SmartStack STS16-20D/STS16-20R Token Ring Switches Installation and User Guide

Preparing for Installation

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.
