4.1 COMMISSIONING

The PMC is a high quality electronic machine that must be commissioned by a fully trained and authorized RITTAL field service engineer before being put into use.

The commissioning of the UPS involves the connection of the UPS and battery, the checking of the electrical installation and operating environment of the UPS, the controlled start-up and testing of the UPS and customer training.

Any PMC-System not commissioned by a RITTAL field service engineer or authorized service centre must be considered an electrical hazard and RITTAL accepts no responsibility for its safe operation or the safety of any personnel. Additionally, the manufacturer’s warranty is immediately invalidated if the UPS is put into use before it has been correctly commissioned.

4.2 CONTROL PANEL

The user-friendly control panel is composed of three parts:

• POWER MANAGEMENT LCD DISPLAY (PMD);

• LED INDICATORS;

• KEYS.

Figure 4.1 Control Panel.

4.2.1 Power Management Display (PMD)

The 2 x 20 character LCD simplifies the communication with the UPS and provides the necessary monitoring information about the UPS.

The menu driven LCD enables the access to the:

• EVENT REGISTER;

• Monitor the input and output U, I, f, P,

• Battery runtime;

• To perform commands like start-up and shut-down of UPS and

• Load transfer from INVERTER to BYPASS and vice-versa;

• DIAGNOSIS (SERVICE MODE);

4.2.4 ON/OFF Start-up and Shutdown Buttons

By pressing simultaneously both ON/OFF Buttons on the Control Panel the UPS may be switched on or shutdown. This is to prevent accidental start-up or shutdown of the UPS. The two main ON/OFF buttons are also used as a security LOAD–OFF-switch, making it possible to quickly disconnect the load from the UPS in emergency situations when a competent technician working on the UPS is in danger or if the UPS has some kind of anomaly.

A3346302IT74-GB 23

TO SHUT DOWN A UPS-MODULE YOU MUST PRESS BOTH ON/OFFBUTTONS SIMULTANEOUSLY ON CONTROL PANEL!

ACTIVATION OF THE ON/OFF BUTTONS WHEN THE UPS IS NOT IN MAINTENANCE BYPASS MODE CAN INTERRUPT THE POWER SUPPLY TO THE LOAD.

4.2.5 Definition of a Single/Parallel-Module System (DIP Switch SW1-1)

By means of the DIP Switch SW1-1, which is located on the front of a Module, it is possible to determine whether the Module is a:

• Single UPS (Switch Position LOW). On the right hand corner of the LCD you can read S (for Single)

• Parallel UPS (Switch Position HIGH). On the right hand corner of the LCD of the respective UPS-Modules you can read P01 (Master), P02 (slave) and P03 (Slave)

4.2.6 Definition of a Single/ Multi-Cabinet Chain (DIP Switch SW1-9)

By means of the DIP Switch SW1-9, which is located on the front of a Cabinet, it is possible to determine the “position” of the Cabinets in Multi-Cabinet Chain:

• “First” in the Multi-Cabinet Chain

• “Middle” in the Multi-Cabinet Chain (there may be more than one)

• “Last” in the Multi-Cabinet Chain.

NOTE: If a Cabinet is a Single Cabinet then it is seen as the “First” and “Last” in an imaginary Chain. So the positions of the DIP Switch SW1-9 must be set as shown below:

A3346302IT74-GB 27

4.4 OPERATING MODES

4.4.1 Mode "ON LINE" (INVERTER MODE)

The ON-LINE-Mode is the UPS-Operating Mode in which the load is supplied through the RECTIFIER and INVERTER.

Using the control panel (see figure 4.1), the UPS can easily be transferred to the ON-LINE-Mode. The ON-LINE-Mode provides the highest degree of protection, especially in the event of a mains disturbance or failure.

This operating mode is always recommended if the critical loads (computer systems) will not tolerate any interruption of the supply (not even the shortest).

In the unlikely event of an inverter fault or overload condition the UPS will transfer the load automatically and without interruption to the static bypass-mains supply (transfer time = 0).

4.4.2 Mode"OFF-LINE"(ECO- or BYPASS MODE)

In the "OFF-Line Mode”, the load is supplied from the mains through the static bypass.

Using the control panel (see figure 4.1), the UPS may be easily transferred to "Bypass Mode”.

When the UPS is operating in "Bypass Mode”, the efficiency of the system is higher. In the event of a mains failure the load will automatically be transferred from mains to inverter within 5 msec (this is valid for single and parallel systems). The battery charger remains active in the "BypassMode”.

