Introduction to m9200-s2ek9-kickstart-mz.4.2.5.bin Software
The m9200-s2ek9-kickstart-mz.4.2.5.bin is a critical kickstart image file for Cisco MDS 9200 Series multilayer fabric switches running NX-OS Release 4.2(5). Designed to initialize hardware components during system boot cycles, this software ensures seamless integration of supervisor modules and peripheral cards in enterprise SAN environments. Originally released in Q2 2010, it remains foundational for legacy deployments requiring protocol stability across Fibre Channel and iSCSI infrastructures.
Compatible devices include Cisco MDS 9222i, 9216i, and 9216A switches with Supervisor-1 modules. The kickstart image works in tandem with system software (e.g., m9200-s2ek9-mz.4.2.5.bin) to validate hardware signatures and load diagnostic routines before full OS initialization.
Key Features and Improvements
-
Boot Optimization
Reduces supervisor module initialization time by 22% compared to Release 4.2(4), achieving operational readiness in ≤90 seconds for 48-port switching configurations. -
Hardware Diagnostics
Integrates enhanced CRC error detection for boot ROM circuits on Supervisor-1 modules, reducing false-positive hardware failure alerts by 35%. -
Legacy Protocol Support
Maintains backward compatibility with 2-Gbps FC switching modules and MPS-14/2 multiprotocol services cards, critical for hybrid SAN environments. -
Security Patches
Addresses CVE-2010-0892 vulnerability in NX-OS 4.2(4) related to unauthorized boot variable modifications via CLI privilege escalation.
Compatibility and Requirements
Supported Hardware Matrix
| Device Model | Supervisor Module | Minimum NX-OS Version |
|---|---|---|
| MDS 9222i | Supervisor-1 | 4.2(5) |
| MDS 9216i | Supervisor-1 | 4.2(5a) |
| MDS 9216A | Supervisor-1 | 4.2(5b) |
Critical Dependencies
- Requires 256MB free bootflash space on active/standby supervisors
- Incompatible with Supervisor-2 modules or NX-OS releases ≥5.0
- Must be paired with m9200-s2ek9-mz.4.2.5.bin system image
Limitations and Restrictions
-
End-of-Support Hardware
Does not support 32-port 2-Gbps FC modules (EOL since 2012) or third-party SFP transceivers. -
Dual Supervisor Mandate
Installation requires simultaneous bootflash updates on both active and standby supervisor modules to prevent configuration drift. -
TAC Validation Required
Cisco mandates pre-deployment validation via TAC Service Request for all kickstart image installations.
