Introduction to m9200-s2ek9-kickstart-mz.5.0.4b.bin
This kickstart image provides the essential boot environment for Cisco MDS 9200 Series Multilayer Fabric Switches, specifically engineered for Supervisor-2 module configurations. As part of the NX-OS 5.x software family, it initializes hardware diagnostics and prepares the switch for subsequent system image loading (e.g., m9200-s2ek9-mz.5.0.4b.bin).
Designed for MDS 9222i/9216i switches with 4-Gbps Fibre Channel capabilities, this release maintains backward compatibility with legacy 2-Gbps FC modules while introducing firmware optimizations for enterprise SAN environments. Though exact release dates aren’t publicly documented, version 5.0(4b) represents a stability-focused update within the NX-OS 5.x train, typically deployed in mid-2010s storage infrastructure.
Key Features and Enhancements
1. Boot Process Optimization
- 25% faster hardware initialization compared to NX-OS 4.3 releases
- Enhanced diagnostic routines for Supervisor-2 module self-checks
2. Security Framework
- Signed image verification to prevent unauthorized firmware modifications
- TACACS+ protocol enhancements for role-based VSAN access control
3. Hardware Support
- Expanded compatibility with 48-port 4-Gbps FC modules (MDS 9222i)
- Support for 18/4-port Multiservice Modules in hybrid FC/IP configurations
4. Protocol Enhancements
- Improved FCIP compression algorithms for WAN optimization
- Stabilized iSCSI session management for IP storage environments
5. Resource Management
- Dynamic buffer allocation for mixed 2/4-Gbps FC port configurations
- Bootflash integrity checks during system initialization
Compatibility Requirements
Supported Hardware
| Model | Supervisor Module | Minimum NX-OS | Port Configuration |
|---|---|---|---|
| MDS 9222i | Supervisor-2 | 4.2(1) | 18 FC + 4 IP service ports |
| MDS 9216i | Supervisor-2 | 4.2(1) | 16 FC ports |
System Requirements
- Bootflash: 150MB available space
- DRAM: 4GB minimum for full feature operation
- Image Pairing: Requires system image m9200-s2ek9-mz.5.0.4b.bin
Known Limitations
- Hardware Restrictions
- Incompatible with Supervisor-3/4 modules or 8-Gbps FC adapters
- Limited to 32 active VSANs vs. 256 in later NX-OS versions
- Upgrade Constraints
- Direct upgrades from NX-OS 3.x require intermediate 4.2(3) installation
- Mandatory disruptive upgrade when moving from 5.0(3) or earlier
- Feature Limitations
- No support for Smart Licensing (manual license activation required)
- FCoE functionality restricted to basic initialization
