Overview
The following figure shows the switch features on the power supply side of the chassis.
Figure 2: Chassis Features on the Power Supply Side of the Chassis
1 Power supply modules (1 or 2) (AC power supplies shown)
with slots numbered 1 (left) and 2 (right)
2 Fan modules (4) with slots numbered from 1 (left) and 4 (right)
3 Beacon (BCN) and Status (STS) LEDs
4 USB ports (2)
You can use the 1- and 10-Gigabit ports to connect this switch to up to 48 devices or to Nexus 2000 Series
FEXs, which can be connected to additional servers (for the number of FEXs that can be supported, see the
release notes for the NX-OS software that you are using). You can connect any of the supported FEXs to the
downlink ports.
For installation information on the Cisco Nexus 2000 Series FEXs, see the Cisco Nexus 2000 Series Hardware
Installation Guide. For information on a B22 FEX, see the Getting Started Guide for that FEX model.
Depending on whether you plan to position the ports in a hot or cold aisle, you can order the fan and power
supply modules with port-side intake or port-side exhaust airflow. For port-side intake airflow, the fan and
AC power supply modules have burgundy coloring (DC power supply modules have green coloring). For
port-side exhaust airflow, the fan and AC power supplies have blue coloring (DC power supply modules have
gray coloring). You can also order the 1200-W HVAC/HVDC power supply which has dual-direction airflow
with white coloring. Dual-direction airflow modules automatically use the airflow direction of the other
modules installed in the switch.
The fan and power supply modules are field replaceable and you can replace one fan module or one power
supply module during operations so long as the other modules are installed and operating. If you have only
one power supply installed, you can install the replacement power supply in the open slot before removing
the original power supply.
