Pay As You Grow
The Pay As You Grow (PAYG) software feature allows you to purchase a Z9500 switch with 36 40G ports (144 10G ports) and
upgrade to a larger number of ports as your networking needs grow.
A Z9500 switch with a 36 40G-port license has only the ports on line card 0 enabled. See the Port Numbering figure in this
section for exact port location. You can purchase a license for additional Z9500 port configurations:
● 84 40G ports on line cards 0 and 1 (336 10G ports)
● 132 40G ports on line cards 0, 1, and 2 (528 10G ports)
You can upgrade from a 36 40G-port to either an 84 40G-port or a 132 40G-port configuration. Each license change requires
you to reload the switch to enable the additional ports.
Figure 96. Z9500 Port Numbering
On each line card, the fixed 40G ports are numbered from bottom to top in multiples of four, starting with zero; for example, 0,
4, 8, 12, and so on. When a breakout cable is installed, the resulting four 10G ports are numbered with the remaining numbers.
For example, the 40G port 0 contains 10G ports 0, 1, 2, and 3; the 40G port 4 contains 10G ports 4, 5, 6, and 7.
NOTE: Although unlicensed ports are powered down, they are user-configurable.

Installing a License
The Z9500 supports only perpetual licensing — licenses that are valid for the life of the product and never need to be renewed.
A perpetual license does not expire. It must be bound to only one service tag at a time. For more information about Z9500
licensing, contact your local Dell Networking support team or the Dell Networking Technical Assistance Center.
To install a license on a Z9500 switch:
1. Check the currently installed port license.
