PORTswitch 900CP

This document provides comprehensive instructions for installing and configuring the PORTswitch 900CP module. The PORTswitch 900CP is a port-switchable, 16-port, ThinWire, 10Base2 Ethernet repeater that can be integrated into a DEChub 900 Multiswitch or operated as a standalone unit in a DEChub ONE or ONE-MX docking station.

Key aspects covered include:

• Module Description: Details the hardware, firmware, and management features, such as flexible port interconnection to internal LAN segments, per-port security (eavesdrop prevention and intrusion protection based on MAC addresses), upgradeable firmware via TFTP, and support for in-band SNMP and out-of-band management (SLIP) with various MIBs (e.g., RMON).
• Installation: Guides users through comparing power ratings, physically seating the module (which supports hot-swap), verifying initial LED operation, and connecting 10Base2 ThinWire cables.
• Configuration: Explains how to access the setup port via a serial connection to configure module parameters. This includes options to reset to factory defaults or current settings, display current configurations, set IP-related parameters (SNMP community, trap addresses, in-band/out-of-band IP addresses, BootP), dump error logs, and perform firmware upgrades (Downline Upgrade). Special emphasis is placed on not interrupting power during the firmware upgrade process.
• Removal: Provides steps for safely disconnecting cables and unseating the module.
• Problem Solving: Offers troubleshooting information using LED indicators to diagnose various module states and suggests corrective actions.
• Appendices: Contains detailed information on connector pin assignments, remote monitor (RMON) alarms and events, and product specifications (environmental, physical, and acoustical).
