Eastleigh boss Ben Strevens admitted the pressure of his side’s 3-0 win over Stourbridge was the most he has felt in management.
National League side Eastleigh had to wait until the second half to get the breakthrough with Scott Rendell’s 50th minute penalty.
Sam Smart and Reda Johnson goals – combined with Jordan Williams’ red card for Stourbridge – sealed a second-round home tie with Crewe.
“I’m massively pleased for everyone associated with our football club,” said manager Strevens.
“It’s probably the most pressure I’ve ever felt as a manager given the reward.
“We can really look forward to welcoming Crewe here and what a day that’ll be.
“Earning a few quid is massively welcome for any club but the opportunity to test ourselves is something we’re relishing.”
Rendell opened the scoring when Smart was upended by Williams, who saw red when conceding the free-kick from which Smart made it 2-0.
Johnson lashed home late on as Southern League Premier Division Central Stourbridge were left to rue missed opportunities.
“I can’t fault my lads, but football is all about taking your chances when they come,” said manager Ian Long.
“When you add in that they’re the full-time club, and at home, it might have ramped up the pressure.
“Once they score, it’s an uphill battle and then when you lose a man, it really does become an almost impossible task.”
