Sometimes when a Blade's MM goes down and you cannot access the web interface of the MM your last resort is the SSH and/or Telnet interface.
This document explains how to reset the Management Module (MM) interface of a Blade chassis through it's Telnet command-line interface.

In order to reset the MM from a Telnet session when, first telnet to the target's MM, e.g.:
$ telnet blademm.example.org Trying 10.xxx.yyy.zzz... Connected to blademm.example.org. Escape character is '^]'. username: admin password: Hostname: blademm Static IP address: 10.xxx.yyy.zzz Burned-in MAC address: 5C:F3:00:01:02:03 DHCP: Disabled - Use static IP configuration. Last login: Thursday August 9 2012 10:13 from 10.xxx.yyy.zzz (Web)

system> env -T system:mm OK
