The 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 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

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

Ethernet Ports on a CMS Computer

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 Buffered Ethernet (FSBE) or SunSwift* ethernet) should be dedicated solely to the switch link.
