2.4.1 1000BASE-T Ports
The LPB5028A switch has (20) 1000BASE-T RJ-45 ports and (4) copper/fiber combo ports with dual-speed SFP slots, and the
LPB5052A switch has (48) 1000BASE-T RJ-45 ports. All RJ-45 ports support automatic MDI/MDI-X operation, auto-negotiation
and IEEE 802.3x auto-negotiation of flow control, so the optimum data rate and transmission can be selected automatically.
2.4.2 SFP Transceiver Slots
The Gigabit PoE+ Ethernet Managed Switch Eco LPB5028A supports the Small Form Factor Pluggable (SFP) transceiver slots on
ports 21 to 28, and the LPB5052A supports SFP on ports 48 to 52.
Table 2-1 shows a list of transceiver types that have been tested with the switch. For information on the recommended standards
for fiber optic cabling, see “1000 Mbps Gigabit Ethernet Collision Domain” on page X.
