Chapter 2 Using a Fabric Extender with a Cisco Nexus 7000 Series Switch
Cisco Nexus 2232TM FEX
•
DC power supply with front-to-back airflow (N2200-PDC-400W)
• DC power supply with back-to-front airflow (N2200-PDC-350W-B)
If you have only one power supply in a chassis, then you must install a blank filler plate
(N2200-P-BLNK) in the open slot to maintain the designed airflow.
For more information on these power supplies, see the “Power Supplies for the Cisco Nexus 2248TP-E
FEX” section on page 2-4 and the power supply specifications in the “Power Specifications” section on
page B-1 . To replace one of these power supplies, see the “Removing and Installing Power Supplies”
section on page 3-17 .
Fan Tray for the Cisco Nexus 2232TM FEX
The Cisco Nexus 2232PP and 2232TM FEX use the same fan tray, which you can order with either
front-to-back airflow (N2K-C2248-FAN) or back-to-front airflow (N2K-C2248-FAN-B). The fan tray
includes a status LED that indicates whether the module is operational. You can hot swap the fan tray
during operations as described in the
“Removing and Installing the Fan Tray” section on page 3-20 .
Figure 2-19 shows the fan tray with front-to-back airflow (no black stripe across the front), and
Figure 2-20 shows the fan tray with back-to-front airflow (black stripe across the front).
