Overview2
Connecting HA Servers to the Switch describes connectivity requirements 
and recommendations specific to CMS High Availability (HA) systems. This 
information is applicable to the following 
DEFINITY Release 8.1 switches:
•Generic 3si (G3si) 
•Generic 3r (G3r)
•Generic 3csi (G3csi)
•Prologix Release 3 (G3csi)

2. Customized software switch-over 
If the HA primary and secondary servers connect to CMS clients 
and other peripherals, such as NTS servers, printers, etc. over the 
same network subnet, LAN traffic on this “user” network can be 
automatically redirected from the primary to the secondary server by 
means of customized scripting tools. The scripts, which are set up 
by PSO,...

ACD traffic is routed through dual control C-LAN circuit packs on the 
switch. The Definity switch must be administered to enable the dual C-
LAN cards; for details about the administration of dual ACD links on HA 
systems, see “Administering the Switch for CMS High Availability 
Systems” on Page 4-1. 
Finally, note that the parts requirements and physical connection 
schemes...

c. Direct connect to Customer LAN, without private segment:
— Least preferred option
— Complete dependency on performance and reliability of 
customer’s LAN
— Allows remote location of endpoints when customer LAN 
connectivity is convenient 
— Customer LAN administrator must be present during setup

Overview2The recommended link setup for HA systems consists of a private LAN 
connection between switch and server, with no connectivity to other 
customer LAN segments. This arrangement optimizes performance of 
ACD traffic over the link and eliminates potential points of failure 
extraneous to the needs of...

A depiction of an ideal HA system configuration for a single-ACD system 
is displayed in the following figure. 
Note:
Existing customer network configurations are likely to require a different 
LAN setup from the idealized configuration shown above. This is 
particularly likely when mutliple ACDs are conncected to the CMS server. 
For information about...

Distance Limits2The maximum allowable length for a single segment of Cat 5 cable is 100 
meters (328 feet); a maximum of four hubs can be used in series to 
connect cable segments. Therefore, the distance between a local switch 
and server must not exceed a maximum distance of 500 meters (1,640 
feet). 
However, when multiple ACDs are in use, few, if any,...
