• Phillips screwdriver #2 (cross-head )
• Small flat-bladed screwdriver
• Jumper removal tool
• Anti-static wrist strap
Removing the Top Cover
To remove the cover, follow these steps:
1. Turn off all peripheral devices connected to the server.
2. Power down the server by pressing and holding the Power button on the
Front Control Panel. You may have to hold the Power button down for
several seconds.
3. Disconnect the power cord and any Ethernet line.
4. Pull the server out of the rack.
5. Loosen the thumbscrew at the front of the chassis that secures the 120 mm
fan bay and fold the fan cover open.
6. Loosen the two thumbscrews that secure the top cover to the rear of the
chassis and fold the rear half of the top cover open.
7. Loosen the screw that secures the non-hot plug PCI adapter board cover
and remove that cover.
8. Place your hands on the sides of the chassis near the hinge of the rear part
such that your thumbs can aggressively slide the entire top cover toward
the rear of the chassis. Sliding the cover in this direction disengages the
hooks on both sides of the top cover from the chassis housing.
