The N2K-C2148T-1GE is a Cisco Nexus 2148T 1GE fabric extender with 48 host ports and 4 fabric ports. The host ports are 1000BASE-T with RJ-45 connectors, and the four 10 Gigabit Ethernet fabric ports take SFP+ transceivers. The unit has one fan module, and an HDMI port is provided for management connection.
Fabric speed is 40 Gbps in each direction (80 Gbps full duplex) with 1.2:1 oversubscription. Hardware forwarding runs at 176 Gbps or 131 million packets per second, with 4 hardware queues per port. Fabric links use SFP-10G-SR, SFP-10G-SR-S, SFP-10G-LR or SFP-10G-LR-S optics, passive Twinax cables SFP-H10GB-CU1M, SFP-H10GB-CU3M and SFP-H10GB-CU5M, or active Twinax cables SFP-H10GB-ACU7M and SFP-H10GB-ACU10M. The distance to a Cisco Nexus 5000 Series switch is up to 3 km.
The parent switch is a Cisco Nexus 5000 Series switch, with a minimum NX-OS release of 4.0(1A)N2(1). The chassis measures 1.72 x 17.3 x 20.0 in. (4.37 x 43.94 x 50.8 cm) and weighs 18 lb (8.2 kg) fully loaded. Typical input power is 150 W (165 W maximum), and heat dissipation is 670 BTU per hour.
The power supply is the N2K-PAC-200W and the fan tray is the N2K-C2148-FAN. The Nexus 2200 400W power supplies and 2200 fans do not fit this model. Nexus fabric extenders and related parts can be found in Cisco switches.
