4. Product Introduction
The Extreme Networks BDX-MM1 is the Management Module for the BlackDiamond X8 chassis. It handles control plane functions, system management, and runs ExtremeXOS for the entire modular switch.
Deploy two modules for 1+1 redundancy to ensure continuous operation during failures or maintenance. It is essential for powering up and managing the high-density 40GbE and other I/O modules in the X8 platform.

5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| Chassis not booting | Single MM failure or both failed | High | Check MM LEDs and show slot on active module | Reseat or replace with redundant MM |
| Failover not occurring | Redundancy not configured | Medium | Verify show mm or redundancy status | Configure and test failover |
| Management access lost | Console/Ethernet issue | High | Test direct console connection | Check cabling and baud rate (usually 9600) |
| High CPU or slow response | Software process or memory issue | Medium | Run show process and show memory | Check logs; consider software upgrade |
| MM health check failure | Hardware fault or backplane connection | High | Review system logs for MM errors | Reseat module firmly in slot |
If basic reseating does not resolve the issue, capture diagnostic logs from the active MM and contact support.
6. Frequently Asked Questions (FAQ)
How many BDX-MM1 modules are needed? Two modules are required for standard 1+1 redundancy. A single module will operate the chassis but without automatic failover protection.
Is the BDX-MM1 hot-swappable? Yes, with a redundant pair installed. You can replace one while the other remains active, but follow the documented procedure to avoid control plane disruption.
Does this module include any ports? It provides console and out-of-band Ethernet management ports. Data traffic is handled by the I/O modules and fabric.
Is this module still supported? The BlackDiamond X8 platform is end-of-sale. New surplus units are available, fully tested in an X8 chassis, and backed by a 1-year warranty.
What software version does it support? It runs ExtremeXOS versions compatible with the X8 chassis (typically 15.x and 16.x). Confirm exact compatibility with your I/O and fabric modules.
How do I perform a manual switchover? Use the appropriate ExtremeXOS command for MM failover. Test this during a planned window to verify redundancy works as expected.
Can I mix revisions of the BDX-MM1? Match revisions where possible for best compatibility. Our stock is verified for consistent operation in redundant pairs.
