FR-2RU-10-2	Rev. N

1. Product overview

The FR-2RU-10-2, hereafter called "sub-rack", is a compact sub-rack frame, providing space for up to 10 Flashlink modules of any combination, in addition to two fixed positions for power supply modules.

The sub-rack features maximum flexibility as every module comes with a suitable backplane module, which takes up n x 7TE spacing. This means that any combination of all modules can be fitted into the sub-rack, or expanded / rebuilt in the future, when other functionality is needed. Each sub-rack has an address setting available through DIPswitches on the rear, for use in combination with the GYDA-SC System Controller card.

The Flashlink system is built on a low-power consumption philosophy where no fans are needed. This saves the user from fan replacements, fan cleaning and fan filter kits.

Power consumption

The current draw in the Flashlink frame is limited by the power supplies. Overloading the power supplies will cause the power units to malfunction. Please read chapter 2.4 for further details!

Heat dissipation

The heat dissipation is based on convection, and it is therefore very important not to block the warm air exhaust on the top.

Our guideline is that for every 200W of dissipated power, 1RU of open rack space is needed above the uppermost frame for hot air exhaust.

2.2 Front view

The front view of the sub-rack shows status LEDs for each module that is included in the sub-rack + two green LEDs for the power supply modules.

Figure 1: LEDs in front of the Flashlink sub-rack.

The uppermost LED of each module card is a "general status" LED.

-Green light means that the card is OK.

-Red light means that the card is faulty.

-No light means that the power is not switched on.

The meaning of each LED on the module cards is described in their respective manuals.

2.3 Rear view

Figure 2 shows an example of a fully equipped Flashlink sub-rack, seen from the rear side.

To the left is the connector module for the power supply delivered with the sub-rack. The other connector modules are described in their respective user manuals.

2.4 Power consumption

The current draw in the Flashlink frame is limited by the power supplies. Overloading the power supplies will cause the power units to malfunction.

The maximum power limits are as followed:

Flashlink frame with the PSU 16653 PWR-AC-75W:

+5V	-	45W
+15V	-	15W
-15V	-	15W

Flashlink frame with the PSU 11374 PWR-AC15/15/5/5V:

+5V	-	30W
+15V	-	15W
-15V	-	15W

The sum of power for all cards on each rail must not be higher than the above listed limits. The power consumption for each of the power supply rails is found in the user manual for each Flashlink card, as this is not the same for all Flashlink cards.

The power supplies do not support load sharing. Hence, a second PSU in the frame does not increase the maximum power limits for the system.

3. Configuration

3.1 Address setting on each sub-rack

Each sub-rack can be assigned an address through the DIP-switches on the rear. Maximum 8 sub-rack addresses are available.

This address setting only applies when the sub-rack is used in combination with a GYDA-SC Rack System Controller.

If you have more than 8 sub-racks together, you need several GYDA-SC Rack System Controller cards.

In order to ensure proper operation of the system, it is important that no sub-racks controlled by the same GYDA-SC Rack System Controller card have the same address set.

Reset the sub-rack after reconfiguring the sub-rack system, by turning the power off and on again.

The setting of the address of a sub-rack is as follows:

1 0

0 means switch to the right (OFF)

1 means switch to the left (ON)

SW 4	SW 2	SW 1	Address
OFF	OFF	OFF	0
OFF	OFF	ON	1
OFF	ON	OFF	2
OFF	ON	ON	3
ON	OFF	OFF	4
ON	OFF	ON	5
ON	ON	OFF	6
ON	ON	ON	7

Default address is 0.

The GYDA-SC Rack System Controller automatically detects the position of the cards within each sub-rack.

More detailed information on the RS-422 configuration can be found in a separate document and at our web site: http://www.nevion.com/

4 Connections

4.1 Power connection

Figure 3 shows the power connections of the sub-rack as well as the RS-422 connections and the DIP-switches for address setting of the sub-rack.

Figure 3: Connector module for the power supply.

AC: Connect mains to the sub-rack with a mains cord with an IEC 320 connector. DC: Connect the DB9 male connector from the external DC power supply to the main unit. Tighten the screws to ensure a proper contact. The DC inputs have the same function; the left input (DC1) is for the left power module when seen from the rear and DC2 is for the right power module when seen from the rear.

4.1.1 Pin-out DC1 and DC2 (DB9)

The maximum current drawn from each pin of the DB9 connector is 2,5A.

Pin #1	GND for DC
Pin #2	+5V	Output, Max. current: 6A
Pin #3	Relay	GPI Output, Normally Open
Pin #4	+15V	Output, Max. current: 1A
Pin #5	Positive part of 48VDC supply	Input
Pin #6	-5V	Output, Max. current: 1A
Pin #7	Relay	GPI Output, Normally Open
Pin #8	-15V	Output, Max. current: 1A
Pin #9	Negative part of 48VDC supply	Input

Pin 1, 2, 4, 6 and 8 are common to both DC1 and DC2. (I.e. they are physically connected).

A green LED will light on the front when the power supply is in operation.

4.1.2 GPI Power Supply Status outputs

The GPI module status outputs can be used for wiring up alarms for third party control systems.

FR-2RU-10-2	Rev. N

In case of power failure, pins 3 and 7 will be physically connected (low impedance), otherwise the connection between pins 3 and 7 will be high impedance.

4.2 RS-422 connection

At the rear end of the sub-rack is an RS-422 bus. When used in combination with the GYDA-SC Rack System Controller, up to 8 sub-racks can be controlled. On the rear end of the sub-rack are DIP-switches where each sub-rack can be assigned its own address (see figure 3).

The RS-422 interfaces are shown in figure 3.

4.2.1 Pin-out RS-422 (RJ45)

Pin #1	Rx A (+)
Pin #2	Rx B (-)
Pin #3	Tx A (+)
Pin #4	Reserved
Pin #5	Reserved
Pin #6	Tx B (-)
Pin #7	Not Connected
Pin #8	Not Connected
	Figure 4: RS-422 pin-out.

4.2.2 Connecting several sub-racks together

Several sub-racks can be connected to each other through the RS-422 ports on the rear of each sub-rack.

One GYDA-SC controller can control maximum 8 sub-racks.

You start with the sub-rack containing the GYDA-SC Rack System Controller, and use 1 RS-422 port to loop through to the next.

The last sub-rack connected must be terminated with 110 in order to ensure proper operation. The other port of the rack containing the GYDA-SC controller must be left open, and cannot be connected to other sub-racks.

Figure 5 shows an example of how to connect 8 sub-racks together as seen from the rear end. By using the RS-422 interface at the GYDA-SC controller card, we control 8 sub-racks via one RS-422 bus.
