Extension shelves

Overview

An extension shelf is a virtual object that is modeled in the NFM-P as a shelf object. It can represent a variety of equipment connected to the NE by cables connected to uplink ports. This section describes the types of extension shelves supported by the NFM-P.

Ethernet satellite shelf

An Ethernet satellite shelf is a breakout box attached to a router that provides equipment support for additional gigabit Ethernet ports. These breakout boxes are modeled as virtual shelves on the host NE in the NFM-P. See To create a satellite shelf for information about creating a satellite shelf on an NE. Each breakout box is connected to an NE through uplink ports; see To configure satellite shelf uplink port topology for information about configuring the uplink.

You can specify the satellite file transfer protocol to be used for the boot process when transferring boot images and configuration files from the 7x50 host to the Ethernet satellite. See To configure satellite file transfer for more information.

TDM satellite shelf

A TDM satellite shelf is a separate TDM chassis attached to a router that provides additional TDM ports. See To create a satellite shelf for information about creating a satellite shelf on an NE. Each chassis is connected to an NE through uplink ports; see To configure satellite shelf uplink port topology for information about configuring the uplink.

Software upgrade

You can upgrade the software on an optical extension shelf using the NFM-P. To perform an upgrade, you must associate the shelf with a software repository, then perform a reboot upgrade. See To perform a software upgrade on an extension shelf for information about upgrading system software on a TDM satellite shelf.
