Deployment and Installation Guidelines

To ensure the ISR 4321 achieves its intended lifespan in the varied Pakistani climate, the SKYRS technical team adheres to the following standards:

Physical Installation:

• Space & Airflow: While the 4321 is compact and fanless (making it ideal for quiet office environments), it requires at least 2 inches of clearance on the top and sides for passive cooling in high-ambient regions like Sindh or Punjab.

• Rack Mounting: SKYRS provides the original 19-inch rack-mount kit. Ensure the router is placed away from heat-generating equipment (like older UPS systems).

• Cabling: Use only high-quality Cat6 cables for Gigabit WAN uplinks. For SFP connections, SKYRS provides Cisco-certified GLC-LH-SMD or GLC-SX-MMD transceivers.

Power and Safety:

• External Power Brick: The ISR 4321 uses an external power adapter. SKYRS recommends securing this adapter with a cable tie to the rack to prevent accidental disconnection.

• Surge Protection: Due to power instability, it is mandatory to connect the unit to a regulated Online UPS.
