Dual INB Modules
Dual INB Modules make use of both INB 1 and
INB 2 backplanes. When a Dual INB board is
inserted into the backplane, the chassis makes a
determination as to which backplane it will attach
to. This is done by checking the loads on both
INBs and the INB with the least amount of traffic
will be the one the board communicates with. The
speed at which the backplane is running will
depend upon the speed of the slowest board.
The following devices of Dual INB Modules are
supported:
• The 9H531-17 is a high-performance Fast
Ethernet module for the SmartSwitch 9000,
providing 16 100Base-FX ports via MTRJ
interfaces, and one VHSIM interface that can
support ATM, Gigabit Ethernet, FDDI and
WAN connectivity.
• The 9H531-18 is a high-performance Fast
Ethernet module for the SmartSwitch 9000,
providing 16 100Base-FX ports via MTRJ
interfaces. In addition, the 9H532-18’s GPIM
slot can also be populated with a variety of
media types, including switched 1000Base-
SX/LX Gigabit Ethernet.
• 9H531-24 is a high-performance Fast
Ethernet module for the SmartSwitch
9000,providing 24 100Base-Fx ports via
MTRJ interfaces.
• The 9H532-17 is a high-performance Fast
Ethernet module for the SmartSwitch 9000,
providing 16 auto-negotiating 10/100Base-TX
ports via RJ45 interfaces. In addition, a
VHSIM interface can support ATM, Gigabit
Ethernet, FDDI and WAN connectivity.
• The 9H532-18 is a high-performance Fast
Ethernet module for the SmartSwitch 9000,
providing 16 auto-negotiating 10/100Base-TX
ports via RJ45 interfaces. In addition, the
9H532-18’s GPIM slot can also be populated
with a variety of media types, including
switched 1000Base-SX/LX Gigabit Ethernet.
