Planning the cabling scheme Use SFP+ cables or SFP+ transceiver modules and fibers to connect the IRF member switches. • SFP+ cables-Reliable and suitable for IRF connection over a relatively short distance. • SFP+ transceiver modules and fibers-More flexible and suitable for IRF connection over a long distance. Table 9 and Table 10 list the SFP+ transceivers and SFP+ cables available for the HP 6125 blade switch IRF connections. Configuring basic IRF settings After you install the IRF member blade switches, power on the blade switches, and log in to each IRF member blade switch (see HP 6125 Blade Switch Series Fundamentals Configuration Guide) to configure their member IDs, member priorities, and IRF port bindings. For more information about configuring basic IRF settings, see HP 6125 Blade Switch Series IRF Configuration Guide. Connecting the physical IRF ports Use SFP+ cables or SFP+ transceiver modules and fibers to connect the IRF member switches as planned. NOTE: Wear an ESD-preventive wrist strap when you connect SFP+ cables or SFP+ transceiver modules and fibers. For how to connect them, see Pluggable SFP[SFP+][XFP] Transceiver Modules Installation Guide. Accessing the IRF fabric to verify the configuration To verify the basic functionality of the IRF fabric after you finish configuring basic IRF settings and connecting IRF port: 1. Log in to the IRF fabric through the console port of any member switch. 2. Create a Layer 3 interface, assign it an IP address, and make sure that the IRF fabric and the remote network management station can reach each other. 3. Use Telnet, web, or SNMP to access the IRF fabric from the network management station. (See HP 6125 Blade Switch Series Fundamentals Configuration Guide.) 4. Check that you can manage all member switches as if they were one node. 5. Display the running status of the IRF fabric by using the commands in Table 4.

Planning the cabling scheme
Use SFP+ cables or SFP+ transceiver modules and fibers to connect the IRF member switches.
•
SFP+ cables
—Reliable and suitable for IRF connection over a relatively short distance.
•
SFP+ transceiver modules and fibers
—More flexible and suitable for IRF connection over a long
distance.
Table 9
and
Table 10
list the SFP+ transceivers and SFP+ cables available for the HP 6125 blade switch
IRF connections.
Configuring basic IRF settings
After you install the IRF member blade switches, power on the blade switches, and log in to each IRF
member blade switch (see
HP 6125 Blade Switch Series Fundamentals Configuration Guide
) to configure
their member IDs, member priorities, and IRF port bindings.
For more information about configuring basic IRF settings, see
HP 6125 Blade Switch Series IRF
Configuration Guide
.
Connecting the physical IRF ports
Use SFP+ cables or SFP+ transceiver modules and fibers to connect the IRF member switches as planned.
NOTE:
Wear an ESD-preventive wrist strap when you connect SFP+ cables or SFP+ transceiver modules and
fibers. For how to connect them, see
Pluggable SFP[SFP+][XFP] Transceiver Modules Installation Guide
.
Accessing the IRF fabric to verify the configuration
To verify the basic functionality of the IRF fabric after you finish configuring basic IRF settings and
connecting IRF port:
1.
Log in to the IRF fabric through the console port of any member switch.
2.
Create a Layer 3 interface, assign it an IP address, and make sure that the IRF fabric and the
remote network management station can reach each other.
3.
Use Telnet, web, or SNMP to access the IRF fabric from the network management station. (See
HP
6125 Blade Switch Series Fundamentals Configuration Guide
.)
4.
Check that you can manage all member switches as if they were one node.
5.
