How to lashing cisco MDS 9124e Fabric Switch firmware

[SOHBG]

I have a few quries after reading through the user guide:
1. If I flash the switch using cmd:
install all kickstart
bootflash:boot-xxx
bootflash:isan-xxx

where should I placed the firmware? Currently, I have a dhcp server which give ip to my C7000 enclosure with cisco switch in ethernet bay 3 and 4.

2. Can the password be removed after I assisgn one? by pressing reset button? I intent to rmv the password after flashing.

Do give me some guidance as this is the first time I encounter this switches. Thanks.
