Switch Ports
The Dell Networking N3024/N3024P front panel provides 24 Gigabit
Ethernet (10/100/1000BASE-T) RJ-45 ports that support auto-negotiation for
speed, flow control, and duplex. The Dell Networking N3024P models
support two SFP+ 10G ports. Dell-qualified SFP+ transceivers are sold
separately. The Dell Networking N3000 Series switches operate in full-duplex
mode only.
The Dell Networking N3024F front panel provides 24 Gigabit Ethernet
100BASE-FX/1000BASE-X SFP ports plus 2 1000BASE-T combo ports. Dell-
qualified SFP transceivers are sold separately. 1000BASE-T operation requires
the use of auto-negotiation.
The Dell Networking N3048/N3048P front panel provides 48 Gigabit
Ethernet (10BASE-T, 100BASE-TX, 1000BASE-T) RJ-45 ports that support
auto-negotiation for speed, flow control, and duplex. The Dell Networking
N3048/N3048P supports two SFP+ 10G ports. Dell-qualified SFP+
transceivers are sold separately.
The front-panel switch ports have the following characteristics:
The switch automatically detects the difference between crossed and
straight-through cables on RJ-45 ports and automatically chooses the MDI
or MDIX configuration to match the other end.
SFP+ ports support Dell-qualified transceivers. The default behavior is to
log a message and generate an SNMP trap on insertion or removal of an
optic that is not qualified by Dell. The message and trap can be suppressed
by using the
service unsupported-transceiver
command.
RJ-45 ports support full-duplex mode 10/100/1000 Mbps speeds on
standard Category 5 UTP cable.
SFP+ ports support SFP+ transceivers and SFP+ copper twin-ax
technology operating at 10G/1G speeds in full-duplex mode. SFP
transceivers are supported in SFP+ ports and operate at 1G full-duplex.
SFP transceivers require auto-negotiation to be enabled.
The Dell Networking N3024P/N3048P front-panel ports support PoE
(15.4W) and PoE+ (34.2W) as well as legacy capacitive detection for pre-
standard PDs.
Additionally, ports 1–12 support UPOE (60W) power when configured in
high-power mode.
