Configuring The 20-Port Passive Module; Port Passive Module Module Side View - IBM Nways 8260 Manual

Figure 112 shows the side view of the 20-port passive module. As can be seen,
in addition to the 11 isolated segments and the mounting for one T-MAC, there is
an 8-position DIP switch located on the module. These DIP switches are used in
the absence of an installed management module in the 8260. However, if a
management module is installed in your 8260, the setting of these DIP switches
will be ignored unless DIP_CONFIGURATION is enabled for DMM. For more
information, please refer to 4.2.4.4, " Configuring DMM Device" on page 50.
Figure 112. 20-Port Passive Module Module Side View
The DIP switch settings for this module are identical to the 18-port active
per-port switching module (described in 9.3.1, "Configuring the 18-Port Active
Per-Port Switching Module" on page 177) with the following exception:

9.5.1 Configuring the 20-Port Passive Module

To configure this module you must do the following:
1. Set beacon threshold for the module.

Port Status Green
Use DIP switch position 6 to enable (OFF) or disable (ON) the speed
detection on the passive module. For more information about the speed
detection algorithm used by the 20-port passive module please refer to 8.8.2,
"Speed Detection on Passive Modules" on page 149.
When a beaconing condition is detected on a port, the port is wrapped by the
Recovery ASIC. The port is unwrapped when a transition of phantom is
detected or when the port is disabled and then re-enabled by the user.
