Under-18s Coach Wants To See Fight And QualityTickets for the match are £3 for Adults, £1 for Concessions and FREE for Under-16s.
"The players have got to deal with different conditions and different environments," said Dawes.
"We had a bit of that in the Telford game where Telford brought a few supporters.
"They were loud and supported the team and I thought a few of us wobbled because they weren't used to that.
"They've had that experience now and I hope that on Wednesday they handle it a bit better.
"It's all down to the players then, who can handle the situation the best and who can show quality while showing fight at the same time.
"We have to make sure we perform and win the game of football."
That match was played in front of over 400 fans, and Dawes insists his side must deal with all of the conditions thrown at them at Ilkeston.
Town beat near rivals AFC Telford United 2-1 after extra-time in the First Round Proper clash at Greenhous Meadow in October.
"It's going to be a tough game," said Dawes.
"We watched them on a DVD when they played and beat Burton (Albion).
"I know they won on penalties but they deserved the win and were very good in the game.
"We've got to make sure that we've got as much fight as them and we've got to make sure that we've got more quality than them on the day to get through to the next round.
"I've watched them and I've spoken to people about them and people speak highly of them - they're no mugs.
"I don't think there's bad players in their team. They're well organised and it will be a tough game.
"We're approaching the game as if it's any other game in the league."
But Dawes, head of academy coaching, believes Ilkeston, who beat Burton Albion at home on penalties in the First Round Proper, will prove strong opponents for his side on Wednesday.
The young Shrews take on the Robins in the Second Round Proper clash at New Manor Ground (7.45pm kick-off) knowing victory would second up a Third Round Proper tie at home to Newcastle United.
Ian Dawes insists Shrewsbury Town must show 'fight' and 'quality' if they are to progress past Ilkeston in the FA Youth Cup on Wednesday night.
