Introducing the Switches |11
Management ports
You can connect the switch to a PC running Microsoft Windows or to a terminal server through either the RJ-
45 console port or the USB-C console port. These ports use the following connectors:
nRJ-45 console port uses a console connection with these pinout assignments:
RJ-45 (Signal reference from chassis)
Reserved 1 CTS
Reserved 2 DSR
TXD 3 RXD
Reserved 4 DCD
GND 5 GND
RXD 6 TXD
Reserved 7 DTR
Reserved 8 RTS
nUSB-C console port
To use the USB-C console port, you must install the Windows USB device driver on the device that is connected to
the USB-mini console port and that is running Microsoft Windows. With the Windows USB device driver,
connecting and disconnecting the USB cable from the console port does not affect Windows HyperTerminal
operations. Mac OS X or Linux require no special drivers.
Only the connected and active port will be able to input data. For information on using the CLI to configure
the USB-C interface, see the switch software guide.
Different configurations are available. Not all ports are present in all configurations.
100/1000 SFP/10G SFP+ Ports (Uplink)

Aruba 4100i Switch Series | Installation and Getting Started Guide 12
Depending on the switch model, the uplink ports support 100Mbps FX, 1G or 10G optics (no support for
10G LRM optics).
For more information on SFP/SFP+, see the Transceiver Guide.
10/100/1000 BASE-T Ports (Downlink)
You can set the 10/100/1000 Base-T ports to operate in 10 or 100 Mbp/s in full-duplex or half-duplex
mode. You can also set these ports for speed and duplex autonegotiation in compliance with IEEE 802.3.
(The default setting is autonegotiate.) When set for autonegotiation, the port receives the speed and duplex
settings of the attached device and advertises its own capabilities. If the connected device also supports
autonegotiation, the switch port negotiates the best connection (that is, the fastest line speed that both
devices support, and full-duplex transmission if the attached device supports it) and configures itself
accordingly. In all cases, the attached device must be within 328 feet (100 meters). 100BASE-TX traffic
requires Category 5 cable. 10BaseT traffic can use Category 3 or Category 4 cables.
Console Ports
Aruba 4100i switches include an RJ-45 serial console port on the front of the switch. This port is used to
connect a console to the switch by using an RJ-45 serial cable (not supplied). A DB9-to-RJ-45 console cable
can be ordered from HPE: JL448A, Aruba X2C2 RJ45 to DB9 Console Cable.
The switch also has a USB-C console port on the front of the switch. The USB-C has precedence for input. If
both cables are plugged in, the console output is echoed to both the RJ-45 and the USB-C, but the input is
only accepted from the USB-C.
JL817A
JL818A

Introducing the Switches |13
nUse of the USB-C port may require the installation of a standard USB driver. New Windows installs include
the driver by default.
The console can be a PC or workstation running a VT-100 terminal emulator, or a VT-100 terminal.
The Aruba CX mobile app and the Aruba USB Bluetooth adapter enable you to configure your switch from
your mobile device. For information about using the Aruba CX mobile app to configure the switch, see the
Fundamentals Guide for your switch and software release.
DC Power connectors
(JL817A only)
DC connection is supported for the JL817A through two connectors on the front panel of the switch. The
dual-feed power supply provides primary and secondary DC power (DC-1 and DC-2). The switch is capable
of operating with a single or dual power source. When using both power sources, the switch will draw power
from the DC source with the higher voltage. Each of the power sources serve as redundancy to one another.
The switch has an ORing controller to provide protection against reverse-polarity conditions but does NOT
support summation of power for capacity when combining both power supplies together.

Aruba 4100i Switch Series | Installation and Getting Started Guide 14
For safe and reliable DC connection, use wiring that is 14 AWG, up to 2 meters.
Ensure that the wires are secured by tightening the captive screws.
Alarm connector
JL817A

Introducing the Switches |15
JL818A
Alarm signals can be connected to the switch through the alarm connector. The switch supports two alarm
inputs and one alarm output relay. The alarm connector provides six alarm wire connections.

INGND Alarm input reference ground
IN1 Alarm input 1
Alarms can be configured in the CLI. Each alarm input can be configured as normally open or normally
closed contact and can be used for environmental, power supply or port needs. The alarm output can be
connected to an external device such as a light or bell.

Introducing the Switches |17
Configuring alarm relays
Industrial rugged switches have hardware alarm ports that generate an alarm on internal or external
condition depending on alarm port wiring during system installation. The switch provides for 1x output
alarm port that could be wired to an external device. When an external device like an external alarm bell is
wired to the output port, configuring the event to output relay will trigger the bell to ring indicating the
event. These events could also be configured to send syslog messages and SNMP traps. The switch also
provides for 2x input alarm ports. An external device like a door or a sensor could be connected to the
switch which can be configured to trigger a syslog or SNMP. These could also be forwarded to the relay
circuit at the alarm output port.
To configure the alarm relays, refer to the following CLI commands. For additional CLI and
software information, see the Monitoring Guide for your switch.
Alarm commands
