System reliability considerations
To help ensure proper cooling and system reliability, make sure:
Each of the drive bays has either a drive or a filler panel installed.
Each of the power supply bays has either a power supply or a filler panel
installed.
The cover is in place during normal operation.
Note: The front door (tower model) can be permanently removed without
affecting system reliability.
Be sure to leave space around the server to allow the server cooling system to
work properly.
– On a tower model, leave about 127 mm (5 in.) of space around the front
and rear of the server.
– On a rack model, refer to the documentation that comes with the rack.
The cover is removed for no longer than 30 minutes while the server is
operating.
A removed hot-swap drive is replaced within two minutes of removal.
Cables for optional adapters are routed according to the instructions provided
with the adapters.
A failed fan is replaced within 48 hours.
