1 Introduction
This guide describes how to install and manage the 30-10022-01 loop switch.
Overview
The 30-10022-01 loop switch is a 12-port, speed agile switch. Enclosed in a 1U, half-rack form factor
enclosure, the switch is controlled by firmware loaded into the on-board flash memory. The switch is
designed as a central interconnect following the ANSI FC-AL standard. Devices are connected to the
switch through Small Form-factor Pluggable (SFP) transceivers and cables.
Each port independently supports 1 or 2 Gb/s of Fibre Channel bandwidth. Automatic port
configuration allows individual port access using automatic speed detection to connect devices based
on their supported speed. Smart synchronization validates proper initialization, checking signal
integrity and certain errors, such as OS and CRC, before allowing access to other Fibre Channel
devices. During normal operational when a change notification (LIP) is sent, the Bad Device
Recovery feature detects non-Fibre Channel compliant devices and removes them from participation.
Further validation continues to either bypass the port or allow access back into the Fibre Channel
network. Proper device notification is provided through the switch’s event log.
The switch also features automatic-configuration capability, which allows for IP address assignment
using DHCP- compatible networks. Once the switch is operational, complete switch configuration and
management is available through the intuitive, graphical-based Web Manager interface. In addition,
the switch features granular change notification management, retained system configuration
parameters, and a Command Line Interface (CLI).
