Installation
CAUTION ! Electrostatic sensitive devices Electrostatic sensitive devices are protected against destruction by electrostatic charge by means of protective structures at the inputs and outputs. In unfavourable cases, however, plastic floor coverings, non-conductive work surfaces, or clothing containing artificial fibres can result in such high charges that electrostatic sensitive devices can be damaged or even destroyed despite the protective networks mentioned. If a device is damaged its reliability decreases drastically, although it may be a long time before the effects of the damage are noticeable. In order to ensure that electrostatic charges are eliminated harmless when working on the system you must observe the following points without fail: 1. Before carrying out any work on the system ground yourself with a wrist strap.
2. When working on modules always place them on a grounded, conductive surface
3. Only transport modules in suitable protective bags. The following points must also be observed during installation:
DANGER!
!
The device has to be installed in a locked room, with admission for commissioning personal only. It must be excluded that other persons except the commissioning personal has access to this equipment.
ATTENTION! Sufficient cooling has to be provided!
1. Before installing the device the grounding wire must first be laid and connected to ground potential.
2. Connect the grounding wire immediately after installing the device or setting up the cabinet.
3. Use shoe grounding strips. Warning! There is a risk of electrostatic discharge up until the grounding wire has been connected even if you are wearing a wrist strap. If possible you should therefore not touch modules and wiring before then. When dismantling the system the grounding wire must not be disconnected until all work has been completed.

SNMP General information The SNMP Terminal Server contains OSS - Open Source Software (µCLinux and Net-SNMP). For the copyright notice, list of conditions, disclaimer information kindly refer to the referenced source. Open Source Software for µCLinux as well as detailed license information documentation is available and delivered with the PowerSys CD ROM. SNMP function The SNMP server allows the request of system parameters and a limited control (commands) of the SWT 3000 from a central NMS (network management system) via TCP/IP. The SNMP server provides an image of the SWT 3000 status. Spontaneous alarm indications (traps) are transmitted to the NMS. Alternatively the remote access of the service program PowerSys via the SNMP server is also possible and has higher priority. This means during an existing connection with the service program the SNMP data base is not updated. This status is reported with a spontaneous indication (trap) to the NMS. Station A

Trap destination configuration The NMS addresses as well as the community string for set /get has to be adjusted via web login and must match between the SNMP server and the NMS. The min active time adjustable between 0 – 3000 sec, is the minimum time the alarm has to be active before a rising trap is sent. The fall down delay adjustable between 0 – 3000 sec, is the min time the alarm has to be inactive before a falling trap is sent. Both adjustments are used to prevent a sequence of events in case of cyclic alarm indications. NMS commissioning The necessary MIBs are available on the PowerSys CD provided with the PowerLink system. They have to be integrated in the NMS. After the NMS has been configured, traps from the SNMP server are received. It is also possible to read PowerLink (ref. to page 10) resp. iSWT information (ref. to page Fehler! Textmarke nicht definiert.) or configuration (ref. to page 10). Commands can be set as well from the NMS (ref. to page 10). Access to the PowerLink via the SNMP server is also possible with the PowerSys service program. In this case the connection to the NMS is interrupted. A corresponding trap is sent from the SNMP server. Network time protocol NTP Activation of the NTP (NTP synchronization ;) offers the possibility to synchronize the timer of the iSWT with the network time protocol. The NTP server is the PC in the network providing the time. Enter either the IP address or the internet address. The Time zone is always the GMT. Please select the local deviation (±12h). The Poll interval describes how often the time is read from the NTP server.

SWT 3000 Remote Access General information A remote access server (RAS) connection serves complete system functionality administration identical to local on-site operation. Standard TCP/IP network protocols are used for easy access to each SWT 3000 from anywhere within a company Intranet. The system can interface with your own network security systems and firewalls, providing you with just the right security level your company requires. The remote access to the SWT 3000 is possible with the service program PowerSys. With the PowerSys menu the connection to the device via serial interface or TCP/IP has to be configured.

With the optional service “Remote Monitoring” (RM), data can be transmitted between the devices of one or more SWT 3000 routes. The RM function enables the user to have access via a serial interface with the service program to the following function: y
query of the device data (configuration, parameter, status) of the remote device
y
temporary adjustments (e.g. test loops)
y
producing a reset
Via an additional interface (service interface backplane SSB) up to 5 transmission routes can be coupled. Station 1
Station 2
Station 3....

Changing of the configuration and parameter (except date / time of the SWT 3000) in the remote device is possible if the configuration via inband RM channel is activated (see figure below).

The figure below shows the remote connection to the SWT 3000 in station A via RAS or terminal server. The access to the SWT 3000 devices in station B and C is possible when the RM in-band channel is activated. For the SSB - SSB connection in station B a crossed cable has to be used. One SSB interface must be configured as “Slave” the other one as “Master”. Station A
