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