Step 8 Replacing a Cisco Nexus Fabric Fan Tray The Cisco Nexus system has two fabric fan trays located on the backside of the chassis immediately above the fabric modules see Figure on page Place an antistatic mat or antistatic foam where you can place the fan trays. Align each of the two front doors on a side of the mid frame area, and attach it by screwing in three Step 1 screws as shown in Figure Re-align the EMI frame to the air intake area on the chassis and screw its four captive screws to the chassis, and tighten the captive screws to 8 in.

You can replace the optional air filter while the Nexus system is operational. Note Only the Cisco Nexus device includes an optional air filter. To replace the air filter, follow these steps: On the left and right side of the existing air filter, loosen the two captive screws so they are no longer Step 1 attached to the chassis. Release the spring pin and make sure that it holds the air filter on to the EMI frame. Screw in and tighten both captive screws, one on each side of the air filter.

Technical Specifications This appendix describes the technical specifications for the Nexus system and includes these sections: Cisco Nexus Power Specifications for the Cisco Nexus Series Devices The number of power supplies that a Cisco Nexus Series switch requires depends on the quantities and types of modules that you include in the switch chassis.

The amount of power available for use with your Cisco Nexus Series device depends on the number of power supply units, input voltage used, and the power mode used.

To determine the amount of A fourth power supply unit can be added to only the Cisco Nexus device. The Cisco Nexus holds up to three power supply units. Table A-8 Power Availability for 7. For the Cisco Nexus switch, the side-to-side airflow requires 11 inches The Cisco Nexus switch uses front-to-back airflow as shown in Figure Airflow for cooling the power supply units To allow for the Cisco Nexus switch to take in air from the cold aisle and floor on the right side, you should route cables on the left front side of the device.

If necessary, you can route cables on the upper right front side of the chassis, which leaves the lower right side open to cooling air from the cold aisle in front of the chassis. This appendix includes the following sections: The management port link is bad and has been disabled due to a hardware Amber failure. The module has not detected a signal.

The module does not detect a link. The port is disabled by the operator or is not initializing. Blinking The port is faulty and disabled. Self-diagnostic tests have failed or another power supply failure has occurred. Blinking blue The operator has activated this LED to identify this module in the chassis. This module is not being identified. The fan tray is receiving insufficient power.

No power is going to the fan tray. The system is powered down when the LEDs on each power supply are all off. Repacking the System Components You should repack the Cisco Nexus Series system in the packing materials in which it was originally shipped.
