Redback Networks 600-0112 REV 01-CE2-VAC1AA0AAA SMS1000 Retrofit Module

Redback Networks 600-0112 REV 01-CE2-VAC1AA0AAA SMS1000 Retrofit Module: Legacy-Compatible Upgrade for SMS1000 Series Systems

The Redback Networks 600-0112 REV 01-CE2-VAC1AA0AAA is a subscriber management and edge routing module designed for the SMS1000 platform — a carrier-grade system widely deployed in broadband access networks, DSL aggregation environments, and multi-service edge architectures. As the SMS1000 series reaches end-of-life and original spare parts become increasingly scarce, this module serves as a critical retrofit-compatible replacement for maintenance engineers and network operations teams managing legacy infrastructure.

With original Redback Networks hardware now discontinued and Ericsson successor platforms requiring significant re-engineering, many operators continue to rely on SMS1000 chassis for stable, proven subscriber session management. The 600-0112 REV 01-CE2-VAC1AA0AAA addresses this gap directly — providing a verified, tested replacement that preserves existing rack configurations, backplane connections, and software compatibility without forcing a full platform migration.

NINERMAS maintains in-stock inventory of this module with a 12-month warranty, pre-shipment functional testing, and direct technical support for retrofit planning. Each unit is inspected against original Redback Networks hardware specifications before dispatch.

Retrofit Planning for Existing Automation Systems

Replacing the 600-0112 REV 01-CE2-VAC1AA0AAA within an operational SMS1000 chassis requires careful pre-migration planning to avoid service disruption. Engineers should begin by auditing the existing chassis configuration, confirming the slot assignment of the failed or aging module, and verifying that the replacement unit’s hardware revision (REV 01) is compatible with the installed SMS OS software version running on the SMS1000 Route Processor.

Power capacity is a primary concern. The VAC1AA0AAA suffix indicates an AC power input variant — maintenance teams must confirm that the chassis power shelf, typically a Redback Networks SMS1000 Power Entry Module, is supplying the correct voltage and current capacity for this card. Mismatched power configurations are a leading cause of post-replacement instability in legacy SMS deployments.

Backplane slot addressing must be verified before insertion. The SMS1000 chassis uses a fixed slot-to-address mapping, and the replacement module must be seated in the same physical slot as the original to preserve subscriber session continuity and avoid re-addressing the Subscriber Management Engine configuration. If the chassis also houses a Redback Networks SMS1000 Timing and Synchronization Module, clock source priority should be reviewed to prevent timing disruption during the swap.

For sites running PPPoE subscriber aggregation, the Line Card modules installed in adjacent slots — such as the Redback Networks SMS1000 OC-3 ATM Line Card or DS3 Line Card — must remain undisturbed during the replacement. Their subscriber session tables are managed by the central Route Processor, and any unplanned reset of adjacent cards can cause mass session drops across the aggregation domain.

Communication link continuity is equally critical. If the SMS1000 is integrated into an MPLS backbone via a Redback Networks SMS1000 Gigabit Ethernet Uplink Module, the uplink interface configuration — including VLAN tagging, QoS policies, and routing adjacencies — should be exported and backed up before the replacement procedure begins. This ensures rapid restoration if the new module requires a software re-push.

Sites that have integrated the SMS1000 with an external NMS or OSS platform via SNMP or CORBA interfaces should also verify that the management IP and community strings remain consistent post-replacement. In environments where a Redback Networks SmartEdge 800 or SmartEdge 1200 is being used as a migration target, the 600-0112 REV 01-CE2-VAC1AA0AAA can extend the operational life of the SMS1000 platform while the parallel migration is staged — reducing the pressure to execute a hard cutover under time constraints.

For installations where the SMS1000 chassis is co-located with legacy DSLAM equipment and a Redback Networks SMS1000 ATM Uplink Module handles the aggregation path, the replacement module must be validated against the ATM PVC configuration to ensure that subscriber VCs are correctly mapped after the card comes online. A Redback Networks SMS1000 Management Module or equivalent craft terminal connection is recommended for local console access during commissioning.

Downtime Control During System Migration

Minimizing downtime during a 600-0112 REV 01-CE2-VAC1AA0AAA replacement requires a structured, pre-tested procedure. The recommended approach is to perform the swap during a scheduled maintenance window, with all subscriber session data exported from the SMS1000 Route Processor in advance. If the platform supports stateful switchover (SSO) or non-stop routing (NSR) via a redundant Route Processor, these features should be activated before the physical replacement to maintain forwarding continuity.

Original program logic — including subscriber policies, QoS profiles, AAA server configurations, and routing tables — should be saved to an external configuration management system before the module is removed. This protects against configuration loss in the event that the replacement module initializes with factory defaults or requires a full software load.

Field engineers should prepare a rollback plan: retain the original module in a testable state until the replacement has been confirmed stable under live traffic for a minimum of 24 hours. This is particularly important in environments where the SMS1000 is the sole subscriber management point for a large DSL aggregation node, where a failed replacement could affect thousands of active sessions simultaneously.

NINERMAS provides pre-shipment functional testing on all 600-0112 REV 01-CE2-VAC1AA0AAA units, reducing the risk of DOA hardware on-site. Each module is shipped with a test report confirming power-on, slot recognition, and basic interface initialization. Combined with the 12-month warranty, this gives operations teams confidence that the replacement hardware will perform reliably from day one of deployment.

Retrofit Support FAQ

Q1: Is the 600-0112 REV 01-CE2-VAC1AA0AAA a direct drop-in replacement for the original SMS1000 module?
Yes. This module is designed for direct slot-compatible installation in the SMS1000 chassis. No chassis modification is required. Verify that the hardware revision and software version are aligned with your installed SMS OS before insertion.

Q2: What pre-installation checks are required for wiring and terminal connections?
Confirm AC power input compatibility at the chassis power shelf, verify backplane connector integrity, and inspect the slot for physical damage before seating the replacement module. Terminal block connections on adjacent I/O or line card modules should not be disturbed during the swap.

Q3: How is compatibility with existing SMS1000 software and HMI configurations verified?
Request the current SMS OS version from your network operations team and cross-reference with the hardware revision matrix for the 600-0112. HMI screen configurations and NMS alarm mappings should be validated post-replacement using a local console session via the SMS1000 Management Module or craft port.

Q4: What does the 12-month warranty cover, and what is the stock availability?
The 12-month warranty covers hardware defects and functional failures under normal operating conditions from the date of shipment. NINERMAS maintains in-stock inventory of the 600-0112 REV 01-CE2-VAC1AA0AAA and can confirm lead times upon inquiry. Pre-shipment functional testing is included with every unit.
