mode. All four SFP28 ports must be configured to operate at the same
speed. 25GBASE-CR and 10G-BASE-CR modes (copper twin-ax or DAC
cables) require the use of auto-negotiation.
• The default behavior is to log a message and generate an SNMP trap on
insertion or removal of a transceiver that is not qualified by Dell. The
message and trap can be suppressed by using the service unsupported-
transceiver command.
On the N2224X-ON/N2224PX-ON switches, ports 1-12 may be configured to
support 10M/100M half-duplex.
On the N2248X-ON switches, ports 5-36 may be configured to support
10M/100M half-duplex.
N2200-ON SFP28 ports may be configured to operate using SFP+
transceivers using the speed 10000 command for fiber media or the speed
auto 10000 command for copper media. All four SFP28 ports must be
configured to operate at the same speed. A mix of SFP+ and SFP28
transceivers or speeds is not supported. The switch UI does not enforce this
restriction.
N2200-ON Series Console Port
The console port provides serial communication capabilities, which allows
communication using RS-232 protocol. The serial port provides a direct
connection to the switch and allows access to the CLI from a console
terminal connected to the port through the provided serial cable (with RJ-45
YOST to female DB-9 connectors). The console port is separately
configurable and can be run as an asynchronous link from 1200 baud to
115,200 baud. The Dell CLI only supports changing the speed. The defaults
are 115,200 baud rate, 8 data bits, no parity, 1 stop bit, no flow control.
