NOTE:
SIO1 (Stacking Input/Output 1) and SIO2 are logical stacking port pairs. A logical stacking port
pair must always be connected to the same Switch in the stack. Splitting logical stacking port
pairs between different Switches in the stack might not guarantee a stable stacking connection.
Switch to Switch
The Switch can be used to connect to any other switch or hub in the network. This network topology is used when the
Switch does not have enough ports to cater for all the end nodes in the network.
There is a great deal of flexibility on how connections are made using the appropriate cabling.
•
Connect a 10BASE-T or 100BASE-TX switch port to the Switch using a Category 3/4/5 UTP/STP cable.
•
Connect a 1000BASE-T switch port to the Switch via a Category 5e UTP/STP cable.
•
Connect a 2.5GBASE-T switch port to the Switch via a Category 5e/6 UTP/STP cable.
•
Connect a 10GBASE-T switch port to the Switch via a Category 6a UTP/STP cable.
•
Connect a fiber uplink switch port to the Switch's SFP+ port via a fiber optical cable.
