The DIP switches let you perform the following:

Use DIP switch positions 1 through 4 to assign all the ports on the module to one of the backplane segments or isolated-1 segment. Note that when using DIP switches, all the ports will be assigned to the same segment, so you cannot do per-port switching when using DIP switches for configuring your 8260 modules.

Table 29 shows the meaning of settings for DIP switches 1 thru 4:

By default, the module is shipped from the factory with the DIP switches set for token_ring_1.

Use DIP switch position 5 to choose if the module is going to use the

Non-Volatile RAM (ON position) or DIP switch settings (OFF position) for its configuration. Note that if there is a management module installed in the 8260, this DIP switch determines which configuration (NVRAM or DIP switch setting) will be sent to the management module. The actions taken by the management module, upon receipt of this information are described in 4.2.4.4, ª Configuring DMM Deviceº on page 50. Bydefault, DIP switch 5 is set to NVRAM.

Use DIP switch position 8 to set the ring speed to 4 Mbps (ON) or 16 Mbps (OFF). The module is shipped from the factory with the speed set to 16 Mbps.

9.3.1Configuring the 18-Port Active Per-Port Switching Module

To configure this module you must do the following:

1.Before installing the module in the 8260, use the onboard jumpers on the module to determine whether ports 17 and 18 are used as lobe ports or RI/RO trunk ports. The onboard jumpers are shown in Figure 110 on page 178.
