Installing the SmartSwitch 9000 Module
2-4
Using DIP Switch 6
The purpose of DIP switch 6 is to force a Flash download from a BootP server
through the EM-EPIM. The Þrst step in this process is to conÞgure the BootP
server. ConÞgurations of BootP servers can differ from platform to platform and
from one operating system to another. Read the userÕs manual on BootP and
TFTP serving for the correct Þles to edit and the correct Þles to execute for the
server. After conÞguration of the BootP server the module can then have the
switch state changed on dip switch 6 to initiate BootP and TFTP requests.
When the state of dip switch 6 is changed, the module begins requesting a BootP
server in an attempt to receive a Flash image download. The modules boot PROM
initiates a BootP sequence. During this sequence, the module requests an IP
address and a Þlename from the BootP server. The module then requests a TFTP
of the Þle and receives the download of the image. The module will not function
until the Flash image is downloaded from the BootP and TFTP server.
If a BootP and TFTP are not intended at this time, this process may be stopped by
resetting the module. Resetting is done by pushing the reset button on the
module, power cycling the chassis, or removing the module from the chassis and
re-inserting. (See section titled
The Reset Switch
on page 2-8.) After resetting, the
module again looks for a BootP server, but will time-out after about four minutes.
After the time-out the module then boots from Flash memory. The next time the
power is cycled, the module will boot from Flash memory and not request the
BootP server.
Installing GPIMs
Four GPIMs may be installed into the 9G536-04. All GPIMs are installed in the
same manner, as listed in this procedure.
Refer to Appendix A for cable speciÞcations for the GPIMs.
The GPIMs are installed into the SmartSwitch 9000 module as follows:
1. Attach the antistatic strap (refer to the instructions in the antistatic wrist strap
package) before removing the GPIM from the antistatic packaging.
2. Remove the GPIM from the packaging.
3. Hold the GPIM with the network connection port facing away from the
SmartSwitch 9000 module. The 20-pin connector should be facing towards the
empty GPIM slot, with the wide part of the connector oriented up in relation
to the printing on the SmartSwitch 9000 module. See Figure 2-2 to orient the
GPIM 20-pin connector.
