∙

18-port Active Per Port Switching Module

18-port Active Module Switching Module

Dual Fiber Repeater Module

20-port Passive Module Switching Module

Jitter Attenuator Daughter Card

9.1 Introduction

The 8260 token-ring modules can only be connected to the token-ring segments on the ShuntBus. They cannot be attached to the token-ring segments on the Enhanced TriChannel. You can also install and use any 8250 token-ring module in the 8260 multiprotocol intelligent switching hub. The 8250 token-ring modules can only be connected to the token-ring segments on the Enhanced TriChannel. Therefore, a token-ring segment on the 8260 can consist of 8250 or 8260

token-ring modules. However, you may use RI/RO connections, bridges or routers to connect the 8260 token-ring segments consisting of 8260 modules to the token-ring segments consisting of 8250 modules.

For information about 8250 Ethernet modules please refer to IBM 8250 Intelligent Hub and IBM HUB Management Program/6000,GG24-4033.

9.2 Configuring Token-Ring Network Parameters

Before discussing the individual 8260 token-ring modules and how to configure them, this section describes the parameters that may be configured for each network segment to which the 8260 token-ring modules and ports are to be attached.

The following is the summary of parameters that may be configured for each token-ring segment:

∙Enable/disable automatic beacon recovery

Use the following command to enable/disable the automatic beacon recovery for each segment to which the ports or modules are to be attached:

SET NETWORK {network} BCN_RECOVERY {enabledisable}

Note that if you disable this feature, any beacon condition on the network will disrupt the operation of the network until you remove the source of beaconing from the ring.

∙Set the ring speed

You must set the ring speed for the backplane or isolated segment using the following command:

SET NETWORK {network} RING_SPEED {4_mbps16_Mbps}
