To see the components that you use when installing a power supply unit, see
Figure 1-12 on page 1-12
for the AC power supply with front-to-back airflow,
Figure 1-13 on page 1-13
for the AC power supply
with back-to-front airflow, and
Figure 1-14 on page 1-13
for the DC power supply with front-to-back
airflow.
You can order the Cisco Nexus 2224TP FEX with AC power supplies that have front-to-back or
back-to-front airflow for cooling or DC power supplies that have 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 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
reach an overtemperature 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 to cover the empty slot.
Figure 1-15 on page 1-14
shows a blank power supply filler
panel.
For power supply specifications, see
Table B-1 on page B-2
. To replace a power supply, see the
“Removing and Installing Power Supplies” section on page 3-17
.
Fan Tray
The Cisco Nexus 2224TP FEX has one fan tray that is hot swappable during operations. Depending on
whether there is a cold aisle in front of or in back of the chassis, you can order front-to-back airflow or
back-to-front airflow for the fan tray and the power supplies in the same chassis.
Table 1-18
lists the part
numbers for each of the fan trays that you can use with this chassis.
To see the components used when installing one of these fan trays, see
Figure 1-16
(front-to-back
airflow) or
Figure 1-17
(back-to-front airflow).
