Chapter 2. Starting and configuring the M12
You must configure the M12 appropriately in order for it to operate correctly within
the network and fabric.
Note: The switch only detects modems during power on or restart. If you connect a
modem to an operating switch, you must restart the switch for it to detect the
modem.
This chapter describes how to start and configure the M12 and includes the
following information:

Providing initial power to the switch
Perform the following steps to provide ac power to the switch:
1. Connect the cabinet power distribution units (PDUs) to separate power sources
of 200–240 V ac, 50–60 Hz.
2. Make sure that the internal power cords are connected to the separate PDUs
and that the other ends are connected to the M12 circuit breakers.
3. Route the power cord so that it is not exposed to stress.
4. Flip both green ac power switches to “|”. The ac power switches light up green
when switched on, and power is being supplied.
The switch automatically performs a POST by default each time you power on. A
POST takes a minimum of 3 minutes. A POST is complete when light-emitting diode
(LED) activity returns to a standard state. For information about LED light patterns,
see “Interpreting LED activity” on page 20.
Attention: Do not connect the switch to the network until you configure the IP
addresses.
Configuring the M12
The M12 can contain up to two logical switches, each with its own configuration:
v
One logical switch for any 16–port cards in slots 1–4
v
One logical switch for any 16–port cards in slots 7–10
The configuration information for both logical switches is stored in the WWN card
and in the flash memory of the CP cards. The configuration is automatically
mirrored to the standby CP card, so that the most current configuration remains
available even if the active CP card fails. You can back up the configuration to a
workstation by using the configUpload command. You can download the
configuration to the active CP card by using the configDownload command. For
information about commands and whether you can enter them through the active or
standby CP card, see the Brocade Fabric OS Reference .
Note: You should routinely back up the configuration to ensure that the current
configuration is available if needed.
