When you install a replacement fan, the cooling load is distributed back evenly across
both the fans, and the Hardware Fault LED stops blinking and the alarm turns off.

The Junos Space JA2500 appliance ships with six hard disk drives in RAID 10 array
configuration. The hot-swappable drives are externally accessible in field-replaceable
trays. You can remove and replace a hard disk without powering off the appliance or
disrupting any functions performed by the appliance. If a hard drive fails, the Hard Disk
Fault LED on the hard disk turns on and an alarm sounds.
