The base switch and upgrades are as follows:
49Y4294 is the part number for the base switch, and it comes with 14 internal 1 GbE ports enabled,
one to each compute node and ten external 1 GbE ports enabled. All external 1 GbE ports have
RJ-45 connectors.
90Y3562 (Upgrade 1) can be applied on the base switch to take full advantage of four-port adapter
cards installed in each compute node. This upgrade enables 14 additional internal ports, for a total of
28 ports (two ports to each node). The upgrade also enables 10 additional external 1 GbE ports for a
total of twenty 1 GbE external RJ-45 ports. This upgrade requires the base switch.
49Y4298 (10Gb Uplinks) can be applied on the base switch when you need more external bandwidth.
The upgrade enables four external 10 GbE ports with SFP+ connectors (SFP+ transceivers or DAC
cables are not included). This upgrade requires the base switch.
Both 90Y3562 (Upgrade 1) and 49Y4298 (10Gb Uplinks) can be applied on the switch at the same
time to allow you to use 28 internal 10 GbE ports leveraging all four ports on an four-port expansion
card, and to utilize all external ports on the switch.
Flexible port mapping: With Networking OS version 7.8 or later clients have more flexibility in assigning
ports that they have licensed on the EN2092 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 1 GbE ports or
trading off ten 1 GbE ports for the use of an external 10 GbE port (or vice versa). This is very valuable
when you consider the flexibility with the base license and with 10Gb Uplinks upgrade.
With flexible port mapping, clients have licenses for a specific number of ports:
49Y4294 is the part number for the base switch, and it provides 24x 1 GbE port licenses that can
enable any combination of internal and external 1 GbE ports and external 10 GbE ports (with the use
of ten 1 GbE port licenses per one 10 GbE port).
90Y3562 (Upgrade 1) upgrades the base switch by activation of 14 internal 1 GbE ports and ten
external 1 GbE ports which is equivalent to adding 24 more 1 GbE port licenses for a total of 48x 1
GbE port licenses. Any combination of internal and external 1 GbE ports and external 10 GbE ports
(with the use of ten 1 GbE port licenses per one 10 GbE port) can be enabled with this upgrade. This
upgrade requires the base switch.
49Y4298 (10Gb Uplinks) upgrades the base switch by activation of four external 10 GbE ports for a
total of 24x 1 GbE ports and 4x 10 GbE ports. With the use of one external 10 GbE port license for ten
1 GbE ports, any combination of internal and external 1 GbE ports and external 10 GbE ports can be
enabled with this upgrade. This upgrade requires the base switch.
Both 90Y3562 (Upgrade 1) and 49Y4298 (10Gb Uplinks) simply activate all the ports on the EN2092
which is 28 internal 1 GbE ports, 20 external 1 GbE ports, and four external 10 GbE SFP+ ports.
Note: When both Upgrade 1 and 10Gb Uplinks are activated, flexible port mapping is no longer used
because all the ports on the EN2092 are enabled.
