Chapter 22 DLPs A500 to A599

DLP- A553 Upgrade DS1 or DS3-12 Cards in a 1:N or 1:1 Configuration to High-Density Electrical Cards

For 1:N protection groups where N = 2: On the A side, the protect card cannot be upgraded if any electrical cards are installed or preprovisioned in Slots 4, 5, or 6 (or Slots 12, 13, or 14 on the B side).

For 1:N protection groups where N = 1: On the A side, if the protect card is installed in Slot 3 and it protects a low-density card in Slot 1, the protect card cannot be upgraded if Slot 5 or 6 has an electrical card installed or preprovisioned. For the B side, if the protect card is installed in Slot 15 and it protects a low-density card in Slot 17, the protect card cannot be upgraded if Slot 12 or 13 has an electrical card installed or preprovisioned.

For 1:N protection groups where N = 1: On the A side, if the protect card is installed in Slot 3 and it protects a low-density card in Slot 2, the protect card cannot be upgraded if an electrical card is installed or preprovisioned in Slot 4. On the B side, if the protect card is installed in Slot 15 and it protects a low-density card in Slot 16, the protect card cannot be upgraded if an electrical card is installed or preprovisioned in Slot 14.

The following limitations apply to upgrading a working card after you have upgraded the protect card:

A working card in Slot 1 on the A side (Slot 17 on the B side) cannot be upgraded if an electrical card is installed or preprovisioned in Slot 5 or 6 (Slot 12 or 13 on the B side).

A working card in Slot 2 on the A side (Slot 16 on the B side) cannot be upgraded if an electrical card is installed or preprovisioned in Slot 4 (Slot 14 on the B side).

Step 4 In node view, double-click the current protect card. The card view appears.

Step 5 Make sure the current protect card is not active:

a.In card view, click the Maintenance > Protection tabs.

b.Select the protection group where the protect card resides.

Step 6 If the card status is Protect/Active, perform a switch so that the protect card becomes standby:

a.Click Switch.

b.Click Yes in the confirmation dialog box.

Step 7 Physically remove the card:

a.Open the card ejectors.

b.Slide the card out of the slot. This raises the IMPROPRMVL alarm, which will clear when the upgrade is complete.

Step 8 Right-click the Protect/Standby slot and change the low-density card to the high-density card:

a.Choose Change Card from the drop-down list.

b.Choose the new high-density card type from the Change to drop-down list.

c.Click OK.

Step 9 Physically insert the new high-density electrical card into the protect slot. Be sure to remove the plastic protective covers on rear of the card before installing the card.

a.Open the ejectors on the card.

b.Slide the card into the slot along the guide rails.

c.Close the ejectors.

Wait for the IMPROPRMVL alarm to clear and the card to become standby. For more information about LED behavior during the high-density card boot-up, see the "NTP-A17 Install the Electrical Cards" procedure on page 2-9.

Step 10 Because the low-density working card is now active, switch traffic away from the low-density card:

a.In node view, double-click the slot where the low-density card is installed.

ONS 15454 specifications

Cisco Systems ONS 15454 is a versatile optical networking platform designed to enable service providers and enterprises to deploy and manage robust optical networks efficiently. The ONS 15454 serves as a cornerstone in the evolution of transport networks, featuring various technologies that meet the increasing demand for bandwidth and service quality.

One of the standout features of the ONS 15454 is its support for multiple service types, including TDM, Ethernet, and Wavelength Division Multiplexing (WDM). This capability allows service providers to maximize network resources while delivering a wide range of services, from traditional voice to high-speed data and video.

The ONS 15454 leverages Dense Wavelength Division Multiplexing (DWDM) technology, enabling the transmission of multiple data streams over a single optical fiber. This effectively expands the network's capacity without the need for additional infrastructure, a crucial benefit in today's ever-growing data landscape. The system supports a variety of transponder modules, allowing for flexible scaling and seamless upgrades as bandwidth requirements increase.

Scalability is another key characteristic of the ONS 15454. With its modular architecture, it accommodates a range of interfaces and line cards, making it easier to tailor deployments to specific customer needs. This modularity not only facilitates upgrades but also simplifies maintenance, minimizing downtime and operational costs.

The platform also features advanced management capabilities through Cisco's Optical Network Management system. This allows for real-time monitoring, provisioning, and troubleshooting, ensuring network reliability and performance. The intuitive interface and comprehensive reporting tools enable operators to gain insights into network operations, improving decision-making processes.

Furthermore, the ONS 15454 is built to support optical layer protection features, enhancing network resilience. Technologies such as Automatic Protection Switching (APS) and Optical Supervisory Channel (OSC) ensure that connectivity is maintained even in the event of a failure, crucial for mission-critical applications.

In conclusion, the Cisco ONS 15454 is a powerful optical networking solution that combines flexibility, scalability, and advanced management features. Its support for various services and technologies positions it as an essential asset for organizations looking to build a future-proof network capable of handling increasing data traffic while maintaining high service standards.
