b.The cord must be UL listed, CSA labelled, and consist of three conductors with a maximum of 15 feet in length. Type SVT or SJT cord sets shall be used for units which stand on a desk or table. Type SJT cord sets shall be used for units which stand on floor.

c.The male plug for units operating at 115 VAC shall consist of a parallel blade, grounding type attachment plug rated 15 A, 125 VAC.

The male plug for units operating at 230 VAC shall consist of a tandem blade, grounding type attachment plug rated 15 A, 250 VAC.

The male plug for units operating at 230 VAC (outside of the United States and Canada) shall consist of a grounding type attachment plug rated 15 A, 250 VAC and have the appropriate safety approvals for the country in which the equipment will be installed.

Caution: Support the SmartStack STS16-20D Token Ring Switch and/or the SmartStack STS16-20R Token Ring Switch while you are installing the unit to avoid dropping it on the floor or any equipment beneath it in the rack. The SmartStack STS16-20D Token Ring Switch and the SmartStack STS16-20R Token Ring Switch unit each weighs approximately 7.2 kg (15.9 lbs).

Caution: To separate the switch from the power, pull the power cord completely out from the socket. The power socket must be easily accessible and located near the unit.

Warning: All RJ-45 connectors must only be connected to safety extra low voltage (SELV) circuits like local area networking (LAN).

Warning: This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than

120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors).

Warning: A voltage mismatch can cause equipment damage and may pose a fire hazard. If the voltage indicated on the label is different from the power outlet voltage, do not connect the chassis to that receptacle.

Caution: If you are using the redundant power supply unit SmartStack STS-PSU (only available for SmartStack STS16-20R), note that this unit is not hot- swappable. You must turn off the SmartStack STS-PSU Unit and the switch before connecting or disconnecting the DC power cable.
