Figure 37 (page 74)).
3. Disconnect cables from the faulty core switch blade.

Installing a core switch blade (CR8)
CAUTION: Wear a grounded ESD strap when handling a CR8 blade. Use the grounding
connections above the power connectors on the chassis.
To install a CR blade (slot 5 or 6):
1. Open the ejector handles to approximately 45 degrees, and then orient the CP blade so that
the handles are toward you and the flat metal side is on your left.
2. Align the flat metal side of the core switch blade inside the lower and upper blade guides in
the slot, and then slide the core switch blade into the slot until it is firmly seated (see
Figure 37 (page 74)).
3. Using the Phillips screwdriver, tighten the thumb screw inside each handle.
4. Power on the core switch blade by sliding the ON/OFF switch in the top handle up, to cover
the thumb screw.
5. Verify that the power LED is green (this can take a few seconds). If not, ensure that the core
switch blade has power and is firmly seated, and that the ejectors are in the locked position.
6. Connect to the new core switch blade.
7. Pack the faulty core switch blade in the packaging provided with the new core switch blade
and contact your DC SAN Director supplier for the procedure for returning the faulty blade.
