104 Hardware Overview
The N3000 front panel also displays status LEDs for over-temperature alarm,
internal power supply 1 and switch status on the top row. The bottom row of
status LEDs displays stack master, internal power supply 2 and fan alarm.
Switch Ports
The 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 N3024P models support two SFP+ 10G ports.
Dell-qualified SFP+ transceivers are sold separately.
The 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.
The 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 N3048/N3048P support 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 plus SFP transceivers operating at 1G.
• The N3024P/N3048P front panel ports support PoE (15.4W) and PoE+
(34.2W).
