Troubleshooting guide

server will then serve this static IP address to the monitoring line card

when it boots and asks for it. On Linux, this file is /etc/dhcpd.conf.

The MAC address is a group of 6 hexadecimal numbers separated by

colons, and should begin with 00:60:dd:??:??:??.

Step 2. Before seating the monitoring line card into the top slot of the

Myrinet-2000 switch, connect at least the first ethernet port to the LAN.

For high availability, the second ethernet port can also be connected.

The monitoring line card can ONLY be installed in the top slot of your

Myrinet-2000 switch.

The ethernet ports on the monitoring line card are 10base-T.

Step 3. When the monitoring line card is locked in position, a green LED

for the line card and the LEDs for the connected ethernet port(s) will

illuminate. The monitoring line card will immediately start to broadcast

DHCP requests. When the monitoring line card has received its IP

address, it is reachable. You can ping the card or open a web browser to it.

To determine the IP address that was assigned to the monitoring line card,

look at the file /var/state/dhcp/dhcpd.leases on your DHCP server.

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. The lease time is 1 day.

To test that your monitoring line card is properly installed, 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 description of these

features can be found in the “Myrinet-2000 Switch Information” section of the

Myrinet FAQ (http://www.myri.com/scs/FAQ/).

If you have difficulties installing the monitoring line card, refer to the Myrinet

FAQ entry “How do I install the monitoring line card in my Myrinet-2000 M3-E*

switch?” (http://www.myri.com/cgi-bin/fom?file=200) and feel free to contact