The "Bypass-Mode”, is recommended only if the loads can tolerate interruptions of 3-5 ms (transfer time from Bypass Mode to ON-LINE Mode).

In order to provide the load with maximum protection RITTAL always recommends that the load be supplied by the inverter (ON-LINE-Mode).

BATTERY Green Green

Before transferring the load to Maintenance Bypass (IA1) always make sure all the UPS-modules are in the "Bypass-Mode” or “ECO-Mode”.

IF THE UPS IS OPERATING IN THE MAINTENANCE BYPASS MODE THROUGH THE BYPASS SWITCH THE LOAD WILL NOT BE PROTECTED IN THE EVENT OF A MAINS FAILURE. IT IS THEREFORE STRONGLY RECOMMENDED TO SWITCH OVER TO THE ON-LINE MODE (INV. ON) OR BYPASS MODE (OFFLINE MODE) AS SOON AS POSSIBLE.

4.4.4 Parallel Isolator (IA2)

Every UPS-unit (module) is provided with an output parallel isolator (IA2) which, when opened isolates the corresponding unit (module) from the PARALLEL BUS and from the LOAD. Once IA2 is open there is no power coming from its inverter.

In redundant parallel configurations it is used to isolate a unit from the parallel system without the need of transferring the load to bypass.

6 Multi-Cabinet Configuration

6.1 CONCEPT OF MULTI-CABINET CONFIGURATION

The PMC Extended Twin-Cabinets may be paralleled for power capacity PMC Basic or for redundancy indefinitely. Every standard PMC is provided with the parallel option and therefore no time-consuming upgrading is necessary on site.

UPS 1 UPS 2 UPS n

Fig. 6.1. PMC Extended Twin Multi-Cabinet Chain.

The Multi-Cabinet Chain is based on a decentralised bypass architecture i.e. every UPS is provided with its own static bypass. In a parallel system there is always one Master Module and the other Modules are slaves. If at any time the master is faulty the next UPS (former slave) will immediately take over the master function and the former master will switch off.

Every UPS unit in a parallel configuration is provided with a proper output parallel Isolator (IA2) which, when opened isolates the corresponding unit from the parallel system. Once the parallel isolator (IA2) of a unit is open that unit (module) is isolated from the rest of the parallel system and therefore does not provide power to the output.

For example if you perform the command “LOAD TO BYPASS” on any unit, all the units will transfer the load simultaneously to mains and if you perform the command “LOAD TO INVERTER” on any unit all the UPS’s will simultaneously transfer the load to the inverters.

The PMC is paralleled for redundancy (highest availability) or for power parallel systems.

IMPORTANT: The BYPASS MODE (ECO-MODE) function of a parallel systems is the same as in single units of PMC. If in a parallel UPS system the load is transferred to the BYPASS (load on mains) and if the mains fails, the UPS’s will all be automatically transferred to inverter within 5msec.

In order to provide the load with maximum protection RITTAL always recommends that the load be supplied by the inverter (ON-LINE-Mode).

6.2 INSTALLATION INSTRUCTIONS

6.2.1 Introduction

ELECTRICIANS OR BY QUALIFIED INTERNAL TRAINED PERSONNEL.

BY OPENING OR REMOVING THE UPS-MODULES AND MODULE COVERS YOU RUN RISK OF EXPOSURE TO DANGEROUS VOLTAGES!

BEFORE REMOVING A UPS-MODULE MAKE SURE THE INTERNAL DCCAPACITORS HAVE BEEN DISCHARGED FOR AT LEAST 2 MINUTES.

DO NOT EVER LEAVE THE UPS-MODULE COMPARTMENT WITHOUT AN APPROPRIATE PROTECTION COVER.

RITTAL WILL NOT TAKE RESPONSIBILITY OR BE LIABLE FOR PERSONNEL INJURIES OR MATERIAL DAMAGES CAUSED BY IMPROPER MANIPULATION OF THE UPS, OR BY INCORRECT CABLING. THE PROPER INSTALLATION AND USAGE INSTRUCTIONS OF THE UPS ARE DESCRIBED WITHIN THIS MANUAL AND MUST BE STRICTLY ADHERED TO.

