NOTE
If you are adding PowerConnect B-Series FCX-E or PowerConnect B-Series FCX-I devices to a stack
containing PowerConnect B-Series FCX-S devices, you must reconfigure the stacking ports on the
PowerConnect B-Series FCX-S devices to be the 10 Gbps ports on the front panel. You can then
connect all of the devices in a stack using front panel ports.
Changing PowerConnect B-Series FCX-S and CX4 ports from 16 Gbps to 10 Gbps
You can configure the 16 Gbps PowerConnect B-Series FCX4 ports to operate as 10 Gbps ports
using the speed-duplex command, as shown in the following example.
Syntax: speed-duplex [10-full | 10-half | 100-full | 100-half | 1000-full-master | 1000-full-slave
|10g-full | auto]
• 10-full - 10M, full duplex
• 10-half - 10M, half duplex
• 100-full - 100M, full duplex
• 100-half - 100M, half duplex
• 1000-full-master - 1G, full duplex, master
• 1000-full-slave - 1G, full duplex, slave
• 10g-full - 10G, full duplex
• auto - Autonegotiation
NOTE
Both ends of a link must be configured for 10 Gbps for the link to operate as 10 Gbps. If you want
the link to operate as a 16 Gbps link, both ends of the link must be configured for 16 Gbps.
