Wichtige Sicherheits hinweis e

1. Bitte les en Sie diese Hinw eise sorgfaltig durch.

2. Heben Sie diese Anleitung fur den spateren Gebrauch auf.

3. Vor jedem Reinigen ist das Gerat vom Stromnetz zu trennen. Verwenden Si e keine Flussigoder A erosolreiniger.
Am besten eignet sich ein angefeuchtetes Tuch zur Reinigung.

4. Um eine Beschadigung des Gerates zu vermeiden sollten Si e nur Zubehorteile v erwenden, die vom Hersteller
zugelassen sind.

5. D a s G e ra t ist vor Feuch tigke it zu sc hutze n .

6. Bei der Aufstellung de s G erates ist auf sicheren Stand zu achten. Ein Kippen oder Fallen ko nnte Verletzungen
hervorrufen. Ver w enden Sie nur sichere Standorte und beachten Sie die Aufste llhinweise des Herstellers.

7. Die Beluftungsoffnungen dienen der Luftzirkulation die das Gerat vor Uberhitzung schutzt. Sorgen Sie dafur,
daB diese Offnungen nicht abgedeckt wer den.

8. Beachten Si e beim AnschluB an das Stromnetz die AnschluBwerte.

9. Die Netzanschlusteckdose muB aus Grunden der elektrischen Sicherheit einen Schutzleiterkontakt haben.

10. Verlegen Sie die Netzan schluBleitung so, daB niemand daruber fallen kann. Es sollte auch nichts auf d er Leitung
abgestellt werden.

11. Alle Hinweise und Warnungen, die sich am Geraten befinden sind zu beachten.

206375-A

iii

12. Wird das Gerat uber einen langeren Zeitraum nicht benutzt, sollten Sie es vom Stromnetztrennen. Somit wird im
Falle ei ner Uberspannung eine Beschadigung verm ieden.

13. Durch die Luf tungso f f nungen dur fe n niem a ls Ge gen st ande od er Flu ssi gkei t en in d as Gera t gel angen. Di es ko nnte
einen Brand bzw. elektrische n Schlag auslosen.

14. Offnen sie niemals das Gerat. Das Gerat darf aus Grunden der elektrischen Sicherheit nur von authorisiertem
Servicepersonal geoffnet werden.

15. Wenn folgende Situ ationen auftrete n ist das Gerat vom Stromnetz zu trennen und von einer qua lifizierten
Servicestelle zu uberprufen:

a Netzkabel oder Netzstecker sind beschadigt.
b Flussigkeit is t in das Gerat eingedrungen.
c Das Gerat w ar Feuchtigkeit ausgesetzt.
d Wenn das Gerat nicht der Bedienungsanleitung entsprechend funktioniert oder Sie mit Hilfedieser Anleitung

keine Verbesserung erzielen.
e Das Ger at ist gefallen und /oder das Gehause ist beschadigt.
f Wenn das Gerat deutliche Anzeichen eines Defe ktes aufweist.

16. Bei Reparat uren durfen nur Orgi nalersatzteile bzw. den Orginalteilen entsprechende Teile verwendet wer den.
Der Einsat z von ungeeigneten Ersatzteile n kann eine weitere Beschadigung hervorrufen.

17. Wenden Sie sich mit al len Fragen die Service und Repartur betreffen an Ihren Servicepartner. Somit stellen Sie
die Betriebssicherheit des Gerates sicher.

18. Zum Netzan schluB dieses Gerates ist eine geprufte Lei tung zu verwenden. Fur einen Nennstrom bis 6A und
einem Gerategewicht gr oBer 3kg ist eine Leitung nicht leichter als H05VV-F, 3G, 0.75mm 2 einzusetzen. Der
arbeitsplatzbezogene Schalldruckpegel nach D IN 45 635 Teil 1000 betragt 70dB(A) oder weniger.

Chapter 1

Introduction

This chapter give s you an overview of the three BayStack 70 Series 10/100
Ethernet Switches. The chapt er describes the front and rear panels of each switch
and explains in detail the components on each of the panels. The chapter lists the
key features of the switches.

BayStack 70 Series 10/100 Ethernet Switches Overview

The BayStack 70-8T, 70-16T, and 70-24T 10/100 Ethernet switches are
autosensing 10/100 Mb/s switches. The BayStack 70-8T 10/100 Ethernet Swi tch
and BayStack 70-16T 10/100 Ethernet Switch are intended for use on desktops or
other level surfaces. The BayStack 70-24T 10/100 Ethernet Switch can be used
either as a desktop switch or as a segment switch in a wiring closet environment,
mounted in a standard 19-inch equipment rack.

All ports on a BayStack 70 Series 10/100 Ethernet S witches can autosense their
