Roger Federer will lead Switzerland's mission to win promotion back to the Davis Cup World Group when his team tackle Australia in Sydney next week.
The deadline for player nominations isn't until Tuesday, but the Swiss have already confirmed their team line-up for the play-off tie at the Royal Sydney Golf Club from September 16-18.
Swiss captain Severin Luthi has announced a full strength squad that sees Federer named alongside Olympic gold medal-winning partner Stanislas Wawrinka, Stephane Bohli and Marco Chiudinelli.
Federer missed Switzerland's defeat to Kazakhstan in 2010 which spelt relegation, but a 5-0 victory over Portugal in July put them back into the play-offs with the world number three back in the line-up.
Switzerland have never defeated Australia in four previous Davis Cup meetings.
Australia will have Wimbledon quarter-finalist Bernard Tomic in their line-up while new captain Patrick Rafter, who is yet to announce his team, will be hoping that Lleyton Hewitt will be fit after he was forced to withdraw from the US Open with a recurring foot injury.
