Cisco Nexus 2224TP FEX
Fan Tray for the Cisco Nexus 2224TP 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 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 FEX” section on
page 2-14 and the fan tray specifications in AppendixB, “Technical Specifications”. For LED
descriptions, see Appendix E, “LEDs”.
Transceivers and Connectors Supported by the Cisco Nexus 2224TP FEX
The Cisco Nexus 2224TP FEX supports SFP+ Ethernet optical and copper transceivers and optical FEX
Transceivers (FETs) for up to four fabric uplink connections to Cisco Nexus 7000 Series switches, and
it supports 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 2 -2 lists the transceivers supported by this FEX for its
uplink fabric.
Figure 2-10 on page2-10 shows the SFP+ optical transceiver used for uplink connections.
Figure 2-11 on page 2-11 identifies the major features of the SFP+ copper transceiver and cable used for
uplink connections.
Figure 2-12 on page2-11 identifies the major features of RJ-45 connectors, which are used for the
downlink connections.
