The recommended link setup for HA systems consists of a private LAN
2
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 switch-to-server communication. However,
this configuration may not be feasible for many, if not most, CMS
customers who adopt the HA option.
There are two basic ways to make the LAN connection between the
Definity switch and the server:
• Connecting with a 10Base-T hub and Cat 5 Cables
2
The recommended method to connect the switch-to-server link uses
a 10Base-T hub and unshielded twisted pair UTP Category 5
cabling to directly connect switch and server over a private LAN.
• Connecting with a Crossover Cable
Direct switch-to-server connectivity can be accomplished using a
crossover cable with flipped transmit/receive leads. This method has
the advantage of ensuring that the LAN connection is private, since
a hub is not included in the configuration, but is not recommended
for HA systems.
If the customer requires a link connection by means of crossover cables
or other methods not described above, general descriptions and
requirements for alternate connectivity setups are described in CentreVu
Call Management System Switch Connection and Administration (585-
215-876).
Ideally, a second ethernet card should be installed on each CMS HA
server. If two ethernet ports are available, the standard provisioning
procedure is to use the first (built-in) ethernet port for connectivity to the
customer LAN or public network. The second ethernet card (Fast-SCSI
