1 Product Overview 1.1 Functional Overview The RuggedSwitch RS900L is an 8 port industrially hardened, fully managed Ethernet switch supporting Ethernet over VDSL allowing up to 2.5 km LAN segments over telephone grade cable at up to 35 Mbps. The RS900L has one EoVDSL port plus two optional fiber optic ports allowing a cascaded Ethernet network to span hundreds of kilometers over any combination of telephone and fiber optic cable.

2.2 Power Supply Wiring and Grounding 2.2.1 AC Power Supply Wiring and Grounding Figure 4 - Power Supply Inputs The AC power supply inputs should be connected as follows: 1. +/L should be connected to AC Line/Hot. 2. -/N should be connected to AC Neutral. 3. Surge Ground should be connected to the Chassis Ground via a braided cable or other appropriate grounding wire. Surge Ground is used as the ground conductor for all surge and transient suppression circuitry internal to the unit. 4.
2.2.2 DC Power Supply Wiring and Grounding Figure 5 - DC Power supply wiring and grounding diagram The low voltage DC power supply features reverse polarity protection and dual independent inputs. The latter feature allows the connection of two DC sources with the same nominal voltage to provide redundant power supply inputs. The DC power supply inputs should be connected as follows: 1. Connect to the DC inputs according to the polarity markings on the unit. 2.
2.2.3 Failsafe Output Wiring The Failsafe output relay is provided to signal critical error conditions that may occur on the unit. The contacts are energized upon power up of the unit and remain energized until an alarm condition or power loss occurs. The behavior of the failsafe relay is configurable via the RuggedSwitch Operating System. Consult the RuggedSwitch Users Guide for details. Figure 6 - Failsafe Output Relay 11 2007 RuggedCom Inc.
2.2.4 Dielectric Strength Testing Units which are to have dielectric strength testing (HIPOT testing) done in the field must have the braided ground cable disconnected during the test. This is required in order to prevent the surge suppression circuitry, which is connected to surge ground, from being activated. Figure 7 - Dielectric Strength Testing 12 2007 RuggedCom Inc.
2.3 RS232 Console Port Wiring The RS232 port is used for configuring the unit. A straight-through serial cable with a DB-9 connector is required. There is no need to crossover the Transmit and Receive signals from the PC side since this has been done internally as is shown below.
3 Ethernet Ports 3.1 RJ11 Ethernet over VDSL Port 3.1.1 Overview The Ethernet over VDSL (EoVDSL) port on RS900L operates in pairs with one configured as the Master and the other as the Slave. In VDSL literature the terms Central Office (CO) or Line Termination (LT) are used interchangeably for the Master and the terms Customer Premise Equipment (CPE) or Network Termination (NT) are used interchangeably for the Slave. Configuration of Master or Slave mode is done through the RuggedSwitch Operating System.
3.1.2 Wiring VDSL typically operates over 2-wire CAT-3 wiring; however, other categorized or uncategorized twisted-pair wiring will work although the performance will vary depending on the distance and cable characteristics. It is important that the wiring used does not have any open leads (also known as bridged taps or drop-lines) along its length because this will impact performance by degrading the signal. 3.1.3 Configuration & Setup 1. Log into the RuggedSwitch Operating System. 2.
The unit can automatically select the best bit-rate based on current line conditions. If the line conditions degrade (reducing the SNR) but the unit is able to maintain the link, an alarm will be triggered to notify the user of the reduced SNR. If the line conditions degrade such that the unit is unable to maintain the current link, the unit will restart the scan process. NOTES: 1.
3.2 RJ45 Ethernet Ports The RS900L has several 10/100Base-TX ports that allow connection to standard Category 5 (CAT5) unshielded twisted-pair (UTP) cable with RJ45 male connectors. The RJ45 receptacles are directly connected to the chassis ground on the unit and can accept CAT-5 shielded twisted-pair (STP) cables. If shielded cables are used, care must be taken to ensure the shielded cables do not form a ground loop via the shield wire and the RJ45 receptacles at either end.
NOTE: RuggedCom does not recommend the use of copper cabling of any length for critical realtime substation automation applications. However, transient suppression circuitry is present on all copper ports to protect against damage from electrical transients and to ensure IEC 61850-3 and IEEE 1613 Class 1 conformance. This means that during the transient event communications errors or interruptions may occur but recovery is automatic.
3.3 Fiber Optic Ethernet Ports Depending on the order code of the product, the unit can be equipped with several different fiber optic ports. The Transmit (Tx) and Receive (Rx) connections of each port must be properly connected and matched for proper link and operation. The drawings in the following figures show each fiber optical connector style with a side and top view to allow the user to identify the proper cable connection orientation.
