Removing a core switch blade (CR16-8)
The SAN768B-2 continues to operate while a core switch blade is being replaced.
Attention: Follow ESD precautions (see “ESD precautions” on page xix)
whenever handling blades.
Note: The CR16-8 blade is compatible only with the SAN768B-2
Complete the following steps to remove a CR blade.
1. Remove the chassis door (see “Removing and installing the chassis door” on
page 81).
2. Unscrew the two thumb screws from the ejectors on the blade using the
Phillips screwdriver. Unscrew the top thumb screw until it pops out. This
initiates a hot-swap request.
3. Label and then disconnect cables from the faulty core switch blade.
4.
Open the ejectors by rotating them toward the center of the blade face. Pull the
blade out of the chassis using the ejectors. (see Figure 34 on page 100).
