Switch Module
4-9
Preparatory Steps
Carry out the following preparatory steps.
1
Install main and redundant switch modules in the switch module slot 1
and slot 2 respectively (see “Installing a Switch Module” on page 4-5). Do
not run the Integrated Fast Setup yet.
Each time the switch is rebooted during this procedure the cards change
roles. The main card becomes the redundant card and vice versa. The
main card can always be identified by its ACT LED flashing once every
two seconds. The ACT LED of the redundant card flashes at a lower rate.
2
Verify that at least one interface card of any type is installed in the
CoreBuilder chassis in any interface card slots 3-6. Data is transferred
between switch modules via a communications chip on an interface card.
3
Verify that the Ethernet management ports in both switches are
connected to the NMS station. They can either be connected through a
hub to the NMS station or through an Ethernet interface card in the same
chassis, such as the CoreBuilder 7400 High Density Ethernet/ATM
interface card, to the NMS station.
During the procedure you will need to verify connectivity between the
NMS station and the switch by pinging the switch module from the NMS
station.
Connectivity between the switch module and its attached devices is
established by an RARP transmitted by the switch module when it boots.
The RARP causes a device to learn the MAC address of the switch
module. However, there are certain devices, for example, a Solaris station,
which will not learn a new MAC address for an IP when one already
exists. If you are using one of these devices as an NMS station, and you
are unable to ping the switch module, try erasing the switch module’s
MAC address from the device’s ARP table and ping again.
4
Verify that the RS-232 terminal line is connected to the console port on
the main switch module.
Procedure Execution
1
Reset the configuration of both switch modules by executing the
RESETCFG.BAT file supplied with your software.
Do not use the LMA menu (1) SYS / (2) RES to reset the switch module
configuration.
