Switch Module 4-9

Preparatory Steps

Carry out the following preparatory steps.

1Install 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.

2Verify 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.

3Verify 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.

4Verify that the RS-232 terminal line is connected to the console port on the main switch module.

Procedure Execution

1Reset 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.
