stack must be equipped with a STS-LM Stacker Link Module and an appropriate stacker link cable. The SmartStack STS-8SU External Stacker Unit works as a common backplane switching fabric, which provides 2.2 Gbps of aggregate bandwidth.

➽Note: The SmartStack STS16-20D and the SmartStack STS16-20R can be stacked together with other switches from the STS16-20x family in any desired combination. All switches in a stack must, however, run the same software version.

Optional Redundant Power Supply on

SmartStack STS16-20R

The SmartStack STS16-20R Token Ring Switch has an input for a backup power supply (see Figure 22. in Chapter 4, “Installation”). It is compatible with the SmartStack STS-RPC Redundant Power Center, which can supply back-up power for up to six switches, when up to six SmartStack STS-PSU Redundant Power Supply Unit are installed in the chassis. This gives a high degree of resilience to power supply failures. The SmartStack STS16-20R will switch to the external power supply if the internal supply fails. The switch monitors the power source and informs the network management system which supply is in use.

The SmartStack STS-8SU Stacker Unit also accommodates an optional switch matrix STS-SM, which includes a redundant power supply, ensuring the highest degree of resilience in the stack of switches.

➽Caution: The redundant power supply unit SmartStack STS-PSU is not hot-swappable. Both the SmartStack STS-PSU unit and the switch must be off before connecting or disconnecting the DC power cable.
