Chapter 3 Installing the TimeProvider

This procedure is common for all cards.  

To insert a card into the shelf:

1. Align the card edges within the guides of the selected slot.

2. Slide the card into the chassis and press firmly until it seats fully into its 

backplane edge connector.

3. Tighten the captive screws located on each side of the panel.

To remove an IOC, lift the tabs on the front panel and slide it out of the shelf. Be 
sure to place the card on a static-free surface.

To remove the IMC or IMC/TPIU, loosen the captive screws and pull on the 
U-shaped handle.

To remove the Input, or Output modules, loosen and then pull out on the captive 
screws.

Note: Cards can be removed and inserted while system power is supplied 
without damaging modules; however, system performance may be affected.

Caution: For continued EMC compliance, replace all deformed module 
gaskets with the same type. Clean gaskets and mating surfaces. Secure all 
cards with captive screws.

Caution: To avoid possible damage or intermittent failures, ensure that you 
have completely inserted the card into the chassis and that you have 
securely tightened the captive screws.
