Connecting HA Servers to the Switch
CentreVu
CMS R3V8 High Availability
Connectivity, Upgrade and Administration
Overview 2-3
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 described in this chapter are applicable to each switch-to-
server link installed on the HA system, irrespective of the total number of
links connected to the server.
Connecting
Blocks
2
In this chapter, references are made to 103A connecting blocks, which
have one RJ45 connector per block. If needed, you can substitute
the 104A connecting block, which has two RJ45 connectors per block.
The wiring for both connecting blocks are identical.
Planning for LAN
Switch Links
2
When setting up a switch link over a LAN, planning information must be
gathered before you begin. You should also take into account if the
Intuity™ AUDIX
®
product will be part of the LAN. You must coordinate
the setup of that system with the switch and the CMS. Some of the
information needed includes:
• How is the connection being made from the CMS computer to the
switch:
a. Private LAN, no connectivity to customer LAN (uses private
LAN addresses):
— Recommended option for HA systems, most robust and
reliable, no dependency on customer’s network
— Hubs are used to make the connections; up to four hubs
can be used to extend distances
— Crossover cable can be used instead of hubs (with flipped
transmit/receive leads)
b. Customer LAN with private segment:
— Uses switch or router to provide a private collision domain
— Minimal dependency on customer’s network
— Customer must provide equipment and administer
network for private segment
— Customer LAN administrator must be present during setup
