Product Overview

This chapter provides physical and functional overviews of the ONS 15190 IP Transport Concentrator. It contains physical descriptions of the concentrator hardware and major components, and functional descriptions of the hardware-related features.

The Cisco ONS 15190 is a high performance IP transport management platform offering Internet service providers and greenfield IP operators carrier-class IP transport services within the point of presence (POP), regional metro, and metro access rings. Designed with support for OC-12/STM-4 and OC-48/STM-16, the Cisco ONS 15190 is a superior scaling and management solution for spatial reuse protocol (SRP) and packet over SONET (POS) networks, and is also a central management point.

As a complement to Cisco's Dynamic Packet Transport (DPT) line of SRP products, the Cisco ONS 15190 enables the creation of logical rings over physical star-based fiber topology for maximum performance and reliability. With reordering, insertion, or removal of nodes on live rings without service interruption, as well as automatic detection and connection of nodes, the Cisco ONS 15190 is in a position to best optimize the available ring bandwidth, deploy RPR/DPT rings, and protect against human errors.

ONS 15190 features include:

Ease of deployment—Automatically detects all attached nodes and creates logical rings over the star topology
Manageability—Allows remote arrangement of the ring for maximum utilization; nodes can be reordered or split into subrings with no interruption in service
Scalability—Allows a smooth scaling path by enabling the addition of nodes or Cisco ONS 15190 units to the ring with no service interruption and no fiber rewiring to existing nodes
Enhanced ring resiliency—The enhanced intelligent protection switching (E-IPS) mechanism bypasses failed nodes in RPR/DPT rings, thereby minimizing ring wraps; using the single ring recovery (SRR) protocol, nodes can be dual-homed to two Cisco ONS 15190 units, thereby ensuring ring connectivity in the event of a Cisco ONS 15190 failure; the SRR also protects the ring in the event of multiple failures on a single ring
POS protection—Supports automatic protection switching (APS) and multiplex switching protection (MSP) to self-heal POS link failures
Improved network serviceability—Monitors optical power, monitors SONET/SDH alarms and indications, and tracks packets
Improved security—Supports authentication, authorization, and accounting (AAA) using TACACS+, including central login database management capabilities.

The ONS 15190 provides a high-level of system redundancy, online insertion and removal (OIR), a 6-fan cooling unit, and system temperature monitoring. The unit can be configured and controlled locally via a RS-232C serial connection or remotely via Ethernet.

ONS 15190 overview information is presented in the following sections:

Physical and Functional Overviews

The ONS 15190 chassis contains 16 physical slots and a fan mechanism at the bottom.

Figure 1-1: ONS 15190 Front View

The ONS 15190 chassis can contain the following cards:

Power entry module (PEM)—The PEM slot contains up to two PEMs, each of which requires a -48V DC power source. One PEM is sufficient for operation of the unit; two are required for system redundancy.
Controller card—The controller slots are C1 and C2. One controller card is sufficient for operation of the unit; up to two cards can be used for complete redundancy.
Line cards—Eight line card slots (L1 to L8) support up to eight line cards. Two-port OC-12c/STM-4 and OC-48c/STM-16 line cards provide two connector pairs (Tx, Rx) each, which are used to connect nodes to the unit. Four-port OC-12c/STM-4 line cards provide four such connector pairs. bidirectional wavelength division multiplexing (BWDM) line cards provide two single connectors, each of which support bidirectional traffic.
Switch cards—Slots S1 to S5 can house up to five switch cards. For OC-12c/STM-4 operation using only two-port cards, one switch card is required; two cards can be used for 1+1 redundancy. When four-port line cards are used, five switch cards are required for normal use. For OC-48c/STM-16, four switch cards are required; five cards can be used for redundancy.
Fan tray —Six fans extend across the bottom of the unit (below the card slots) to cool the unit.

Power Entry Module Card

The PEM slot is the far left slot on the unit. This slot can hold either one or two PEM cards. Each card contains the following:

Power LED—Green when the power is on and red when there is a problem with the PEM.
Optional On/Off switch—Powers the module on and off.
-48V DC connector—Provides power to the system. Supplied power may be between -40 to -70V DC.

Figure 1-2: PEM Cards Front Panel

Controller Card

Slots titled C1 and C2 in the unit are for controller cards. One card is required; the second is for system redundancy.

Figure 1-3: Controller Card Front Panel

Three LED signals at the top of the controller card indicate the operational status of the card:

PWR—Green when the card is powered.
ACT—Indicates that the card is functioning properly. When the controller card is the active controller, this LED flashes at the same rate as all other cards in the unit (1 second on, 1 second off). When the controller card is on standby (for control redundancy), this LED flashes approximately four times slower than the other cards in the unit.
FAIL—Red when there is a problem with the card.

The RESET button can be used to reset the card.

The Ethernet connection is used to connect the unit to a LAN network. The Ethernet ports of both controller cards should be connected to a LAN network.

LINK LED—Indicates that the Ethernet link is active.
DATA LED—Indicates that the Ethernet connection is transmitting or receiving data.