DO NOT ATTEMPT TO COMMISSION A PARALLEL CABINETS SYSTEM WITHOUT CAREFULLY READING THIS USER MANUAL (SEE ALSO CHAPTERS 3 AND 4

NOTE: IN ORDER TO ACHIEVE EQUAL LOAD SHARING BETWEEN THE UPS-CABINETS, THE INPUT CABLE LENGTHS FROM THE INPUT DISTRIBUTION BOARD TO THE UPS AND FROM THE OUTPUT CABLE TO THE OUTPUT DISTRIBUTION BOARD SHOULD BE THE SAME RESPECTIVELY. WHEN CABLING THE UPS’S BEWARE TO CONNECT INPUT AND OUTPUT WIRES TO THE CORRESPONDING TERMINALS, RESPECTING THE SAME PHASE SEQUENCE ON ALL UPS CABINETS. EXAMPLE: PHASE1 UPS1 = PHASE1 UPS2 = …… = PHASE1 UPS n

WHEN CABLING THE UPS’s MAKE SURE THAT THE UPS’s ARE COMPLETELY VOLTAGE FREE. CHECK THAT THE MAINTENANCE BYPASSES (IA1) AND ALL PARALLEL ISOLATOR (IA2) ARE OPEN (“OFF”) ON ALL CABINETS.

6.2.2 Paralleling of UPS-Cabinets

6.2.2.1 Connection of Parallel Communication Cables (BUS-lines)

For the correct performance of different parallel functions and operations the parallel units communicate continuously between each other. This is achieved by means of the so-called communication BUS-Lines.

After terminating the input and output cabling of each single UPS, it is necessary to connect the units together to form the parallel system. For this purpose a communication BUS line is connected sequentially between the units. Connect communication BUS lines according to Figure

6.2.

NOTE: CONNECT THE BUS CABLES ONLY WITH SWITCHED OFF UPS AND OPENED PARALLEL ISOLATORS IA2. RESPECT THE FOLLOWING CONNECTION SEQUENCES.

1. Fit the Parallel Adapter over the Connector JD8 on all UPS-cabinets

2. Set DIP Switch SW2-2 on each Parallel Adapter depending on the UPS Cabinet in the parallel cabinet configuration (see page 45)

3. Connect PORT JD6 on Parallel Adapter of UPS-Cabinet 1and PORT JD5 of Parallel Adapter of UPS-Cabinet 2 with the corresponding BUS-Cable;

4. Connect PORT JD6 on Parallel Adapter of UPS-Cabinet 2 and PORT JD5 of UPSCabinet 3 with the corresponding BUS-Cable

5. Continue in the same manner for the remaining UPS-Cabinets.

Figure 6.2.Connection of the Bus Lines when paralleling UPS-Cabinets by means of Parallel Adapters.

6.2.2.2 Parallel Adapater and DIP-Switch SW2-2

If the UPS-CABINETS are paralleled the Parallel Adapter will be placed on the Connector JD8 on the distribution panel and the communications cables between the cabinets will be connected through the connectors JD5 and JD6, as we are doing now.

NOTE: set the Switch SW2-2 correctly according to the corresponding cabinet configuration.

6.2.3 DIP-Switch SW1-1 and SW1-9 Settings

Before starting up the parallel system it is necessary to set the DIP Switches SW1-1 and SW1-9 to their correct positions.

DIP Switch SW1-1

The DIP Switch SW1-1 is located on every UPS-Module and serves to define if the UPS-Module is a single or parallel Module.

SW1-1 has two positions:

HIGH = Parallel (the Module is in a parallel system) LOW = Single (the Module is a single UPS)

In the case of parallel cabinet configurations the SW1-1 on all Modules is always in position HIGH = Parallel.

DIP Switch SW1-9

The DIP Switch SW1-9 is located on every Cabinet (PMC Extended Twin) and not on Modules. With this switch it is possible to determine the “position of an PMC Extended Twin-Cabinet” in a Multi-Cabinet Chain. Define each PMC Extended Twin-Cabinet in a Multi-Cabinet Chain as:

1. The “First”,

2. The “Middle” (there may be more than one) and

3. The “Last”

Cabinet in the Multi-Cabinet Chain by setting the DIP Switch SW1-9 on each cabinet according to the Table below:

Middle Cabinet

Last Cabinet

1 ON ON OFF ON 2 ON ON OFF ON 3 ON ON OFF ON 4 ON ON OFF ON 5 ON ON OFF ON 6 ON ON OFF ON 7 ON ON OFF ON 8 ON ON OFF OFF 9 ON OFF OFF ON

After having set the SW1-1 on all UPS-Modules and SW1-9 on all the PMC Extended TwinCabinets correctly the UPS’s may be commissioned

6.2.4 ON/OFF – Main Buttons

The ON/OFF-Buttons serve to shutdown the UPS-system for service or maintenance or for emergency reasons.

