Supports 10GBASE-SR SFP+, 10GBASE-LR SFP+, 10GBASE-LRM SFP+, 1000BASE-T SFP, 1000BASE-
SX SFP, and 1000BASE-LX SFP pluggable optical transceiver modules.
Dual-personality ports
Port 17 consists of a CX4 port shared with an SFP+ port. Only one may be active. The SFP+
port takes precedence: if it contains a module, it is the active port and the CX4 port is inactive.
Ports 23 and 24 are each shared with inter-switch link ports on the blade switch's backplane.
Either the SFP+ port on the front panel or the backplane port can be active, but both can not
be active at the same time. The SFP+ port on the frontplane takes precedence: if it contains a
module, it is the active port and its corresponding backplane port is inactive.
The ISL ports are disabled in the default configuration on the 6120/XG. When the port is changed
from ISL to transceiver or from transceiver to ISL the port is disabled. The port must be
manually enabled by way of a switch configuration interface and the OA interface before the
ports will link. Do not attempt to enable these ports unless the interconnect blade adjacent to
this switch is an identical ProCurve switch. For more information see the HP BladeSystem OA
User Guide on the HP Web site www.hp.com/go/bladesystem/documentation.
Note To prevent loops, LACP is on by default on these two ports, and Spanning Tree is on by default
for the whole switch.
