3. Redundant Power Supplies

With all monitoring applications, redundant power is a must. Your monitoring devices have to be the most reliable elements in your network if they are to protect your revenue-generating equipment.

Look for a proxy device with dual power inputs. If one power supply fails, you'll have another on reserve-ensuring that you have continued visibility of mission-critical equipment.

4. Extra Features

The best quality proxy devices will support additional features for managing your remote sites. This saves money, because you don't need to buy extra equipment, and it gives you a simple, one-platform solution for managing every part of your remote site.

Some of the extra features you should look for in a top-quality proxy device include:

Terminal Server Functionality: Your proxy device can host remote Telnet sessions to interface with the craft ports of on-site telephony equipment like PBXs, switches, and routers. This gives you easy LAN access for configuring and rebooting equipment, saving a fortune in windshield time.

Ping Alarms: Your proxy device can also make sure that your IP network elements are operational, by regularly pinging their IP addresses. If a network device fails to respond to a ping, the proxy device will immediately send an SNMP trap to the SNMP manager.

Protocol Mediation: You may have additional remote site equipment that supports a classic telemetry protocol such as TBOS or TABS. Alarm output from these devices can be mediated to SNMP traps.
