Lowering the Cable Management Tray
Step 1 At the rear of the chassis, apply slight upward pressure at the base of the cable management tray.
Step 2 Flip the latches on the swing arms upward and free of the posts.
Step 3 Lower the tray until it rests against the chassis.
Step 4 If you are removing an MIO/UMIO card, refer to Detaching Network Cables from the Card Bracket, on page 165 .
Otherwise, remove the circuit card as described in the Remove and Replace the Circuit Card section of the Replaceable
Components chapter.
Step 5 Proceed to Raising the Cable Management Tray, on page 166 .
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
Step 3 Proceed to Raising the Cable Management Tray, on page 166
