Cisco Nexus 2248TP FEX
• DC power supply with front-to-back airflow (N2200-PDC-400W)
• DC power supply with back-to-front airflow (N2200-PDC-350W-B)
For information on these power supplies, see the “Power Supplies for the Cisco Nexus 2248TP FEX”
section on page 2-13 and the power supply specifications in the “Power Specifications” section on
page B-1. To replace one of these power supplies, see the “Removing and Installing Power Supplies”
section on page 3-17.
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 front-to-back airflow (N2K-C2248-FAN) or back-to-front airflow (N2K-C2248-FAN-B).
For information on this fan tray, see the “Fan Tray for the Cisco Nexus 2248TP-E FEX” section on
page 2-7 and the fan tray specifications in the “Environmental Specifications” section on page B-4 and
the “Physical Specifications” section on page B-5. For LED descriptions, see Table D-1 on page D-2. To
replace one of these fan trays, see the “Removing and Installing the Fan Tray” section on page 3-20.
Transceivers and Connectors Supported by the Cisco Nexus 2248TP FEX
The Cisco Nexus 2248TP 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 page 2-10 shows the SFP+ optical transceiver used for uplink connections. For
specifications that apply to these optical transceivers, see the “SFP+ Optical Transceiver Specifications”
section on page B-6.
