DC Power Wiring Sequence Warning
This topic applies to hardware devices in the EX Series product family, which includes
switches and the XRE200 External Routing Engine.
This topic also applies to hardware devices in the QFX Series.
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 RTN, –48 V varten – 48 V. Oikea irrotettava kytkentajarjestys
on –48 V varten – 48 V, +RTN 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
devrait toujours être relié d'abord et débranché pour la dernière fois. Notez
que le fil de masse devrait toujours être relié d'abord et débranché pour la
dernière fois.
Warnung
Die Stromzufuhr ist nur mit geeigneten Ringösen an das DC Netzteil
anzuschliessen. Die richtige Anschlusssequenz ist: Erdanschluss zu
Erdanschluss, +RTN zu +RTN und dann -48V zu -48V. Die richtige Sequenz
zum Abtrennen der Stromversorgung ist -48V zu -48V, +RTN zu +RTN und