IF BOTH ON/OFF-BUTTONS ARE PRESSED ON THE UPS-Module IN A MULTIModule SYSTEM ONLY THAT PARTICULAR UPS-Module WILL SHUTDOWN. TO SHUTDOWN THE COMPLETE SYSTEM PRESS BOTH ON/OFF-BUTTONS ON EVERY UPS-MODULE OF A MULTI-MODULE SYSTEM .

6.2.5 Parallel Isolator (IA2)

Every UPS-unit is provided with a parallel isolator IA2. The parallel isolator is an important element of the UPS-unit, that allows the isolation of a unit from the parallel system without the need to transfer the load to bypass.

IA2 OPEN: THE CORRESPONDING UPS-MODULE IS ISOLATED FROM THE OUTPUT. THERE IS NO COMMUNICATION BETWEEN THE ISOLATED UNIT AND THE REST OF THE PARALLEL SYSTEM. THE ISOLATED UPS-MODULE MAY BE REPLACED WITHOUT COMPROMISING THE REST OF THE SYSTEM. IA2 CLOSED: THE CORRESPONDING UPS IS BEING ADDED TO THE REST OF THE PARALLEL SYSTEM.

IMPORTANT: BEFORE CLOSING THE IA2 OF A UPS-MODULE BE SURE THAT THE STATUS OF THAT UPS-MODULE IS THE SAME AS OF THE REST OF THE OPERATING UPS-MODULE WITH CLOSED IA2. EXAMPLE: IF ALL UPS’s WITH CLOSED IA2 ARE ON INVERTER, MAKE SURE THAT THE UNIT ON WHICH ISOLATOR IA2 IS BEING CLOSED IS ALSO ON INVERTER.

6.2.6 Maintenance Bypass (IA1)

There are two types of Parallel System Configurations: redundant and capacity parallel systems (see Chapter 5).

A3346302IT74-GB 46

6.2.6.1 Redundant Parallel Configuration

In a redundant parallel system a UPS-module may easily be isolated from the parallel system by opening the respective isolator (IA2). It is now possible to operate or shut down this unit without influencing the rest of the parallel system. The rest of the parallel system will continue to protect the load. The isolated UPS-Module may be replaced without the need of transferring the load to bypass by means of the Maintenance Bypass (IA1).

6.2.6.2 Capacity Parallel Configuration

In the event of a fault in one of the UPS-Modules in a capacity parallel system the load will automatically be transferred to static bypass (mains). In order to replace the faulty module the load must be transferred to mains by means of Maintenance Bypass (IA1).

6.2.7 ECO-MODE (BYPASS MODE) in Parallel Systems

The Eco-Mode function in a Parallel System is the same as in Single Systems. If in a PMC Parallel System the load is supplied by the mains(load on mains) and in the event of mains failure, all UPS’s will automatically transfer the load back to the inverters with 5msec.

In order to provide the load with maximum protection RITTAL always recommends that the load be supplied by the inverter (ON-LINE-Mode).

6.3 COMMISSIONING OF MULTI-CABINET CONFIGURATION

6.3.1 Start-up of a Multi-Cabinet Configuration

Before starting up a Multi-Cabinet Configuration verify that:

1. All the input and output cabling has been performed correctly according to Chapter 3 of this User Manual;

2. The parallel communication cables have been connected correctly according to Paragraph 6.2.2 of Chapter 6;

3. All the DIP Switches for the Modules and PMC Extended Twin-Cabinets been set correctly according to Paragraph 6.2.3 of Chapter 6;

4. All the external battery cabinets/racks have been connected correctly;

The start-up of a Multi-Cabinet Configuration may be performed in analogy to the start-up procedures for a single PMC Twin-Cabinet described in Paragraph 4.5 of Chapter 4.

6.3.2 Shutdown of Multi-Cabinet Configuration

Before shutting-down of a Multi-Cabinet Configuration make sure that the loads do need power protection and that they are disconnected.

A3346302IT74-GB 47

The UPS may be shut down completely if the loads do not need any power supply. Therefore the steps in this Paragraph are to be performed only after the load has been disconnected and does not need any power supply.

To perform a complete shutdown of a Multi-Cabinet Configuration proceed in analogy to the shutdown procedures described in Paragraph 4.6 of Chapter 4.

