I'm preparing for DES-4421 Exam, so I practice with Dell EMC Certification Exam from Dell site (https://education.dellemc.com/content/emc/en-us/home/certification-overview/find-exam.html)
I keep struggling with one question and cant get correct answere, could someone enlighten me with the knowledge for following question,
An administrator attaches all six PSUs of an MX7000 chassis to the rack active PDU. What is the correct power on sequence taken by the chassis?
Ps. I've already read all White Papers but still dont get it.
I believe the answer you're looking for is on page 9 here, which states the power supplies are the first.
Hope this helps.
I've already read that couple of times but still I miss some information.
I tryied out alot of different order's but still I cant get the correct answere.
That's my orders
1 - EC Uboot starts
2 - PSU firmware starts
3 - Fabric D powers on
4 - LCD powers on and displays WAIT message
5 - LCD panel loads
Could you please correct me, what and why its wrong ?
