The hosts Brazil have not qualified for the competition's elite category since 2003, despite being progressing into the playoff round in each of the past seven years.
Colombia is aiming for its first appearance in the world group.
Brazil's world No.45 Thomaz Bellucci said the team had concentrated on serving during training on relatively fast-paced courts.
"Every day we have been working hard on our serves because if we can get that right, we are halfway towards winning the tie. After training I have been hitting at least 50-60 serves to sharpen up for the tie." Bellucci said.
Bellucci will be joined in the singles by world No. 102 Joao Souza while Bruno Soares will partner Marcelo Melo in the doubles. Captained by Marc Gorriz, Colombia will be represented in the singles by Santiago Giraldo and Alejandro Falla, ranked 55th and 56th respectively. Robert Farah and Juan Sebastian Cabal will compete in the doubles.
