify Compatibility: Ensure the host IOM (Input/Output Module) supports MDA-e cards.
- Safety Gear: Put on a grounded ESD wrist strap before handling the module.
- Documentation: Record the serial numbers and current firmware of existing modules in the 7750 SR chassis.
Stage 2: Removal
- Fiber Management: Disconnect all SFP+ transceivers and protect fiber tips with dust caps.
- Unlocking: Loosen the captive screws on the existing MDA or blanking plate.
- Extraction: Use the ejector levers to break the backplane seal, pulling the unit straight out to avoid damaging the alignment pins.
Stage 3: Installation (Clone & Seat)
- Alignment: Slide the 3HE09881AA into the IOM slot using the guide rails.
- Seating: Firmly press the ejector levers inward simultaneously to seat the high-density connectors into the IOM.
- Securing: Hand-tighten the captive screws to ensure a solid electrical ground.
Stage 4: Power-On & Testing
- LED Status: Observe the “STAT” LED; a solid green light indicates the module has passed its Power-On Self-Test (POST).
- CLI Verification: Use the command
show mdato confirm the system recognizes the hardware. - Provisioning: Configure the ports using the
config>card>mdacontext in the TiMOS/SR-OS CLI.
Firmware/Software Versions & Upgrade Notes
The 3HE09881AA requires a minimum SR-OS (TiMOS) version 12.0.R1 or higher to operate correctly. We recommend running the latest Long Term Support (LTS) release to ensure all 10GbE framing features and diagnostic capabilities are active.
Critical Risk Note: Swapping hardware between chassis running significantly different SR-OS versions can lead to “Boot-Env” mismatches. Always verify that the FPGA version on the new MDA is compatible with your current supervisor firmware before committing to a live traffic cutover.
Frequently Asked Questions (FAQ)
- Is this unit truly “New”?
Yes. This is New Surplus inventory, meaning it has never been deployed in a production environment. It arrives in original packaging (opened only for our mandatory QC inspection) and is free from the wear-and-tear found in “refurbished” or “pulled” hardware.
- Why is the price lower than my local Nokia representative?
We leverage global supply chain shifts. When large carriers over-provision for projects that get canceled, we secure that excess inventory. You receive the exact same OEM hardware without the massive corporate markup.
- Can I hot-swap this MDA while the router is running?
The 7750 SR platform supports the hot-swapping of MDAs. However, ensure that the corresponding ports are administratively shut down in the software before physical removal to prevent data corruption or line-card instability.
- Does it come with SFP+ transceivers?
No, the 3HE09881AA is the base interface card. SFP+ optics (SR, LR, or ER) must be purchased separately based on your specific distance requirements.
- What is the warranty on a New Surplus module?
We provide a comprehensive 1-year replacement warranty. Because these are new units, the failure rate is near zero, but our warranty ensures you are protected against any manufacturing defects.
