2SUPERSTACK®3 ADVANCED RPS TYPE 3 POWER MODULE (3C16075) INSTALLATION GUIDE

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 3

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, daßSie 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.

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.

1Take 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.

2Hold 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.

3Secure 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.
