Removing the blade-server bezel assembly
Before you can replace a defective system-board assembly or blade-server bezel
assembly, you must first remove the blade-server bezel assembly. The following
illustration shows how to remove the bezel assembly from a blade server.
Complete the following steps to remove the blade-server bezel assembly:
1. Read the safety information beginning on page vii and “Installation guidelines”
on page 39.
2. Open the blade server cover.
3. Press the bezel-assembly release and pull the bezel assembly away from the
blade server approximately 1.2 cm (0.5 inch).
4. Disconnect the control panel cable from the control panel connector.
5. Disconnect the serial cable from the serial connector.
6. Pull the bezel assembly away from the blade server.
7. Store the bezel assembly in a safe place.
Installing the IDE hard disk drive
The blade server has a connector on the system board for installing a 2.5-inch
integrated drive electronics (IDE) hard disk drive. The BladeCenter QS20 model
comes with the IDE hard disk drive already installed.
Note: Some hard disk drives have Phillips screws; therefore, make sure that a
Phillips screwdriver is available.
Attention: To maintain proper system cooling, do not operate the BladeCenter
unit for more than 1 minute without a blade server or filler blade installed in each
blade bay.
