Replacing the DPI blade cover
Attention: You cannot insert the DPI blade into the BladeCenter unit until the
cover is installed and closed. Do not attempt to override this protection.
The following illustration shows how to install the DPI blade cover.
To install the DPI blade cover, complete the following steps:
1. Read the safety information that begins on page v and “Installation guidelines”
on page 25.

of the DPI blade, as shown in the illustration.
5. Pivot the cover to the closed position, as shown in the illustration, until it clicks
into place.
