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).

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.
