Chapter 1 Cisco ONS 15310-MA SDH Shelf Assembly Hardware

Shelf Temperature

To install redundant power feeds, use four power cables and one ground cable. For a single power feed, only two power cables and one ground cable are required. A 1-inch (minimum) wide copper braid is required to ground the ONS 15310-MA SDH outside plant (OSP) cabinet and is recommended for indoor installations. For example, central office.Use #12 AWG power cables and a #6 AWG ground cable and, to ensure circuit overcurrent protection, use a conductor with low impedance. The conductor must have the capability to safely conduct any fault current that might be imposed. Do not use aluminum conductors.

Note The DC power Battery Return (BR) or positive terminal, must be grounded at the source end (power feed or DC mains power end). The DC power BR input terminal of the ONS 15xxx is not connected to the equipment frame (chassis).

Caution If the system loses power or the 15310E-CTX-K9 card is reset, you must reset the ONS 15310-MA SDH clock unless the node has been previously provisioned to use Simple Network Time Protocol (SNTP). SNTP updates the clock over the LAN.

1.7 Shelf Temperature

The ONS 15310-MA SDH chassis temperature is displayed in the Shelf view > Provisioning > General

>Voltage/Temperature pane in CTC. The temperature of the shelf (in degrees Celsius) is displayed in the Temperature area of the Voltage/Temperature pane.

Note For ONS 15310-MA SDH chassis, voltage monitoring is not performed.

1.8 Cable Description and Installation

This section describes fiber-optic, E3 (coaxial), E1 (64-pin Champ), UDC, and twisted-pair cables.

1.8.1 Cabling Types

The following types of cables are used with the ONS 15310-MA SDH:

Optical cables: The STM1/4/16 signals operate over fiber spans through SFP optics, including intermediate-reach (IR) and long-reach (LR) SFPs. Specification references can be found for the interface in ITU G.957 and Telcordia GR-253. See the “1.8.2 Fiber Cable Installation” section on page 1-13for more information. Make sure the fiber cables do not bend excessively; maintaining a proper bend radius prevents damage to the optical cable.

E1 cables: E1 cables (shielded, twisted-pair) connect to the electrical ports at the rear of the shelf assembly using Champ cable connectors. E1 cables carry E1 traffic to and from the ONS 15310-MA SDH. The ONS 15310-MA SDH supports up to three transmit and three receive Champ-64 connectors on each side of the shelf assembly, for a maximum of 63 E1 signals per side of the shelf, 28+28+7

A compatible E1 cable is available from Lorom Industrial Co., LTD.

15310-MA specifications

Cisco Systems has established itself as a leader in the networking domain, offering a wide array of solutions to meet the needs of modern businesses. Among its impressive product lineup are the Cisco 15310-CL and 15310-MA routers, designed to provide advanced network performance and reliability.

The Cisco 15310-CL is a versatile platform that primarily serves as a carrier-class router aimed at supporting high-speed data and voice services. It is built to handle the demands of large enterprises and service providers, offering a robust design that ensures maximum uptime and performance. One of its standout features is its modular architecture, which enables users to customize their configurations based on specific application needs. This scalability allows for future expansion without the need for a complete hardware overhaul.

Key technologies integrated into the Cisco 15310-CL include high-density Ethernet interfaces and a comprehensive suite of Layer 2 and Layer 3 protocol support. The device is capable of supporting multiple types of connections, including TDM, ATM, and Ethernet. This flexibility makes it an ideal choice for organizations that require seamless migration between various service types. Moreover, with features such as MPLS (Multiprotocol Label Switching) support and advanced Quality of Service (QoS) mechanisms, the router ensures that critical applications receive the necessary bandwidth and low latency required for optimal performance.

In contrast, the Cisco 15310-MA focuses on access solutions, providing a cost-effective entry point for businesses looking to enhance their network capabilities. It is well-suited for smaller offices or branch locations that need reliable connectivity without the expense and complexity associated with larger systems. The device supports a range of access methods and provides essential features like firewall capabilities, VPN support, and comprehensive security measures to protect sensitive data.

Both models benefit from Cisco's commitment to security and manageability, offering features like enhanced encryption protocols and user authentication mechanisms that help safeguard networks against threats. Additionally, they can be managed through Cisco’s intuitive software tools, simplifying configuration and monitoring tasks for IT administrators.

The Cisco 15310-CL and 15310-MA are ideal solutions for businesses seeking to enhance their network infrastructure, ensuring firms can keep pace with evolving technology demands while maintaining a focus on security and performance. Their combination of advanced features, modular capabilities, and robust support makes them valuable assets in the networking landscape.
