Removing a core switch blade
The DC04 SAN Director continues to operate while a core switch blade is being replaced.
CAUTION: Wear a grounded ESD strap when handling a CR4S-8 blade. Use the grounding
connections above the power connectors on the chassis.
NOTE: The CR4S-8 blade is compatible only with the DC04 SAN Director.
To remove a CR4S-8 blade:
1. Remove the chassis door. See Removing the chassis door (page 65).
2. Power off the blade by sliding the slider switch in the left ejector to the right to the off position
(see Figure 39 (page 76)).
3. Disconnect cables from the faulty core switch blade.
4. Use the Phillips screwdriver to unscrew the thumb screw from both ejectors.
5. Open both ejector handles simultaneously to approximately 45 degrees and remove the core
switch blade from the chassis (see Figure 39 (page 76)).

Installing a core switch blade
CAUTION: Wear a grounded ESD strap when handling a CR4S-8 blade. Use the grounding
connections above the power connectors on the chassis.
To install a CR4S-8 blade (slot 3 or 6):
1. Open the ejector handles to approximately 45 degrees, and then orient the CR4S-8 blade so
that the handles are toward you and the flat metal side is on the bottom.
2. Align the flat metal side of the core switch blade inside the left and right blade guides in the
slot, and then slide the core switch blade into the slot until it is firmly seated (see
Figure 39 (page 76)).
3. Use the Phillips screwdriver to tighten the thumb screw inside each handle.
4. Power on the core switch blade by sliding the ON/OFF switch in the left handle to the left 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.
