The procedure for hot swapping a card in the rear of a VM600 rack is as follows.
First, in the front of the rack:
1- Remove any associated processing card in the corresponding slot in the front of the rack
from the rack’s backplane (see 3.1.4.1 Hot swapping a card in the front of a VM600 rack).

4- Insert the replacement card in the rear of the rack.
5- Reconnect all of the cables to the card.
Finally, in the front of the rack:
6- Reinsert the associated processing card in the corresponding slot in the front of the rack
(to the rack’s backplane).
3.1.4.3 Removing cards safely
The AMC8, MPC4, IOC4T, IOC8T, RLC16 and IRC4 cards all feature a lever mechanism to
help the user to easily remove the card. Follow the procedure below and see Figure 3-1):
1- Disconnect all external cables connected to the card, for example, the communication
cable (RS-232) for an MPC4 card or front-end cables (J1, J2 and J3) for an IOC4T card.
2- Unfasten the two captive fixing screws. These are found at the top and at the bottom of
the front panel.
3- With your thumbs, simultaneously push the upper handle upwards and the lower
handle downwards. These combined actions will cause the card to move forwards by
1to2mm.
4- Pull on both handles together (with equal force) to extract the card from the rack.
NOTE: Remember to reconnect all of the cables after a card is replaced in the rack.
Before ‘hot swapping’ a card in the rear of a VM600 rack, any associated
processing card in the corresponding slots in the front of the rack must be
disconnected from the rack’s backplane.
