Alcatel-Lucent 3HE10311AA IOM-e Base board

Description

Product Introduction & Engineering Value

The Alcatel-Lucent 3HE10311AA is a 7750 SR-e IOM-e baseboard used within Nokia’s service-router architecture. It is not simply a generic network interface card; the exact part number matters because the 7750 SR-e platform has closely related IOM-e variants with different software capabilities.

For replacement work, verify the chassis, installed CPM, software release, and existing IOM configuration before ordering. Public equipment records also identify 3HE10311AA specifically as a 7750 SR IOM-e router module.

Technical Specifications

A particularly important procurement detail: 3HE10311AA, 3HE10311BA, and 3HE10311CA should not be treated as automatically interchangeable solely because their baseboard descriptions are similar. Nokia’s published product listing associates different software functionality with the three versions.

Field Application & the “Trench” Experience

A plausible replacement scenario looks like this: a service-provider maintenance team has a 7750 SR-e chassis showing an IOM-related hardware fault during a maintenance window. The spare-room inventory contains a board labeled only by the shortened family description, so the engineer checks the equipment BOM and finds 3HE10311AA. Before installation, the team compares the complete part number against the failed board and confirms the chassis/software combination.

That check prevents a surprisingly common mistake: ordering an apparently equivalent IOM-e variant without confirming its licensed functionality.

Niche application scenarios include:

• Mobile backhaul aggregation where 7750 SR equipment handles high-volume aggregation traffic.
• Metro Ethernet service aggregation within a carrier routing node.
• Service-provider edge routing where an existing 7750 SR-e installation needs a like-for-like hardware replacement rather than a platform migration.

A current trade listing also identifies 3HE10311AA as a 7750 SR-e IOM-e product, while another equipment source describes it as a router-equipment base plate.

Transparency SOP: QA & Testing

For New Surplus inventory, the key issue is authenticity and traceability rather than simply cosmetic condition.

A practical receiving/QA procedure should include:

1. Part-number verification — confirm the complete 3HE10311AA marking and compare labels against the purchase documentation.
2. Visual inspection — examine PCB surfaces, connectors, mounting points, labels, and storage damage.
3. ESD-safe handling — keep the board in appropriate antistatic packaging until installation.
4. Functional verification where test equipment is available — install into a compatible 7750 SR-e test environment and verify hardware recognition and operational status.
5. Configuration check — confirm that the replacement corresponds to the required IOM-e software/license configuration.
6. Documentation — retain serial-number and condition records for the spare-parts inventory.

One public supplier currently lists 3HE10311AA as a refurbished IOM-e baseboard, while another marketplace lists a new OEM-component option. Those listings demonstrate that condition terminology varies by supplier, so procurement documentation should explicitly state New Surplus, New OEM, or Refurbished rather than accepting “new” as sufficient.

The Veteran’s Tech Trap Guide

⚠️ Trap #1 — Confusing AA, BA, and CA

This is the first thing I would check. The three numbers look almost identical, but Nokia’s published listing assigns different software functionality to them. Do not substitute one based on physical similarity alone.

⚠️ Trap #2 — Ignoring the software environment

A hardware replacement can be physically correct and still create an integration problem if the installed software/license configuration does not support the required functionality.

PRO TIP: Capture the failed unit’s exact part number, chassis type, software release, and relevant configuration before placing the purchase order.

⚠️ Trap #3 — Treating a baseboard as a generic line card

The 3HE10311AA is identified as an IOM-e Baseboard, not a generic Ethernet interface card. Procurement teams should use the complete equipment BOM and module architecture when determining the replacement.

Dynamic FAQ

Q1. What is the Alcatel-Lucent 3HE10311AA?
It is a 7750 SR-e IOM-e Baseboard used in Nokia/Alcatel-Lucent service-router equipment.

Q2. Is 3HE10311AA the same as 3HE10311BA or 3HE10311CA?
No. They are related IOM-e baseboard variants, but Nokia’s product documentation associates them with different software functionality. Verify the exact required variant before substitution.

Q3. Is 3HE10311AA still found in deployed equipment?
Yes. A 2024 equipment approval listing specifically identifies the Nokia 7750 SR IOM-e using 3HE10311AA, and current commercial listings continue to identify the part.

Q4. What should I provide when requesting a replacement?
Provide the complete part number 3HE10311AA, equipment/chassis model, module position if known, software release, required condition, and whether you require New OEM, New Surplus, or Refurbished stock.

Q5. How can I verify New Surplus authenticity?
Request clear photographs of the original manufacturer labels, complete part-number markings, serial information where applicable, packaging evidence, and a written statement of condition. “New” should not be accepted as a substitute for a defined condition specification.

Q6. What warranty should I expect?
Warranty terms depend on the supplier and stock condition. For a critical telecom spare, obtain the warranty period and coverage in writing before purchase, including whether DOA testing, return shipping, and replacement are covered.
