Introduction
The Type 3 Power Module fits into the SuperStack 3 Advanced RPS
Chassis (3C16071, 3C16071A, or 3C16071B). The module provides
redundant power from the Advanced RPS chassis to the SuperStack 3
Switch 4900 Series.
You can use the Type 3 Modules in three ways:
■
Standard Usage
Connect the power module to the SuperStack 3 unit using the
standard DC cable supplied with this module. Provide AC mains
supply to the Advanced RPS chassis only. The power module acts
as a highly reliable power supply that can be swapped in the
event of failure.
■
Managed Redundancy.
Connect the power module to the SuperStack 3 unit using the
standard DC cable supplied with this module. Provide AC mains
supply to both the SuperStack 3 unit and the Advanced RPS
chassis. If the SuperStack 3 unit’s internal power supply fails, the
unit auto-enables the Advanced RPS. Alternatively, some
SuperStack 3 units use the Advanced RPS as their default power
supply, and if this fails they revert to their internal power supply.
Check the Getting Started Guide that accompanies your Switch
for more information. This set-up provides a managed redundant
(single module) configuration.
■
Full Redundancy
Connect two Type 3 Modules to the SuperStack 3 unit using the
optional ‘Y’ cable (3C16077) available from your supplier. Provide
AC mains supply to the Advanced RPS chassis only. If one, of the
modules fails, the other module will take the full load, and allow
you to “hot-swap” the faulty module, to return the system to full
redundancy. This set-up provides a fully redundant (resilient)
configuration.
CAUTION: If you need to replace a Type 3 Power Module used in a
full redundancy configuration, remove the ‘Y’ cable connection from
it before removing the module.
CAUTION: An energy hazard may exist on the Type 3 Power Module
DC connector when the Module is in the Advanced RPS chassis.

SuperStack 3 Advanced RPS Chassis Loading Limitations

SuperStack 3 Advanced RPS Chassis Loading Limitations
WARNING
: Do not overload the chassis
—
refer to Table 1
“Maximum Number of Advanced RPS Power Modules per Chassis” to
determine loading limitations. It is important that the loading
limitations are not exceeded.
ATTENTION
: Ne surchargez pas le châssis — référez-vous au
Tableau 1 "Maximum Number of Advanced RPS Power Modules per
Chassis" pour déterminer les limitations de charge. Il est important
que ces limitations de chargement ne soient pas excédées.
WARNUNG
: Bitte überlasten Sie nicht das Chassis —
bezugnehmend auf Tabelle 1 "maximale Anzahl der Advanced RPS
Powermodule per Chassis" und halten Sie die Limitierung ein. Es ist
wichtig, daß Sie die Limitierung nicht überschreiten.
Details of the permitted combinations of modules and 3Com
products are also given in Appendix C of the Advanced RPS Chassis
User Guide (DUA1607-0AAA0x).
Redundant (Single Module) Configuration
The maximum output DC power of the Advanced RPS is 480 W.
However, this can be exceeded only when installing two Type 3
Modules with no other power modules fitted. All other power
module combinations must not exceed 480 W. Refer to Table 1 for
more information on chassis loading limitations.
Fully Redundant (Resilient) Configuration
If you use two Type 3 Modules, connected by a ’Y’ cable in full
redundancy mode, these two modules count as one. This is because
a pair of power modules connected with a ‘Y’ cable draws the same
power as a single power module. In this configuration the modules
power-share, that is, the power drawn by both modules is the same
as that drawn by one module in the single module configuration,
however the ratio the power is drawn by each module can vary, for
example, 50:50, 40:60, and so on.
CAUTION:
You must not pair power modules of different types and
power ratings, for example, do not pair a 60 W Type 1 with a 100 W
Type 1, a Type 2 or Type 2A with a Type 3, and so on.

