Load Balancer prerequisites

•Before you configure a Load Balancer to connect to the Office Communications Server Enterprise pool, ensure you configure the following:

—The Load Balancer must meet the Microsoft criteria for a Load Balancer. See "Load Balancer requirements" (page 44)

—Configure a static IP address for servers within your pool.

—For each server within the pool a certificate, include for both user and server authentication issued by a certification authority in the pool’s local domain.

—Configure a VIP address and a DNS record for the load balancer.

—Test users created and SIP-enabled in the pool.

—Install root certificate from CA in the domain (or trusted CA) on client computers.

—Log on to all servers in the pool using TLS to ensure server and client certificates work.

—Configure Port 135 on Load Balancers to enable server-side block and allow functionality for users and move user scenarios to pools through DCOM. For example, perform remote DCOM-based database operations. Nortel recommends the minimum configuration.