6.3.3 Replacement of a Faulty UPS-Module in a Multi-Cabinet Configuration

If in a Multi-Cabinet Configuration a UPS-Module fails proceed in replacing the UPS-Module in analogy with the replacement procedures described in Chapter 5 of this User Manual.

A3346302IT74-GB 48

7 Maintenance

7.1 INTRODUCTION

ALL THE OPERATIONS IN THIS SECTION MUST BE PERFORMED BY AUTHORISED ELECTRICIANS OR BY QUALIFIED INTERNAL PERSONNEL.

To ensure an optimum operation of the PMC and a continuous and efficient protection of the connected load it is recommended to check the batteries every 6 months, depending on the ambiance temperature.

7.2 USER RESPONSIBILITIES

There are no user serviceable parts contained within the UPS so the maintenance responsibilities of the user are minimal. To maximise the useful working life and reliability of the UPS and its batteries, the environment in which the UPS operates should be kept cool, dry, dust and vibration free. The batteries should be hold fully charged.

7.3 ROUTINE MAINTENANCE

The UPS is designed to receive regular preventative maintenance inspections. These preventative maintenance inspections are essential to ensure that both the useful working life and the reliability of the UPS are maximised. When the UPS is commissioned, the commissioning field service engineer will attach a service record book to the front of the UPS and this will be used to record the full service history of the UPS.

Preventative maintenance inspections involve working inside the UPS, which contains hazardous AC and DC voltages. Only RITTAL trained or agreed service personnel and authorised field service engineers are fully aware of all of the hazardous areas within the UPS.

During a preventative maintenance inspection the field service engineer will carry out the following checks:

• Site/environment conditions;

• Integrity of electrical installation;

• Cooling airflow;

• Rectifier operation and calibration;

• Inverter operation and calibration;

• Static switch operation;

• Battery status;

• Load characteristics;

• Integrity of alarm and monitoring systems;

• Operation of all installed options;

7.4 BATTERY TEST

The battery test takes approx. 3 minutes and should be performed only if:

• there are no alarm conditions;

• the battery is fully charged;

• mains is present.

The battery testing can be carried out independently of the operation mode (OFF-LINE or ONLINE) and whether or not the load is connected.

The battery test procedure can be performed from the UPS front panel. See “Operation” Chapter 4.

A3346302IT74-GB 49

9.5 POWER MODULAR CONCEPT-SOFTWARE SHUTDOWN AND MANAGEMENT SOFTWARE

9.5.1 Why is UPS Management important?

By combining a UPS with network management products, such as an SNMP protocol, System-administrators are guaranteed their data and their system will constantly be protected from corruption or data loss even in the event of an extended power failure or when batteries reach a critical low state. In the event of a power disturbance system administrators can also monitor their network from a central location, allowing an early detection of problems. In fact utility power is unreliable at times, ensuring that all network systems have constant power can be a difficult task. The situation becomes even more complex if systems are managed across a Local Area Network (LAN) or Wide Area Network (WAN) around the world.

When a power failure occurs action can be taken to protect the system and its valuable data. If no action is initiated by the operator, this event can seriously damage the system. The UPS software will react automatically in such a case and shutdown the operating system. RITTAL has found it important to have a complete solution for its UPS and is able to offer a wide range of monitoring/remote controls for assuring the maximum protection degree to the RITTAL customers.

9.5.2 Power Modular Concept-Software Shutdown and Monitoring Software

Power Modular Concept PMC-Software is an external monitoring and shutdown software which

was designed to operate with all RITTAL UPS products, both with the DRY PORT (Relays) JD2 and SMART PORT (RS232) JD1.

The software packet consists of a CD ROM for most diffused operating systems (Windows, Unix, OS/2, DEC VMS, Novell, Apple), a standard connection and a user manual.

The 25 pin port with voltage-free contacts may also be used for automatic shutdown in connection with PMC-Software. It is necessary to provide a special cable to connect the 25 pin port of the UPS and the serial port of the server.

Figure 9.5. Monitoring image.

The main characteristics of PMC-Software are:

• Automatic unattended master/slave shutdown in heterogeneous networks

• On-screen autonomy time / battery time countdown

• On-screen server log off and shutdown procedure

• Extensive logging of all UPS activity and power quality data, with timestamp

• Scheduled UPS economy mode, service mode, other systems status

• Graphical user interface for Windows compatible platforms

• Automatic unattended local shutdown

A3346302IT74-GB 54

• Special software modules to close and save open MS-Office documents.

• Compatible for all optional modules like UPSDIALER, SNMP adapters,

Temperature sensors, etc.

