Cisco Nexus 2248TP FEX
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 page3-13.
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 port-side-exhaust or port-side-intake 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 port-side-exhaust airflow (N2200-PAC-400W)
•AC power supply with port-side-intake airflow (N2200-PAC-400W-B)
•DC power supply with port-side-exhaust airflow (N2200-PDC-400W)
•DC power supply with port-side-intake airflow (N2200-PDC-350W-B)
Caution Make sure that all of the fan tray and power supply modules use the same airflow direction and have the
same color designation on the front. Otherwise, the switch can over heat and shut down,
For information on these power supplies, see the “Power Supplies for the Cisco Nexus 2248TP FEX”
section on page 3-13 and the power supply specifications in the Appendix B, “Technical Specifications”.
Fan Tray for the Cisco Nexus 2248TP FEX
The Cisco Nexus 2224TP, 2248TP, and 2248TP-E FEXs use the same fan tray that you can order with
either port-side-exhaust airflow (N2K-C2248-FAN) or port-side-intake airflow (N2K-C2248-FAN-B).
Caution Make sure that all of the fan tray and power supply modules use the same airflow direction and have the
same color designation on the front. Otherwise, the switch can over heat and shut down,
For information on this fan tray, see the “Fan Tray for the Cisco Nexus 2248TP-E FEX” section on
page 3-6 and the fan tray specifications in Appendix B, “Technical Specifications”. For LED
descriptions, see Appendix E, “LEDs”.
Transceivers and Connectors Supported by the Cisco Nexus 2248TP FEX
The Cisco Nexus 2248TP FEX supports SFP+ Ethernet copper and optical transceivers for up to four
fabric uplink connections to Cisco Nexus 9396PX switches, and it supports 100/1000BASE-T RJ-45
connectors for up to 48 downlink connections to hosts. For each uplink cable, you must use the same
transceiver on both ends. Table 3 -2 lists the transceivers supported by this FEX for its uplink fabric.
