LPB2810A Quick Start Guide
Chapter 2: Overview
2.3 Description of Hardware
• 1000BASE-T Ports: The switch contains (8), (20), or (44) 1000BASE-T RJ-45 ports. All RJ-45 ports support automatic MDI/
MDI-X operation, autonegotiation, and IEEE 802.3x autonegotiation of flow control, so the optimum data rate and transmission
can be selected automatically.
• SFP Transceiver Slots: The LBG1108A 10-Port PoE+ Gigabit Managed Switch Eco supports the small form-factor pluggable (SFP) transceiver
slots, which are shared with RJ-45 Port 9 and 10. In the default configuration, if an SFP transceiver (purchased separately) is installed in a slot
and has a valid link on the port, the associated RJ-45 port is disabled. The LPB2826A 26-Port PoE+ Gigabit Managed Switch Eco also sup-
ports the small form-factor pluggable (SFP) transceiver slots, which are shared with RJ-45 Ports 21–24, and (2) additional SFP ports. The
LPB2848A 48-Port PoE+ Gigabit Managed Switch Eco has (4) dual-media UTP/SFP ports (Ports 45–48).
The following table shows a list of transceiver types that have been tested with the switch. For an updated list of vendors supplying these
transceivers, contact your local dealer. For information on the recommended standards for fiber optic cabling, see “1000-Mbps Gigabit
Ethernet Collision Domain” in Section 5.2, Tables 5-1 through 5-4, or contact Tech Support at 724-746-5500.
