Juniper EX3300 Complete Hardware Guide

Advarsel Når enheten installeres, må jordledningen alltid tilkobles først og
frakobles sist.
Aviso Ao instalar a unidade, a ligação à terra deverá ser sempre a primeira a
ser ligada, e a última a ser desligada.
¡Atención! Al instalar el equipo, conectar la tierra la primera y desconectarla
la última.
Varning! Vid installationav enheten måste jordledningen alltid anslutas först
och kopplas bort sist.

DC Power Wiring Sequence Warning
This topic applies to hardware devices in the EX Series product family, which includes
EX Series switches and the XRE200 External Routing Engine.
This topic also applies to hardware devices in the QFX Series and to OCX1100 switches.
WARNING: Wire the DC power supply using the appropriate lugs. When
connecting power, the proper wiring sequence is ground to ground, +RTN to
+RTN, then –48 V to –48 V. When disconnecting power, the proper wiring
sequence is –48 V to –48 V, +RTN to +RTN, then ground to ground. Note
that the ground wire must always be connected first and disconnected last.
Waarschuwing De juiste bedradingsvolgorde verbonden is aarde naar aarde,
+RTN naar +RTN, en –48 V naar – 48 V. De juiste bedradingsvolgorde
losgemaakt is en –48 naar –48 V, +RTN naar +RTN, aarde naar aarde.
Varoitus Oikea yhdistettava kytkentajarjestys on maajohto maajohtoon,
+RTN varten +RTN, –48 V varten – 48 V. Oikea irrotettava kytkentajarjestys
on –48 V varten – 48 V, +RTN varten +RTN, maajohto maajohtoon.
Attention Câblez l'approvisionnement d'alimentation CC En utilisant les
crochets appropriés à l'extrémité de câblage. En reliant la puissance, l'ordre
approprié de câblage est rectifié pour rectifier, +RTN à +RTN, puis –48 V à
–48 V. En débranchant la puissance, l'ordre approprié de câblage est –48 V
à –48 V, +RTN à +RTN, a alors rectifié pour rectifier. Notez que le fil de masse
