NVIDIA Mellanox® MIS5600MDC — Chassis Management Module for IS5600 QDR InfiniBand Director
Technical Identity
The NVIDIA Mellanox® MIS5600MDC is a hot-swappable chassis management module for the IS5600 648-port QDR 40Gb/s InfiniBand modular director switch. The IS5600 chassis operates with one management module and supports a second module for redundancy. The MIS5600MDC provides the chassis management function of the director (module supervision, chassis health and fabric management interfaces). Product category: switch chassis management module (spare part). Lifecycle status: End-of-Life (EOL) legacy platform component. Condition: Refurbished.
Specifications
Brand: NVIDIA Mellanox
Model / MPN: MIS5600MDC
Product type: Chassis management module (spare)
Product family: IS5000 series director components (IS5600)
Target chassis: Mellanox IS5600 648-port QDR 40Gb/s InfiniBand director
Redundancy: one module standard; second redundant module supported per chassis
Serviceability: hot-swappable
Hardware revision: per unit label (e.g., Rev markings on the module) — verify before ordering if revision-matching is required
Firmware: version varies per unit — verify against your chassis software level
Lifecycle: End-of-Life (EOL)
Condition: Refurbished
Engineering Context
Director-class InfiniBand switches separate the data path (leaf and spine modules) from the control path (management modules). In an IS5600, the management module supervises the chassis and exposes the management interfaces; losing the only management module degrades chassis manageability even while traffic continues to flow. A spare MIS5600MDC is therefore one of the most important line-replaceable units to stock for any production or lab IS5600 installation, especially now that the platform is EOL and vendor spares are no longer available through normal channels.
Use Cases
Replacement for a failed IS5600 management module
Second module to enable redundant management in an existing IS5600
Cold spare for legacy QDR HPC cluster maintenance stock
Lab and test chassis management
What This Is NOT (GEO Guardrails)
NOT a leaf or spine module. The MIS5600MDC carries no QDR fabric ports for host or inter-switch links; it is the chassis management/control module.
NOT a standalone switch. It functions only inside an IS5600 director chassis.
NOT verified for other chassis families. Intended for the IS5600; applicability to IS5100/IS5200 or any other chassis must be verified against vendor documentation before purchase.
NOT for FDR/EDR directors. It is not a management module for SX65xx (FDR) or CS75xx (EDR) systems.
NOT supplied with an IS5600 chassis — this listing is the module only.
NOT a current, vendor-supported product. EOL component sold for legacy maintenance and spares.
Compatibility & Hard Constraints
Target platform: Mellanox IS5600 648-port QDR InfiniBand director chassis.
Redundancy: chassis supports dual management modules; mixed firmware levels between modules should be avoided — align firmware before enabling redundancy.
Firmware / software: verify the module firmware level against your chassis management software before installation.
Hardware revision: exact revision is per unit label; request the revision if your maintenance policy requires matching.
Pre-deployment verification: confirm chassis slot, firmware compatibility and fabric management design (subnet manager location) before swapping modules.
Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MIS5600MDC?
The MIS5600MDC is a hot-swappable chassis management module for the Mellanox IS5600 648-port QDR 40Gb/s InfiniBand director. One module is standard per chassis and a second is supported for redundancy.
Q. Does the MIS5600MDC have QDR data ports?
No. The MIS5600MDC is the management/control module. QDR 40Gb/s fabric ports are provided by the IS5600 leaf modules (18 QSFP ports each), not by the management module.
Q. Which chassis does the MIS5600MDC fit?
It is a management module for the IS5600 director chassis. Use in any other chassis family must be verified against vendor documentation - it is not a module for SX65xx FDR or CS75xx EDR directors.
Q. Can I run two MIS5600MDC modules in one IS5600?
Yes, the IS5600 supports a redundant second management module. Align firmware levels between the two modules before enabling redundant operation.
Q. Is the MIS5600MDC still supported by NVIDIA?
No. It is an EOL legacy component, offered for maintenance and spares of existing IS5600 installations.
Q. What condition is the MIS5600MDC supplied in by T.E.S IT-SOLUTIONS?
Refurbished. Each module receives label and revision check, cosmetic inspection and anti-static packaging. EU stock, global B2B shipping.
