Configuring Redundant Switching Hubs

Redundant switching hubs enhance system redundancy and resiliency by providing a backup capability to the primary public switching hub.

•Package style for the NX5820 redundant public switching hub is NX5000-RDT which includes the following items:

Component	Description	Quantity
Style Name
VX5000–SWH	Switching hub (Bay Networks)	1
CBL24–1	Ethernet 10Base-T (B to B) cable	1
	assembly, 1 meter

•Order above redundant public switching hub options as necessary. The maximum number is unlimited.

Configuring Additional Displays

The following considerations apply when configuring additional displays:

•One monitor with keyboard and mouse is provided with the primary SCP (style NX5820-SCP for NX5820 and NX5820 K systems). This monitor is shared with the servers.

•A second monitor with keyboard and mouse is provided with the redundant SCP option (style RNX5820-SCP for NX5820 and NX5820 K systems).

•Up to six PC-based operator display workstations (ODWs) can be connected to both the internal maintenance hub (private LAN) and the internal switching hub (public LAN) for operator display terminal (ODT) and maintenance use. For instructions to install software products and configurations for the ODW in a Windows NT environment, refer to ClearPath Enterprise Server NX Series with Windows NT Implementation and Operations Guide (8807 6542).

Note: ODWs are a client responsibility. Requirements are listed below.
