IBM Ethernet Switch B24X 10
Table 5 lists the methods that the B24X can use to connect to another device.
Table 5. Connectivity options
On the B24X On the device to be connected
SFP+ port using 10 GbE SFP+ optical
transceiver: 69Y0389: 10GBASE-SR
This 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 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 B24X within the proper wavelength and power
specifications.
Multi-mode or single-mode fiber as specified
required for connectivity. See the "Network cabling
requirements" section.
SFP+ port using 10 GbE Direct Attach
SFP+ Active TwinAx cable:
45W2398 or 45W2401: 1 meter
z
45W2408 or 45W2409: 3 meter
z
45W3039 or 45W3042: 5 meter

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 B24X.
Below is a list of IBM server adapters that have
been tested for compatibility with the part numbers
in the left-hand column. If a product is not listed,
that does not necessarily mean that it is
incompatible--it simply has not been tested.

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.
Connectivity to IBM System servers
The B24X can be deployed as a Top of Rack 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. Additional 1 GbE NICs
can be installed to increase connectivity. These NICs might have RJ-45 ports, SFP ports requiring a
transceiver, or integrated optical transceivers. Follow the guidelines in Table 5 for connectivity.
