Setting up an IRF fabric 
You can use HP IRF technology to connect and virtualize A5500 EI switches or A5500 SI switches into a 
virtual switch called an “IRF fabric” or “IRF virt ual device” for flattened network topology, and high 
availability, scalabili ty, and manageability. 
An IRF fabric cannot have both A5500 EI and A5500 SI switches.

Step Description
1.  Plan IRF fabric setup  Plan the installation site and IRF fabric setup parameters: 
•
 Planning IRF fabric size and the installation site 
• Identifying the master switch and planning IRF member IDs 
• Planning IRF topology and connections 
• Identifying physical IRF ports on the member switches 
• Planning the cabling scheme  
2.   Install IRF member 
switches  See ”
Installing the switch in a 19-inch rack ” a nd “Mounting the switch on a 
workbench .” 
3.  Connect the...

Planning IRF topology and connections 
You can create an IRF fabric in daisy chain topology,  or more reliably, ring topology. In ring topology, 
the failure of one IRF link does not cause the IRF fabric  to split as in daisy chain topology. Rather, the IRF 
fabric changes to a daisy chain topology  without interrupting network services. 
You connect the IRF member switches through IRF ports.  An IRF port is a logical interface for the internal 
connection between IRF member switches. Each IRF me...

 41 
Identifying physical IRF ports on the member switches  
 IMPORTANT: 
All the switches in a ring topology and the non-edge switches in a daisy chain topology must have at 
least one two-port interface card or two one-port interface cards.  
 
Only the 10-GE ports on the IRF-c apable interface cards listed in “Interface cards” can provide IRF 
conn
ections for the A5500 EI and A5500 SI switches. To use the IRF feature, you must order the cards 
separately.  
Planning the cabling scheme 
When you plan...

Figure 35  Use 2-port interface cards to set up multi-link IRF connection 
 
•   If both of the neighboring switches use 1-port in terface cards, the port on MOD 1 on one switch 
must connect to the port on MOD 2 on the other switch (see callout 1 in  Figure 36).  
•   If one switc

h uses a 1-port interface card but  the other switch uses a 2-port interface card:  
{ If the 1-port interface card is in the MOD 1 slot , the port on the card must connect to the right 
port on the 2-port interface card...

Connecting the physical IRF ports 
Wear an ESD-preventive wrist strap when you connect the physical IR F ports. For how to connect them, 
see Pluggable SFP/SFP+/XFP Transcei ver Modules Installation Guide. 
Connect the IRF member switches as planned in “ Setting up an IRF fabric”.

AC input 
If the system status LED is off, an AC input failure has occurred. Verify the following items: 
•   The AC power cord is securely co nnected to the switch, and the AC-input power receptacle on the 
switch and the connected AC power outlet are in good condition.  
•   The external AC power system is correctly working.  
•   The operating temperature of the switch is in th e normal range, and the power module has good 
ventilation. Over-temperature can cause the power  module to stop working...
