System compatibility

Summit X450a-48tDC works with XGM2 series dual 10G SFP+ uplink expansion cards. It supports SummitStack stacking for multi-switch cluster deployment. Compatible with Extreme original 1G SFP transceivers installed on combo SFP slots. Supports Layer2 switching and Layer3 IP routing, suitable for telecom equipment room and industrial sites with -48V DC power supply.

Function

Summit X450a-48tDC is a 1U rack-mounted DC-powered high-density gigabit switch. It provides 44 fixed RJ45 gigabit ports plus four combo ports for flexible copper or fiber access. The rear expansion slot can add dual 10G SFP+ uplink ports to connect core network. It supports stacking, advanced QoS, VLAN segmentation and ACL security filtering, widely used in telecom, campus aggregation and industrial network.

Installation

Mount the switch into standard 19-inch equipment rack. Connect -48V DC power cable. Use RJ45 console cable for initial configuration. Insert 1G SFP transceivers into combo SFP slots and connect fiber patch cords. Install XGM2 uplink card on rear slot after power-off if 10G uplink is required. Configure stacking parameters via ExtremeXOS CLI for multi-switch stack.
