Product Overview

This chapter provides physical and functional overviews of the Cisco ONS 15194 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 15194 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-48/STM-16, the Cisco ONS 15194 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 15194 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 15194 is in a position to best optimize the available ring bandwidth, deploy RPR/DPT rings, and protect against human errors.

ONS 15194 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 15194s to the ring with no service interruption and no fiber rewiring to existing nodes
Data Statistics—Performs traffic monitoring according to both interface and node. A history of the data rate is saved for each 15-minute interval, facilitating monitoring of chronological bandwidth-use trends.
Performance Monitoring—Standard SONET/SDH performance monitoring parameters indicate the condition of the data lines and provide the ability to access up to 96 15-minute data intervals.
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 15194s, thereby ensuring ring connectivity in the event of a Cisco ONS 15194 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 15194 provides a high-level of system redundancy, online insertion and removal (OIR), a 6-fan cooling tray, and system temperature monitoring. The ONS 15194 can be configured and controlled locally via a RS-232C serial connection or remotely via Ethernet.

ONS 15194 overview information is presented in the following sections:

Physical and Functional Overviews

The ONS 15194 chassis contains 16 physical slots and a fan mechanism at the bottom.

Figure 1-1: ONS 15194 Front View

The ONS 15194 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 ONS 15194; two are required for system redundancy.

Controller card—The controller slots are C1 and C2. One controller card is sufficient for operation of the ONS 15194; two cards can be used for complete redundancy.

Line cards—Eight line card slots (L1 to L8). Each OC-48c/STM-16 line card provides eight connector pairs (Tx, Rx), which are used to connect nodes to the ONS 15194.

Switch cards—Slots S1 to S5 can house up to five switch cards which all must be used for proper ONS 15194 operation.

Fan tray —Six fans extend across the bottom of the ONS 15194 (below the card slots) to cool the system.

Power Entry Module Card

The PEM slot is the far left slot on the ONS 15194. 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.

On/Off switch—Powers the module on and off.

-48V DC connector—Provides power to the ONS 15194. Supplied power may be between -40 to -70V DC.

Figure 1-2: PEM Card Front Panel

Controller Card

Slots titled C1 and C2 ONS 15194 front panel 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 ONS 15194 (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 ONS 15194.

FAIL—Red when there is a problem with the card.

The RESET button can be used to reset the card.

The Ethernet port is used to connect the ONS 15194 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) ports are used to connect the ONS 15194 to a local RS-232C cable in order to configure and control the ONS 15194:

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

Note The MAINT port should only be used for password recovery (see "Forgotten Password" in "Configuring the ONS 15194") or entering the boot system if the the software application cannot be booted.

Caution Do not leave the UART password key plugged into the MAINT port. In addition to being a security hazard, the software will not reload and boot correctly.

Two PCMCIA slots, supporting ATA Flash memory disk cards, exist on each of the controller cards. These slots are referred to as disk0 or disk1 in the management CLI. Files, such as image and configuration, can be copied between tehse disks and other system devices, such as the internal Flash memory.

Note You cannot boot the ONS 15194 from a PCMCIA disk, and the the ONS 15194 cannot access a configuration file on the PCMCIA disks.

Controller cards support online insertion and removal (OIR); therefore, if the active controller card fails or is removed, the second controller card automatically takes over operation of the ONS 15194. You should always have at least one controller card operating in the ONS 15194, although, the removal of both controller cards does not impact existing traffic flow. If there is no operational controller card, the management, automatic configuration and protection functionalities are disabled.

Line Cards

Each line card contains eight optical interfaces to connect up to eight OC-48c/STM-16 connections. Each interface contains a pair of optical fiber connectors that are used to connect one transmit and one receive line from the connected node. The software references each interface in ascending order (1 to 8) according its location on the card from top to bottom .

Each line card contains three LEDs (PWR, ACT, FAIL) to indicate the operational status of the card. (See the section "Controller Card.") While the line card is being initialized, the ACT LED flashes rapidly; thereafter, 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-48c/STM-16 Line Card

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

MOD—Indicates the status of the connection as described in Table 1-1:

Table 1-1: MOD LED Indications

Node Type	LED Status	LED Color
None	Off	NA
SRP	On— Defined node is connected to a ring Blink—Defined node is not connected to a ring	Green—Local A interface, connected to B side of connected device Amber—Local B interface, connected to A side of connected device
SRP-inner SRP-outer	On—Defined node is connected to a ring Blink—Defined node is not connected to a ring	Green—Outer node, Rx is connected to B side of connected device Amber—Inner node, Rx is connected to A side of connected device
APS	On—Defined node is connected to another APS or POS node and is the selected APS link Blink—Defined node is not connected to another APS or POS node	Green—Working link Amber—Protection link
POS	On—Defined node is connected to another APS or POS node Blink—Defined node is not connected to another APS or POS node	Green

PKT—Indicates that the line is actively receiving data.The blinking rate is correlated with the received data packet.
CAR—Indicates that the interface is connected to a peer (an optical signal is being received).

Switch Card

Five switch cards must be installed in the ONS 15194 for normal operation and complete system redundancy.

The switch cards function in a 4+1 redundancy scheme, where four cards are required for basic ONS 15194 functionality and the fifth card provides redundancy if a switch card fails or is removed. Each switch card contains three LEDs (PWR, ACT, FAIL) to indicate the operational status of the card. (See the section "Controller Card.") Switch cards support OIR and feature automatic fault detection and switch over with no data loss.

Figure 1-5: Switch Card Front Panel

Fan Tray

The fan tray located on the bottom of the ONS 15194 cools the system during normal operation. The fan tray supports OIR, and the ONS 15194 can function without the fan mechanism. Do not remove the fan tray for more than 2 minutes because the concentrator components can become over-heated.

The fan tray contains six fans. Operation of the ONS 15194 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 ONS 15194 will continue operation as long as the card 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:
