Troubleshooting guide
Each time a monitoring line card is powered on, it will ask for its IP 
address (and netmask) via DHCP. You can specify a gateway with the 
DHCP "routers" option. 
To test that the monitoring line card is properly configured, you can ping its IP 
address or open a web browser to its IP address. We suggest that you familiarize 
yourself with the features of the HTTP interface to the monitoring line card, as 
many of these features can be very useful diagnostic tools. A web interface 
tutorial can be found at 
http://www.myri.com/scs/14U_switches/. 
If you have difficulties configuring the monitoring line card, refer to the Myrinet 
FAQ entry “How do I configure the monitoring line card in my M3-CLOS-ENCL-
* and/or M3-SPINE-ENCL-* switch?” (

IV. What Software Do I Need To Install? 
Myricom supplies and supports Myrinet software (low-level firmware and middleware) 
for a variety of operating systems and processors. All Myricom-supported software 
requires a login/password for download. The login/password must be obtained from 
Myricom Technical Support, help@myri.com, via the webpage 
http://www.myri.com/scs/loginrequest.html. 
There are two choices for low-level firmware: MX or GM. For middleware, the 
following APIs are available: MPI, VIA, PVM, Sockets (SDP), and DAPL. 
Performance graphs for Myricom-supported software are available:

The first Myrinet software package you must install is the low-level firmware: MX or 
GM. The low-level firmware includes a driver, Myrinet-NIC control program, a network 
mapping program, and the API, library, and header files. 
•  MX-2G is supported on Myrinet-2000 PCIX-based NICs. 
•  GM-2 is supported on Myrinet-2000 PCIX-based and PCI64-based NICs. 
•  GM-1 is supported on Myrinet-2000 PCI64-based and PCI32-based NICs. 
MX is the next generation of Myrinet software and firmware following GM-2. 
Myricom's Myrinet software support has always spanned two generations of Myrinet 
NICs. GM-2 was released in May 2003 together with the first of the PCI-X series of 
Myrinet NICs, but GM-2 was already backported to operate also with the previous PCI64 
series NICs. MX-10G is supported on Myri-10G NICs, and MX-2G is supported on the 
PCI-X series of Myrinet NICs. MX-2G and MX-10G are fully compatible at the API and 
application levels.