The CONSOLE and MAINT (maintenance) connections are used to connect the unit to a local RS-232C cable in order to configure and control the ONS 15190:

CONSOLE—Controls the active controller card (even if the connection is to the redundant controller card).
MAINT—Controls only the controller card to which it is attached.

Note You can connect only to one of the CONSOLE ports at any one time because this port controls both controller cards.

Controller cards are OIR, and if a controller card fails, the second controller card takes over operation of the system automatically. The system is operable without a controller card, with the following limitations:

No configuration can be performed, including addition of line cards.

No system messages will be received.

AIS will not be mirrored.
Path trace will not be mirrored (when in transparent mode).
E-IPS and Autotrack options will not function.
Counters will be lost.
If switch cards are removed while four-port line cards are in use, the system can stop operating.

OC-12c/STM-4 and OC-48c/STM-16 Line Cards

Each line card contains either two or four ports. Two-port OC-12c/STM-4 and OC-48c/STM-16 line cards are used to connect two OC-12c/STM-4 or OC-48c/STM-16 connections, respectively, to the ONS 15190. Four-port OC-12c/STM-4 line cards can be used to connect up to four OC-12c/STM-4 connections each. Each port contains a pair of optical fiber connectors that are used to connect one transmit and one receive line from the connected node.

Two ONS 15190 units can operate in an "inner-outer" fiber topology so that the SRR protocol provides redundancy to maintain full connectivity in the event of a failure in one ONS 15190. In this scenario, the inner ring fibers are connected to one ONS 15190 unit, and the outer ring fibers are connected to the second unit, meaning that only half of an SRP node is connected to each ONS 15190 unit.

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

Each line card contains three LEDs (PWR, ACT, FAIL) to indicate the operational status of the card. (See the section "Controller Card".) When the line card is initialized, the ACT LED flashes very fast; when the card is operational, the ACT LED flashes at a constant rate of once per second in synchronization with the active controller card.

Warning Invisible laser radiation may be emitted from the aperture ports of single-mode line cards when no fiber cable is connected. Avoid exposure and do not stare into open apertures to avoid permanent eye damage.

Figure 1-4: OC-12/STM-4 Single-Mode Line Card Front Panel

Figure 1-5: OC-48c/STM-16 Single-Mode Line Card

Each port has five LEDs that indicate the status of the respective connection:

ACTIVE—Indicates that the port is part of an operational ring/connection.
CARRIER—Indicates that there is light in the specific receiving port.
RX PKT—Indicates that the line is actively receiving data.
A and B—Indicates whether the port is Receive Outer/Transmit Inner (A) or Transmit Outer/Receive Inner (B) for SRP.

BWDM Line Card

The (BWDM) line card is used to connect two bidirectional wavelength division multiplexing (WDM) fiber-optic connections.

Figure 1-6: Bidirectional WDM

Figure 1-7: OC-12/STM-4 BWDM Line Card Front Panel

In addition, each BWDM line card contains two ports. Each port contains one optical fiber connector that is used to connect one bidirectional line from the connected node. When connecting BWDM cards between ONS 15190 systems, port 1 of the BWDM card must be connected to port 2 of the second BWDM card and visa versa.

Each port has five associated LEDs which indicate the status of the respective connection:

ACTIVE—Indicates that the port is part of an operational ring/connection.
CARRIER—Indicates that there is light in the specific receiving port.
RX PKT—Indicates that the line is actively receiving data.
A and B—Indicates whether the port is Receive Outer/Transmit Inner (A) or Transmit Outer/Receive Inner (B) for SRP.

Switch Card

Up to five switch cards can be installed in the ONS 15190 unit. For OC-12c/ STM-4 operation with two-port line cards, one switch card is required, with a second card providing 1+1 redundancy. For OC-12c/STM-4 operation with four-port line cards, five switch cards are required for normal operation and complete system redundancy.

Note The ONS 15190 with four-port OC-12c/STM-4 line cards can be operated with only two switch cards; however system redundancy and use of a sniff node are only enabled when all five switch cards are operational. If the number of switch cards is less than five, a controller card must be active to ensure proper operation of the line cards.

For OC-48c/STM-16, four switch cards are required, with the fifth providing 4+1 redundancy. Each switch card contains three LEDs (PWR, ACT, FAIL) to indicate the operational status of the card. (See the section "Controller Card".) Switch cards are OIR and feature automatic fault detection and switch over with no data loss.

Figure 1-8: Switch Card Front Panel

Fan Tray

The fan tray located on the bottom of the ONS 15190 unit cools the unit during normal operation. The fan tray is OIR, and the system can function without the fan mechanism. Do not remove the fan tray for more than 5 minutes because the concentrator components can become over-heated.

The fan tray contains six fans. Operation of the system can continue almost indefinitely even if one of the fans is not operational. If any of the fans fail, a warning message appears on the screen connected to the control card. Have a spare fan tray available in the event of a fan failure.

By default, the system will continue operation as long as the cards' temperature remains below 167°F (75°C). If the temperature on any of the individual cards exceeds this temperature, the card stops operation. This temperature-protection mechanism can be changed via the command line interface (CLI) commands.

The temperature of any card can also be verified via the CLI, as shown in the following example:
