VH-2402-L3 or to either of the two 100BASE-TX ports on the front-panel module that came preinstalled on the switch. Port 1x can be used as an uplink port to connect to another switch using either a crossed or a straight-through cable. -
Page 41: Switch To Hub Or Switch
If the other switch or hub contains an unused Uplink port, we suggest connecting the other device’s Uplink (MDI-II) port to any of the switch’s (MDI-X) ports (1x - 22x, or one of the 100BASE-TX module ports) using a normal straight-through cable, as shown below. -
Page 42: 10Base-T Device
If the other device does not have an unused Uplink port, make the connection with a normal straight- through cable from the Uplink port on the switch to any normal crossed port on the hub. Alternatively, if you have a crossover cable you can save the Uplink ports for other connections and make this one from a crossed port to another crossed port. -