The UPS-Management Software is a client-/server-application for networks and local workstations. Basically PMC-Software consists of two parts: the server-module of the UPSManagement Software is UPSServ, which communicates via RS-232 cable with the UPS. Working as a background process the UPSServ collects messages, received from the UPS. The UPSServ interprets received messages and makes them available to the client-module UPSCli and to any SNMP-based management station.

When UPSServ detects voltage variations or a power failure it can execute various so called system „event routines“, which for example may shutdown the server or send warning to connected users. These system event routines which are a part of the UPS-Management Software can be adjusted to your demands.

The UPS management software includes with every serial number the licence for using the UPS service on one server with one UPS and an unlimited numbers of connected WINDOWS workstations. When operating with two or more servers a licence for every additional server is required. It doesn’t matter if the UPS service runs at that location or if the server is halted by a UPS service via remote command. The same regulations are applicable to the use of remote send/receive modules RCCMD and multiserver shutdown under NT, UNIX and other operating systems. The service programs are generally delivered as a single-licence. To use a single CD ROM to shutdown multiple servers you have to purchase additional CD license keys.

Parallel/redundant UPS systems are also manageable by the software.

The main principle is: let introduce a shutdown of a Server only when strictly necessary. A correct Parallel Handling has therefore to manage a parallel system as a whole and always considering redundancy. Following statements apply:

- Every alarm on any unit is immediately notified, but …

- … a reaction to a severe fault is introduced only when the minimum number of UPS – Modules necessary to supply the load exhibits an alarming situation.

- The real Battery autonomy time of the (whole) parallel system is computed continuously.

- Maintenance on a redundant unit may be executed without annoyance to the management system (supervisor).

In order to be managed, a RITTAL UPS can be integrated into a network in two ways:

1. By means of the server which is being powered by the UPS and is integrated in the

network. In most of the cases the server is used as sub-agent and you only need the PMCSoftware without any SNMP Adapter. You need a standard serial connection between the RS232 SMART port of the UPS and the RS232 port of the computer/server.

2. In some situations it is preferable to interface the network via an SNMP adapter. By this way

up to 50 computers can be shut down in a RCCMD environment. RCCMD (Remote Console Command) is an additional software module, which can be triggered by the SNMP device to executes a command (typically a shutdown command) on a remote system.

A3346302IT74-GB 55

9.6 SNMP CARD/ADAPTER FOR NETWORK MANAGEMENT /REMOTE MONITORING

The Simple Network Management Protocol (SNMP) is a worldwide-standardized communication-protocol. It is used to monitor any device in the network via simple control language. The UPS-Management Software also provides its data in this SNMP format with its internal software agent. The operating system you are using must support the SNMP protocol. We offer our software with SNMP functionality for Novell, OS/2, all Windows running on INTEL and ALPHA, DEC VMS, Apple.

Two types of SNMP interfaces with identical functionality are available: an external SNMPAdapter (Box) and an internal SNMP-Card. Both can manage a parallel system (N modules) and return either global values - which are consistent for the whole parallel system - or specific values from the single modules.

Figure 9.6 SNMP Adapter

The adapter may be configured via Telnet, HTTP (Web-Browser) or serial connection (Terminal). For normal operation at least one network connection (Ethernet) is required.

The SNMP adapter can be used, utilising the RCCMD send function, for an automatic network wide shut down or just for informing connected users. The shut down procedure can be initiated on a low residual battery autonomy time (downtime) or by a countdown timer which is started at the beginning of the alarm. A shut down is therefore possible without extra input from the operator, and is fully software controlled.

The small (125x70 mm) External SNMP adapter comes with following interfaces:

1. RJ-45 connector for 10/100 Base-T(autoswitchable)

2. Serial Port for configuration (COM2) or optional ModBus interface.

3. Error/Link LED for UPS status

The Internal SNMP-Card can be inserted into an appropriate extension slot of the PMC. This adapter communicates via the serial port of the UPS and makes a direct multiple server shut down possible without additional SNMP management software.

Figure 9.8 Internal SNMP Adapter

For detailed information please see Software Manual provided with the PMC-Software CD ROM.RCCMD - Remote Console Command module for a multi-server shutdown. This stand-alone software module is designed to receive and execute a command issued by a remote device. Thanks to RCCMD it is possible to execute a shutdown in an heterogeneous multiplatform network. The new release RCCMD2 is an application available for all Operating Systems, analogous to PMC-Software. Our SNMP Interfaces are compatible to RCCMD.
