Figure 2-15.
Figure 2-15 Port Numbering on the Cisco Nexus 2248TP FEX
Note For a fully dedicated 10-Gbps bandwidth through a M1 Series 32-port 10-Gigabit Ethernet I/O module
(either the N7K-M132XP-12 or N7K-M132XP-12L), connect each FEX to one port in a set of four
shared ports on the module (you connect each set of shared ports to one FEX). If you are using the M2
Series 24-port, 10-Gigabit Ethernet I/O module (N7K-M224XP-23L), you can connect the FEX to any
of its ports for a fully dedicated bandwidth. If you are using the F2 Series 48-port, 10-Gigabit Ethernet
I/O module (N7K-F248XP-25), use the connectivity rule order (connect the same port numbers for each
port group (for example, if you connect ports 1 and 2 of a port-group, then connect the same ports of
another port group).
For information about the transceivers and connectors that you can use with these ports, see the
“Transceivers and Connectors Supported by the Cisco Nexus 2248TP FEX” section on page 2-14.
Power Supplies for the Cisco Nexus 2248TP FEX
The Cisco Nexus 2200 Platform FEX chassis have two slots for front-end AC or DC power supplies that
have front-to-back or back-to-front airflow. These chassis are fully functional with one power supply,
but you can install a second power supply for power redundancy. You can install any of the following
power supplies in those two bays:
• AC power supply with front-to-back airflow (N2200-PAC-400W)
• AC power supply with back-to-front airflow (N2200-PAC-400W-B)
