Installing the ONS 15190

The procedures for installing the ONS 15190 and contains the following sections:

After you prepare the area for installation and verify that all equipment is present, you can proceed with the ONS 15190 installation.

Warning To prevent ESD damange, use an ESD wrist strap when you unpack and install system components.

Rack-Mount Installation

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.

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 At the location of each of the eight marked holes, 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).

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. Open each 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.

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

Step 3 Gently pull the card out of the slot.

Note Line cards can only be inserted into slots L1 to L8; switch cards can only be inserted into slots S1 to S5; controller cards can only be inserted into slots C1 or C2.

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.

Powering Up the System

When all necessary cards are installed into the chassis, connect the PEM to an electrical power source as follows:

Step 1 If the optional power supply unit is used, follow the instructions in the chapter "Power Supply Unit". If batteries are used, connect each of the two 48V DC cables to one of the two PEM cards, respectively.

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

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

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

Step 5 Line and switch cards—PWR LED should be lit. 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 be lit for 3 to 4 seconds, after which it should turn off.

Cable Connections

Cable connections are presented in the following sections:

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 the 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 system is provided with the fan tray 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 can be replaced in-service. However, it is recommended not to 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.
