130 Hardware Overview
The Dell EMC Networking N2024P/N2048P front panel has status LEDs for
over-temperature alarm, internal power and status on the top row. The
bottom row of status LEDs displays the management unit in the stack,
modular power supply (MPS), status and fan alarm status.
Switch Ports
The Dell EMC Networking N2024/N2024P 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 EMC Networking N2024/N2024P
models support two SFP+ 10G ports. Dell EMC-qualified SFP+ transceivers
are sold separately. Dell EMC Networking N2000 Series switches operate in
full-duplex mode only.
The Dell EMC Networking N2048/N2048P 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 EMC
Networking N2048/N2048P supports two SFP+ 10G ports. Dell EMC-
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 EMC-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. 1000BASE-T operation requires the use of
auto-negotiation.
• SFP+ ports support SFP+ transceivers and SFP+ copper twin-ax
technology operating at 10G or 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 EMC Networking N2024P/N2048P front-panel ports support
PoE (15.4W) and PoE+ (34.2W) as well as legacy capacitive detection for
pre-standard powered devices (PDs).
