Figure 3-3. N2024P Close-up
The N2024P front panel, shown in Figure3-3, has status LEDs for over-
temperature alarm, internal power and status on the top row. The bottom row
of status LEDs displays stack master, modular power supply ( MPS) status and
fan alarm status.
Switch Ports
The 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 N2024/N2024P models support two SFP+ 10G
ports. Dell-qualified SFP+ transceivers are sold separately.
The 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 N2048/N2048P support two SFP+ 10G
ports. Dell-qualified SFP+ transceivers are sold separately.
The front-panel switch ports have the following characteristics:
• The sw itch 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.
