Chapter1 Using a Fabric Extender with a Cisco Nexus 5000 Series Switch
Cisco Nexus 2248TP
You can order the Cisco Nex us 2248TP FEX with AC power supplies that have front-to-back or
back-to-front airflow for cooling or DC power supplies that offer front-to-back airflow. The
back-to-front airflow components have a black stripe on their front surface for easy visual identification.
The front-to-back airflow components do not have a black stripe.
Caution Be sure that all of the power supply and fan tray modules in the same chassis have the same airflow
direction and that the air inta ke for those modules is positi oned on a cool aisle. If you inst all a module
that uses a different direction of ai rflow from the other modules in your system, you will see an er ror
message. If you position a chassis with its modules taking cooling air from a warm aisle, the switch can
reach an overtemperatu re state and shut down.
If one power supply is installed in the chassis, but the other power supply slot is empty, you should use
a blank filler panel (part number N2200-P-BLNK) to cover the empty slot. Figure1-15 shows a blank
power supply filler panel.
