You can expand your 10Base-T or 100Base-TX or 1000Base-SX/LX/T networks beyond its hub limit by adding a 4-Slot Modular Switch.
10Base-T Networks
10Base-T Networks are limited to four hubs between any two nodes. By adding your 4-Slot Modular Switch to a network, you can divide that network into segments with their own collision domains. In other words, you can connect one 10Base-T network with four hubs to your
4-Slot Modular Switch. Then you can connect another 10Base-T network with four hubs to your 4-Slot Modular Switch. You will then have one network with two collision domains, allowing four hubs on each port.

100Base-TX Networks
The hub limit of a 100Base-TX network depends on the class of the hub in the network. With a Class I hub, the network is limited to one hub. With a Class II hub, the network is limited to two hubs.
However, you can expand your 100Base-TX network that includes either class of hub by adding a 4-Slot Modular Switch. With the 4-Slot Modular Switch added to your 100Base-TX network, you can separate that network into individual segments with their own collision domains. In other words, you can connect one 100Base-T network with one or two hubs to the 4-Slot Modular Switch, and you can connect another 100Base-TX network with one or two hubs to the 4-Slot Modular Switch. You will then have one network with two collision domains.
