Detaching Network Cables from the Card Bracket
Step 1
Cut the nylon cable ties or open the hook-and-loop straps that secure network cables to the MIO/UMIO card.
Step 2
Unplug the cable connectors starting from the top ports.
The ends of all network cables should be labeled with their slot/port terminations. If this has not been done,
you should label each cable as you disconnect it.
Important
Step 3
Move the cable bundles away from the MIO/UMIO. You may have to re-open the hook-and-loop straps in the cable
management tray to free the cables.
Step 4
Remove the MIO/UMIO card as described in Remove and Replace the Circuit Card section of the Replaceable Components
chapter.
Never use the cable management bracket as a "handle" to remove or lift an MIO/UMIO. The bracket is not
designed to support the weight of an MIO/UMIO.
Caution
Reconnecting Network Cables to the Card Bracket
Step 1
The replacement MIO/UMIO card should have a cable management bracket pre-installed as described in Installing Cable
Management Brackets, on page 160
Step 2
Route the cables and secure them to the bracket as described in Routing and Securing Network Cables, on page 162
