Removing the cover (Model 225)
To remove the appliance top cover:
1. Review the information in “Before you begin” on page 27.
2. If you are planning to install or remove any part other than a hot-swap hard disk
drive or hot-swap power supply, switch OFF the appliance and all attached
devices and disconnect all external cables and power cords.
3. Release the left and right side latches and pull the appliance out of the rack
enclosure until both slide rails lock.
Note: When the appliance is in the locked position, you can reach the cables
on the back of the appliance.
4. Move the cover-release lever down while sliding the top cover toward the rear of
the appliance about 25 mm (1 in.). Lift the cover off the appliance and set the
cover aside.
Attention: For proper cooling and airflow, replace the cover before switching
on the appliance. Operating the appliance for extended periods of time (over 30
minutes) with the cover removed might damage appliance components.