Important Safety Information
Installation and removal of the unit must be carried out by suitably
qualified service personnel only.
WARNING: Please read the following safety information in
conjunction with the safety information contained in the the
Advanced RPS Chassis User Guide before installing the module.
■
Use only the special cables designed and supplied for this

■
3Com require that you confirm that your chassis supports the
dual phase feature by checking that “3C16071A” or
“3C16071B” appears on the serial number label on the base of
the chassis, the front panel overlay, and also on the packaging
label. If the “A” or “B” suffix is not shown, the 3C16071 does
not provide dual phase support and must be powered from AC
sources of the same phase.
■
Disconnect both AC power leads before servicing.
■
Do not fit a Type 3 ‘Y’ cable to a Type 3 Power Module that is
being used in a single module configuration.

■
When you connect DC cables to a Type 3 Power Module you must
tighten the screws on all DC cable connectors with a suitable tool.
■
When connecting a DC cable to the power module, you must
take off the D-type connector protective cover by removing the
fixings with a suitable tool. Keep the cover and the fixings in a
safe place. If you disconnect the DC cable at any time, you must
then replace the protective cover.
CAUTION:

mettre sous tension à partir des sources de courant alternatif de la
même phase.
■
Débranchez les conducteurs électriques secteur avant de procéder
à une intervention d'entretien courant.
■
Il ne faut pas installer un câble ‘Y’ Type 3 sur un module de
puissance Type 3 utilisé dans une configuration à module unique.
■
Pour connecter un câble d’alimentation DC au module
d’alimentation Type 3 , vous devez d’abord ôter le capot de
protection du connecteur D-type en retirant les attaches à l’aide
d’un outil approprié. Conservez le capot et les attaches en lieu
sûr. Si vous devez déconnecter le câble CC, il vous faudra en effet
les remettre en place.

"3C16071A" oder “3C16071B” auf der Seriennummernplakette
an der Chassis-Basis, am Frontplatten-Overlay sowie am
Verpackungsetikett erscheint. Falls weder A moch B im suffix
erscheint, sorgt 3C16071 nicht für duale Phasenunterstützung
und muß von AC-Quellen derselben Phase gespeist werden.
■
Vor Wartungsarbeiten müssen beide Wechselstromnetzkabel
abgezogen werden.
■
Ausschließlich die für dieses Produkt konstruierten und
gelieferten Spezialkabel benutzen.
■
Kein ‘Y' Kabel Typ 3 an ein Power Module Typ 3, das in einer
Einzelmodul-Konfiguration benutzt wird, montieren.
■
Bei Verwendung von Power Module-Gleichstromkabeln Typ 3
müssen sämtliche Schrauben mit einem geeigneten Werkzeug
angezogen werden.
■
Bevor ein DC-Kabel an das Stromversorgungsmodul Typ 3
angeschlossen werden kann, muß die Steckerschutzabdeckung
Typ D entfernt werden, indem die Befestigungsschrauben mittels
eines geeigneten Werkzeuges gelöst werden.
Die Abdeckung und Befestigungsschrauben sicher aufbewahren.
Wird das DC-Kabel wieder abgezogen, muss die

Installing the Power Module
9
CAUTION:
Wenn sich das Type 3 Power Module im Advanced RPS
Chassis befindet kann es zu einer Energiegefahr am DC Stecker
kommen.
Installing the Power Module
CAUTION:
Never plug a hot
power module
into the Advanced RPS.
You may damage the power module. Allow sufficient time
(approximately 1 minute) for the module to cool down before
inserting it into the power module slot.
CAUTION:
It is important that the power modules are cooled
effectively. We strongly recommend installing the power modules as
evenly as possible between the top and bottom slots. Refer to Table 1
for recommendations on slot configurations for the Type 3 Module.
You can “hot-insert” the Type 3 Module into the chassis, that is, you
do not need to remove mains power from the chassis before you
insert a power module.
1
Take off the blanking plate by removing the fixing screw. Keep the
blanking plate and screw in a safe place. If you remove the module at
any time, you must replace the blanking plate to maintain the flow of
cooling air within the chassis.
2
Hold the power module so that the text on the front panel is upright,
and insert it into the chassis, sliding the module into the runners.
Push firmly to ensure the connectors are fully engaged.
3
Secure the module with the screws provided using a suitable tool.
CAUTION:
When removing a power module that has just been
operating, beware of hot components
.
CAUTION:
Do not operate the Advanced RPS continuously with any
of the rear slots open. This will disturb the flow of cooling air and
reduce the life of your unit.
