Installation

Unpack and inspect contents. Place in a well-ventilated rack or shelf.

Connect power: Attach AC power cord to power supply and outlet.
Connect console: Use serial cable from console port to PC for initial setup.
Connect network cables: Attach Ethernet cables to LAN/WAN ports as required.
Power on the router.

WARNING! Router may be heavy; use proper lifting techniques. Ensure adequate ventilation to prevent overheating.

First-Time Setup

Power on router; access via console connection.

Access CLI: Use terminal emulator (e.g., PuTTY) at 9600 baud.
Run setup utility: Follow prompts to configure basic parameters (hostname, passwords, IP).
Configure interfaces: Assign IP addresses to LAN/WAN ports.
Save configuration: Use 'copy running-config startup-config'.

CAUTION! Secure physical access; set strong passwords during initial configuration.

Controls and Settings

Access configuration via CLI or web interface (if enabled). Front Panel: POWER, STATUS LEDs, RESET button.

CLI Commands: enable, configure terminal, interface, show running-config, copy running-config startup-config.

Basic Settings: Hostname, IP addresses, routing protocols (OSPF, EIGRP), VLAN configuration. Security: Access control lists (ACLs), firewall policies, VPN configuration. QoS: Priority queuing for voice/video traffic. Management: SNMP, syslog, SSH for remote access.

Connecting Devices

LAN: Ethernet cables to switch or end devices. WAN: Serial or DSL cables to service provider. Console: Serial to PC for management.

Turn off router before connecting cables if possible.
Match cable types to ports (e.g., RJ-45 for Ethernet, DB-9 for console).
Verify link LEDs after connection.

Tip: Label cables for easier management and troubleshooting.

Managing Network Services

Supports routing, switching, security, and voice services.

Routing: Configure static routes or dynamic protocols (OSPF, BGP).
Switching: Create VLANs and assign ports.
Security: Apply ACLs, set up IPSec VPN tunnels.
Voice: Configure dial peers and QoS for VoIP.
Monitoring: Use 'show' commands to verify status and performance.
Backup: Regularly backup configuration to TFTP server or USB.
Upgrade: Use USB or TFTP to update IOS software.
Restore: Reload configuration from backup if needed.

WARNING! Save configuration before upgrades or major changes. Reload may be required.

Security Features

Firewall: Stateful inspection via Cisco IOS Firewall. VPN: Site-to-site and remote access IPSec VPNs. Access Control: Standard and extended ACLs. Authentication: AAA support with RADIUS/TACACS+.

Care & Maintenance

Power off before cleaning. Use compressed air to remove dust from vents. Keep firmware updated.

CAUTION! Do not block ventilation openings. Avoid liquid exposure.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No power	Power cord/outlet	Check power cord connection; verify outlet function; check power supply.
No network connectivity	Cable/config	Verify cable connections; check interface status with 'show interfaces'; verify IP configuration.
Console not responding	Cable/settings	Check serial cable; verify terminal settings (9600 baud, 8N1).
VPN not establishing	Configuration/ISP	Verify IPSec configuration; check for NAT/firewall issues; ensure proper routing.
High CPU usage	Processes/traffic	Use 'show processes cpu' to identify culprit; adjust QoS or ACLs if needed.

Reset: Use RESET button for 10 seconds to restore factory defaults (erases configuration).
