Important Notes Table 3: SAN Director 2/128 Information SAN Director 2/128 CP blade Power supplies Card seating Description The SAN Director 2/128 CP contains electronics that provide internal routing bandwidth, and are always active on both CPs. Removal of a CP might affect user performance and therefore should not occur until a replacement CP is ready to be installed. A fully configured SAN Director 2/128 with eight port cards and two CPs is capable of running on a single power supply. Therefore, two power supplies provide 2N redundancy. To maintain redundancy of AC input, one power supply must be in an even-numbered slot and one in an odd-numbered slot. The default configuration is for the power supplies to be in slots 1 and 2. Follow the procedure below to ensure that Port Cards and Control Processor (CP) cards are properly installed into your SAN Director 2/128: 1. Install the leading edge of the CP or Port Card into the appropriate slot on the card cage. 2. Push the front surface of the card (SFP cage side) carrier near the center with your hand until the top and bottom ejectors engage the upper and lower ejector plates (do not hold onto the ejectors as you push). 3. Press down on both ejectors at the same time with equal force to seat the blade. 4. Tighten the top thumb screw first. SAN Director 2/128 Fabric OS 4.2.x Release Notes 13
