10/100/1000 MbE RJ-45 port
Auto-sensing, auto-negotiating,

auto-MDI/MDIX
Connect to any RJ-45 port or TX adapter supporting 10,
100, or 1000 Mbps Ethernet over CAT5 or higher cabling
up to 100 meters.
On optional 4-port 10 GbE SFP+ interface
module (81Y1455): SFP+ port using 10
GbE SFP+ optical transceiver:

The above optical transceiver receives a
duplex LC connector.
The optic on the device being connected can be another
form-factor (that is, XFP transceiver, X2 module, or
integrated into NIC), but it must have a matching optical
transmission type.
For example, a 10GBASE-SR XFP optical transceiver on
the device being connected must match a 10GBASE-SR
SFP+ optical transceiver on the B48Y within the proper
wavelength and power specifications.
Multi-mode or single-mode fiber as specified required for
connectivity. See the "Network cabling requirements"
section.

Direct Attach Cables (DACs) are copper
cables with two SFP+ transceivers attached
to either end of the cable.
It is up to the user to decide whether the interface on the
device being connected supports the IBM DAC used with
the B48Y.
Below is a list of IBM devices that have been tested for
compatibility with the part numbers in the left-hand
column. If a product is not listed, it does not necessarily
mean that it is incompatible. It simply has not been tested.

Connectivity to IBM System servers
The B48Y can be deployed as a Top of Rack (ToR) access switch to provide connectivity to servers within
a rack. This includes servers from IBM System x, System p, and System i.
IBM System x servers typically come with on-board 1 Gbps Ethernet RJ-45 ports. Typical cabling on the 1
Gbps ports between the switch and the server NIC use Category 5 or higher copper cables with RJ-45
connectors supporting distances of up to 100 meters.
