9.4 8260 18-Port Active Module Switching Module

This module is identical to the 18-port active per-port switching module with the
exception that it does not support the per-port switching feature. This means
that all the ports on this module can only be assigned to the same segment on
the backplane or can all be isolated.

9.4.1 Configuring the 18-Port Active Module Switching Module

Configuration of this module is identical to the configuration of the 18-port active
per-port switching module with the exception that you must assign the module to
a backplane segment or an isolated network using the following command:
SET MODULE {slot.subslot} NETWORK {network}

9.5 8260 20-Port Passive Module Switching Module

This is a single slot module that supports 20 passive ports. This is a module
switching module, which means that all the ports must be attached to the same
segment. The main features of this module are:
180
8260 Multiprotocol Intelligent Switching Hub
required. If a trunk fault appears which disrupts phantom drive, the trunk
will wrap immediately. The module never goes to beacon recovery
because the problem is corrected before that happens. If, for any
reason, phantom is not disturbed by the fault, beacon recovery is
initiated as in No. 1 above.
To set the compatibility mode for a trunk, you can use the following
command:
SET TRUNK {slot} RING_IN COMPATIBILITY_MODE {mode} or
SET TRUNK {slot} RING_OUT COMPATIBILITY_MODE {mode}
If ports 17 and 18 are configured as RI/RO trunks, they can be
enabled/disabled using the following command:
SET TRUNK {slot} RING_IN MODE {enable|disable} or
SET TRUNK {slot} RING_OUT MODE {enable|disable}
Each port can be enabled/disabled using the following command:
SET PORT {slot.port} mode {enable|disable}
20 ports with shielded RJ-45 connectors.
A single DPLL which is implemented on the module will remove the jitter
before passing the signal to the 8260 backplane. Note that unlike the active
modules, the individual ports do not have their own DPLL.
The module can be assigned to any of the 10 token-ring segments on the
ShuntBus or can be isolated. When isolated, all the stations attached to this
module can communicate with each other but not with the stations attached
to the other modules.
Support for both UTP and STP cabling. However, you cannot mix both
cabling types on the same module simultaneously.
Support for beacon recovery using the Recovery ASIC which is implemented
on the module. For more information about beacon recovery support on the
