Removing the DPI blade from the BladeCenter unit
The following illustration shows how to remove a DPI blade from a BladeCenter H
or HT unit. The appearance of your BladeCenter unit might be different. See the
documentation for your BladeCenter unit for additional information.
Attention:
v To maintain proper system cooling, do not operate the BladeCenter unit without a
blade server, DPI blade, or filler installed in each blade bay.
v
When you remove the DPI blade, note the bay number. Reinstalling a DPI blade
into a different bay from the one it was removed from can have unintended
consequences. Some configuration information and update options are
established according to bay number; if you reinstall the DPI blade into a
different bay, you might have to reconfigure the DPI blade.
To remove the DPI blade, complete the following steps:
1. If the DPI blade is operating, unbind it from the ASM. This turns off the DPI
blade. If the DPI blade is not bound or assigned, press the power-control/unbind
button (behind the DPI blade control panel door) to turn off the DPI blade. See
“Control panel buttons and LEDs” on page 4 and “Turning off the DPI blade” on
page 5 for more information.
2. Open the two release handles as shown in the illustration. The DPI blade
moves out of the bay approximately 0.6 cm (0.25 inch).
3. Pull the DPI blade out of the bay.
4. Place either a filler or another blade in the bay within 1 minute.
5. If you are instructed to return the DPI blade, follow all packaging instructions,
and use any packaging materials for shipping that are supplied to you.
