Lenovo Flex System Fabric CN4093 Product Manual page 3

Flexible port mapping: With Networking OS version 7.8 or later clients have more flexibility in assigning
ports that they have licensed on the CN4093 which can help eliminate or postpone the need to purchase
upgrades. While the base model and upgrades still activate specific ports, flexible port mapping provides
clients with the capability of reassigning ports as needed by moving internal and external 10 GbE ports and
Omni Ports, or trading off four 10 GbE ports for the use of an external 40 GbE port. This is very valuable
when you consider the flexibility with the base license and with Upgrade 1 or Upgrade 2.
Note: Flexible port mapping is not available in Stacking mode.
With flexible port mapping, clients have licenses for a specific number of ports:
00D5823 is the part number for the base switch, and it provides 22x 10 GbE port licenses that can
enable any combination of internal and external 10 GbE ports and Omni Ports and external 40 GbE
ports (with the use of four 10 GbE port licenses per one 40 GbE port).
00D5845 (Upgrade 1) upgrades the base switch by activation of 14 internal 10 GbE ports and two
external 40 GbE ports which is equivalent to adding 22 more 10 GbE port licenses for a total of 44x 10
GbE port licenses. Any combination of internal and external 10 GbE ports and Omni Ports and
external 40 GbE ports (with the use of four 10 GbE port licenses per one 40 GbE port) can be enabled
with this upgrade. This upgrade requires the base switch.
00D5847 (Upgrade 2) upgrades the base switch by activation of 14 internal 10 GbE ports and six
external Omni Ports which is equivalent to adding 20 more 10 GbE port licenses for a total of 42x 10
GbE port licenses. Any combination of internal and external 10 GbE ports and Omni Ports and
external 40 GbE ports (with the use of four 10 GbE port licenses per one 40 GbE port) can be enabled
with this upgrade. This upgrade requires the base switch.
Both 00D5845 (Upgrade 1) and 00D5847 (Upgrade 2) simply activate all the ports on the CN4093
which is 42 internal 10 GbE ports, two external SFP+ ports, 12 external Omni Ports and two external
QSFP+ ports.
Note: When both Upgrade 1 and Upgrade 2 are activated, flexible port mapping is no longer used because
all the ports on the CN4093 are enabled.
Table 2 lists supported port combinations on the switch and required upgrades.
