Chapter 1 Using a Fabric Extender with a Cisco Nexus 5000 Series or Cisco Nexus 6000 Series Switch
Cisco Nexus 2248TP-E
You can order the Cisco Nexus 2248TP-E FEX with AC power supplies that have port side exhaust or
port side intake airflow for cooling or DC power supplies that offer port side exhaust airflow. The port
side intake airflow components have a black stripe on their fan side surface for easy visual identification.
The port side exhaust 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 intake for those modules is positioned on a cool aisle. If you install a module
that uses a different direction of airflow from the other modules in your system, you will see an error
message. If you position a chassis with its modules taking cooling air from a warm aisle, the switch can
over heat 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.
Figure 1-18 shows a blank
power supply filler panel.

Platform Chassis
For power supply specifications, see the “Power Specifications” section on page B-1 . To replace a power
supply, see the “Removing and Installing Power Supplies” section on page 4-16 . For LED descriptions,
see Table E-1 on page E-2 .
Fan Trays
The Cisco Nexus 2248TP-E FEX has one fan tray that is hot swappable during operations. Depending
on the arrangement of hot and cold aisles in your data center, you can order port-side exhaust airflow to
position the fan side of the FEX chassis in a cold aisle or port-side intake airflow to position the back of
the FEX chassis in a cold aisle.
Table 1-4 lists the part numbers for each of the fan trays that you can use
with the Cisco Nexus 2248TP-E chassis.
