Carrier I-VU Server Recovery and Setup

This guide covers recovering and accessing legacy Carrier i-Vu servers when documentation is unavailable.

Understanding I-VU Server Architecture

Carrier i-Vu is built on Tridium Niagara AX or N4 framework. The server types include:

Model	Platform	Typical Use
i-Vu Pro	Niagara AX/N4	Enterprise server
i-Vu Link	Niagara AX	Building-level controller
i-Vu Open	Niagara N4	Open protocol server
CCN Router	Proprietary	Legacy Carrier Comfort Network bridge

Initial Assessment

Physical Inspection

1. Check model label - Usually on bottom or back panel
2. Identify ports - Ethernet, USB, serial, CCN bus
3. Note LED status - Power, network activity, fault indicators
4. Check for CompactFlash slot - Configuration may be stored on CF card

Power Requirements

• Most i-Vu devices use 24VAC (same as JACE controllers)
• Some rack-mount servers use standard 120VAC
• Verify power requirements before connecting

Network Access

Default Network Settings

Try these common default configurations:

Setting	Default Value
IP Address	192.168.1.100 or DHCP
Subnet Mask	255.255.255.0
HTTP Port	80 or 443
Platform Port	4911 (Niagara)

Connection Methods

Method 1: Direct Ethernet

1. Connect laptop directly to server Ethernet port
2. Set laptop to static IP in same subnet (e.g., 192.168.1.50)
3. Open browser to https://192.168.1.100
4. Try common default credentials (see below)

Method 2: Network Scan

1. Connect server to same network as your laptop
2. Use network scanning tool (Advanced IP Scanner, Angry IP Scanner)
3. Look for devices with ports 80, 443, or 4911 open
4. Niagara devices often show "Niagara" in HTTP banner

Method 3: Serial Console (if equipped)

1. Connect via RS-232 serial cable
2. Use terminal emulator (PuTTY, Tera Term)
3. Settings: 115200 baud, 8N1
4. May provide command-line access to network config

Default Credentials

Try these common factory defaults:

Username	Password	Notes
admin	admin	Most common
admin	password
admin	carrier	Carrier default
tridium	tridium	Niagara default
installer	installer
guest	guest	Limited access

Note: If credentials have been changed and are unknown, you may need to contact Carrier technical support or perform a factory reset (which may erase configuration).

Accessing Configuration

Web Interface

1. Navigate to https://[IP_ADDRESS]
2. Accept any certificate warnings (self-signed certs are common)
3. Log in with credentials
4. Navigate to Config > Station to view current setup

Workbench Access

1. Open Niagara Workbench (matching version - AX or N4)
2. File > Open > Open Platform
3. Enter IP address and port 4911
4. Log in with platform credentials
5. Open the station from the platform

Database Backup

Once accessed, immediately create a backup:

1. In Workbench: File > Backup
2. Save .dist file to secure location
3. Also export any graphics and schedules separately

Common Issues

Server Won't Boot

• Check power LED - solid green indicates power OK
• Try different power supply (24VAC transformers can fail)
• Listen for HDD/fan activity
• CompactFlash cards can corrupt - try removing and reseating

No Network Connectivity

• Verify Ethernet link LED on server and switch
• Try different cable
• Connect directly (eliminate switch issues)
• Check if network port is disabled in software

Forgotten Credentials

Options in order of preference:

1. Contact Carrier technical support with device serial number
2. Check with the installing contractor (credentials may be documented)
3. Factory reset (WARNING: loses all configuration)
4. Attempt password recovery via Tridium if you have the platform license

Evaluating Usability

Worth Recovering If:

• Hardware passes POST and boots normally
• Niagara license is valid (check license expiration)
• Contains programming for existing equipment
• Newer firmware can be applied

Consider Replacement If:

• Running Niagara AX 3.5 or older (security vulnerabilities)
• License has expired and can't be transferred
• Hardware is unreliable (repeated failures)
• Integration requirements exceed device capabilities

Next Steps After Recovery

1. Document everything - Credentials, IP addresses, point counts
2. Update firmware - If significantly outdated
3. Review security - Change default passwords, disable unused services
4. Create backups - Station backup, graphics export, database dump
5. Evaluate migration - May be time to move to newer platform
