Page 4 - Moving Server Chassis; Installation Guidelines

Moving Server Chassis When lifting the chassis, be aware of its weight, and follow these guidelines: Do not try to lift the chassis using the handles on the side. These handles are intended only for movingand adjusting the chassis position. Caution • Never lift the chassis alone — Always use two peo...

• Ensure that circuits are sized according to local and national codes. For North America, the power supplyrequires a 20 A circuit. To prevent loss of input power, ensure that the total maximum loads on the circuits supplying power tothe chassis are within the current ratings for the wiring and brea...

Both grids in a power redundant system should have the same number of power supplies. If your system is configured for grid redundancy,slots 1 and 2 are assigned to grid 1 and slots 3 and 4 are assigned to grid 2. If only two power supplies (PS) are in a redundant- modechassis, they should be in slo...

Step 7 Replace the terminal cover as shown. This cover should always be in place when power is applied to theterminals. Step 8 Connect the other end of the power wires to a DC-power input source. Step 9 Set the DC disconnect switch in the circuit to ON. In a system with multiple power supplies, conn...

Page 20 - Proper FEX and Fabric Interconnect Port Connectivity

Linking a chassis to two fabric port channel port groups is disruptive and does not affect the VIF namespaceunless it is manually acknowledged. The VIF namespace is then automatically set to the smaller size fabricport channel port group usage (either 63 or 118 VIFs) of the two groups. Caution For h...
