N3K-C3048-FAN is the fan module for the Cisco Nexus 3048 switch with forward airflow, meaning port-side exhaust. Its spare form is N3K-C3048-FAN=, and the reversed-airflow (port-side intake) version is N3K-C3048-FAN-B, with the spare form N3K-C3048-FAN-B=.
The Nexus 3048 uses one fan tray with redundant fans. The tray is hot swappable, but it must be swapped within 1 minute. A chassis with forward-airflow fans takes forward-airflow power supplies: N2200-PAC-400W for AC (100 to 240 VAC) or N2200-PDC-400W for DC (-40 to -72 VDC, 33 A maximum). The reversed-airflow counterparts are N2200-PAC-400W-B and N3K-PDC-350W-B. The 3048 takes two redundant power supplies.
The switch that this fan module cools has 48 x 10/100/1000 Mbps RJ-45 ports and 4 x 1/10 Gbps SFP+ uplink ports. It adds two 10/100/1000 management ports, of which only one is enabled and active, plus an RS-232 console port and a USB port. Switching capacity is 176 Gbps and the forwarding rate is 132 Mpps.
The Nexus 3048 chassis measures 1.72 x 17.3 x 19.7 in (4.4 x 43.9 x 50.5 cm) and weighs 20.5 lb (9.3 kg). A live N2200-PAC-400W forward-airflow supply matches this fan module.
