5.1.1 Rebooting the monitoring line card

The easiest way to reboot a Myrinet interconnect is with a Web browser. In the

following steps, uc denotes microcontroller:

1.

Get the main page (http://

switchname

).

2.

Click on the link "Slot 56 (big uc)."

3.

Select "reboot" from the menu "commandForBigUc."

4.

Click on Apply.

This does not reset all the counters in other line cards. To do this, you have to also

reboot each line card microcontroller, as follows:

1.

Get the main page (http://

switchname

).

2.

Click on the link "Slot 1."

3.

Click on the link "reboot.”

4.

Check the checkbox "reboot."

5.

Check the radio button "all Ucs."

6.

Click on Apply.

Usually customers just want to reboot a Myrinnet interconnect after

reprogramming the firmware, or to change its IP address, in which case it is

enough to just reboot the monitoring card.

5.2 Removing and installing an 8-port line card

Each 8-port line card has a pair of handles that lock the card in place and serve

as a lever for inserting or removing the line card. The handles snap toward the

middle when installed.

To remove an 8-port line card or the monitoring line card, use the following

procedure:

1.

Press the red tabs to unlock the handles (Figure 5-1).

Figure 5-1: Unlocking Switch Card Handles

2.

Turn both handles outward together. You should be able to see and feel

the lever action as the front panel of the line card is ejected toward you

(Figure 5-2).
