Source: Knox KeySecure Installation Manual (Revised Edition) Subject: Standard Rectangular Mounting (Type 3B)
The manual dedicates 12 pages to network bonding because misconfiguration leads to 85% of support calls. For a "hot" (active-active) setup:
Command sequence:
configure terminal
interface bond0
bond mode 4 (802.3ad)
bond slave eth1
bond slave eth2
ip address 192.168.10.10/24
no shutdown
exit
write memory
Common mistake: Forgetting to set the same MTU (1500 default) on both slaves. Use show interface bond0 to verify. knox keysecure 3b installation manual hot
If the bond fails to come up: Check your switch port channel configuration. The KeySecure 3B requires LACP (Active mode). Passive LACP will produce a "hot standby" error.
Many users skip the rail adjustment verification. The static rails for the KeySecure 3B have a locking mechanism that must audibly click. A loose mount leads to vibration, which loosens internal PCIe HSM cards—a recipe for intermittent "hot" failures.

The rear panel of the 3B has a specific order for first boot:
| Port Label | Purpose | "Hot" Tip | |------------|---------|------------| | PSU0 & PSU1 | Redundant power | Connect both to separate circuits. Do not use a single PDU. | | CONSOLE | Serial (115200, 8N1) | Use this for initial IP assignment only. | | ETH0 | Management | Assign a static IP in a secure VLAN. | | ETH1, ETH2 | Bonded data ports | Must be configured AFTER ETH0 is live. | | USB | Not used | Leave empty (prevents boot-order conflicts). | Common mistake: Forgetting to set the same MTU
Warning from field reports: Connecting a network cable to ETH2 before ETH1 is configured will cause a spanning-tree loop if your switch has PortFast disabled. The manual clarifies this in Appendix D.
If your query’s “hot” refers to ambient temperature, follow these guidelines:
| Temperature Range | Action Required |
|------------------|------------------|
| 25–30°C (77–86°F) | Standard operation, ensure front-to-back airflow unobstructed. |
| 30–35°C (86–95°F) | Reduce adjacent equipment density. Check fan speed via CLI: show system environment |
| >35°C (>95°F) | Do not install – The 3B will throttle performance and may shut down. | Date: April 12, 2026 Target Audience: Enterprise Security
The 3B uses dual redundant fans. In a hot aisle containment setup, position the unit in the cold aisle (front intake).
