Installing the ONS 15190

Note You must install the ONS 15190 in a rack. The ONS 15190 is not designed to be installed as a shelf-mounted or a free-standing system. If you are using the optionally provided power supply unit, it must also be rack mounted as described in "Power Supply Unit".

To install the ONS 15190 chassis into a rack mount, do the following:

Step 1 Open the rack-mount installation kit containing the paper stencil and eight nuts, bolts, and washers.

Step 2 Unfold the stencil and place it on the rack at the location where the ONS 15190 chassis will be installed. Line up the marked holes of the stencil with the eight holes in the rack.

Step 3 Insert a nut from the back of the rack toward the front (so that the bolt can be screwed into the nut from the front of the rack) at the location of each of the eight marked holes.

Step 4 Lift the ONS 15190 up to the location of the nuts and have a second person screw in two of the bolts (one on each side) with the washers placed between the bolt and the ONS 15190 panel.

Step 5 When the unit is in place with one bolt on each side, screw in the other six bolts to secure the chassis on the rack.

Inserting and Removing ONS 15190 Components

When the chassis is secure in the rack, you can install the remaining line and switch cards into the unit. The possible cards and their respective slots in the ONS 15190 chassis are outlined following:

Card Type	ONS 15190 Chassis Slots
Line cards: OC-12c/STM-4 2 port and 4 port, OC-48c/STM-16, BWDM	L1 to L8
Switch cards	S1 to S5
Controller cards	C1, C2
PEM cards	PEM

Inserting Cards

Open one card from its original packing. Keep unused cards in their original packing until use. Remove the blank card from the slot where the card is to be inserted and insert the card into the empty slot.

To insert a card into the chassis, do the following:

Step 1 Gently push the card into the slot until it is inserted into the backplane.

Step 2 Press inward on the two black handles, toward the center of the card, to lock the card in place.

Step 3 Screw the card in place on the top and bottom.

Continue to install all necessary line and switch cards into the chassis. Leave blank cards in any unused slots.

Note Make sure that all cards are inserted correctly because partially inserted card may cause unexpected behavior.

Removing Cards

To remove a card from the chassis, do the following:

Step 1 Unscrew the card from the chassis (one screw each on the top and bottom of the card).

Step 2 Press outward on the two black handles, toward the top and bottom of the card, respectively.

Step 3 Gently pull the card out of the slot.

Note Store any unused cards in their original packing.

Powering Up the System

When all necessary cards are installed into the chassis, power up the system as follows:

Step 1 Connect one or both PEM cards to an electrical power source. This may be the optional power supply unit or any DC power source.

Step 2 Power up each of the PEM cards using the On/Off switch located on the card.

Step 3 The PWR LED should go on (green) immediately. If the PEM has no On/Off switch, the PWR LED turns on when the PEM is connected to a power source.

Step 4 Controller card—PWR LED should be on. If it is not on, verify that there is power to the system. Initially, the FAIL LED will be on. Approximately 30 seconds after power up, the FAIL LED should turn off. The ACT LED should begin to flash once per second. The standby controller card ACT LED should flash once per 3 seconds.

Step 5 Line and switch cards—PWR LED should go on. The ACT LED should flash fast for 3 to 4 seconds and then, as it becomes synchronized with the active controller card, it should flash once per second. The FAIL LED will initially go on for 3 to 4 seconds, after which it should turn off.

Cable Connections

Cable connections are presented in the following sections:

Fiber-Optic Cable Connections

Fiber-optic cable connections depend on the type of device being connected and the configuration of the ONS 15190. Possible scenarios are presented in the following sections:

SRP Node Connected to Single ONS 15190 Unit
Router Connectivity to Two Redundant ONS 15190 Units
POS and APS Connections

Note OC-12/STM-4 nodes or line cards cannot be connected to OC-48/STM-16 nodes or line cards.

When a node is correctly connected, the CARRIER LED for the respective port on the line card should go on. Similarly, there should be indication of the connection on the node side.

SRP Node Connected to Single ONS 15190 Unit

Connect each SRP/DPT node to two separate ports using two pairs of fiber-optic cables, as shown in Figure 4-1 and Figure 4-2. Two SRP/DPT nodes can be connected to each 4-port line card. For optimal redundancy, connect each side of an SRP node to a port on a different line card; for 2-port cards, do not connect two A ports (or two B ports) to the same line card.

Figure 4-1: Router Connectivity to 2-Port Line Card

Figure 4-2: Router Connectivity to 4-Port Line Card

SRP Node Connected to Two Redundant ONS 15190 Units

To connect an SRP node to two redundant ONS 15190 units, all the inner fibers of the SRP ring must be connected to one ONS 15190 unit, and all the outer fibers of the SRP ring must be connected to the second ONS 15190 unit. This means that the Tx/Rx connector pair in the node will be connected to different ONS 15190 units. Connect both inner fibers of a node to the same connector pair in one ONS 15190 unit and both outer fibers of the node to the same connector pair in a second ONS 15190 unit as shown in Figure 4-3.

Note In order for two ONS 15190 units to work together and provide system redundancy, all routers/devices in the ring must support SRR. SRR is supported in IOS Release 12.0(16)S for OC-48/STM-16.

POS and APS Connections

Connect each POS node to a single port. Connect automatic protection switching (APS) nodes to two separate ports, one for working and one for protection. The working and protection links for the ONS 15190 must correspond to the working and protection connections on the device.

BWDM Cable Connections

BWDM cards in different ONS 15190 units are connected to one another by connecting a pair of single fiber-optic cables between them. Port 1 in the first card is connected to port 2 in the second card and visa versa. Each fiber connected to a BWDM line card carries bidirectional traffic.

Ethernet Cable Connection s

Connect Ethernet cables between a hub/switch and the Ethernet connector on both the active and standby controller cards. Both controller cards should be connected to a hub. They can be connected to the same or different hubs. When correctly connected, the LINK LEDs should be on. The DATA LED indicates that there is information being passed on the line.

Serial Cable Connections

Note A direct serial connection to the active controller card must be used to configure the networking parameters of the ONS 15190 before it can be accessed via Ethernet. See "Configuring Network Parameters" in the chapter "Configuring the ONS 15190".

Connect the RS-232C serial cable between the CONSOLE connector on one of the controller cards and the COM port on your PC. The CONSOLE port controls the active controller card in the system, even if it is connected via the standby controller card. The MAINT connector is used for maintenance to a particular controller card and does not need to be continuously connected.

The default RS-232C connection parameters are 9600 bps, no parity, and no flow control.

Note You may only connect to one of the controller cards via its CONSOLE port at any one time.

Fan Tray Replacement

The fan tray is factory installed. If it is necessary to replace a faulty fan tray, do the following:

Step 1 Unscrew all screws holding the fan tray in the bottom of the unit.

Step 2 Gently pull the tray out of the chassis.

Step 3 Slide the replacement fan tray into place and replace the screws.

The fan tray is OIR.

Caution Do not leave the fan tray out of the unit for more than 5 minutes while the unit is operational so that system components do not become over-heated.
