The M5800 is carrying your entire network. One power supply failure and you're down, full stop. Unless you've got a hot-swap spare ready.
This PSU drops into the M5800 while it's still running. Pull the old one, seat the new one, traffic keeps flowing. No reboot. No downtime window. No 'sorry, we'll be back in 20 minutes' email to the whole office.
OEM spec for the M5800 chassis. If you're running a dual-PSU setup or just want that spare sitting on the rack shelf before the first unit croaks, this is the one to grab
