36 Chapter 2 Contivity 4500 Option Installation
302283-E Rev 00
Installing Contivity 4500 LAN/WAN and hardware
accelerator option cards
This section describes how you install option cards into the Contivity 4500 option
card slide-out tray. The following procedure is for Nortel Networks trained service
personnel only.
1
Turn off the switch and unplug both power cords from the power source.
2
Unscrew the four slotted thumb screws securing the slide-out tray. Pull out the
tray by gripping it with the screws. It will only pull out half way.
3
Remove the filler panel screw and pull out the slot filler panel.
4
Slide the option card into the intended slot. Make sure the card seats firmly
and evenly into the card slot. If the card is not seated properly, it will not
work. Populate the slots from Slot 1 to Slot 6, in that order.
5
Secure the option card in the tray with the slot filler panel screw.
6
Push in the tray by gripping it with the screws. Tighten the four slotted thumb
screws securing the slide-out tray.
7
Plug in both power cords to the power source and turn on the switch.
Caution:
Be careful when inserting option cards into the Contivity
4500, because the slide-out tray is not fully supported once pulled out.
You should support the back of the tray with your hand while inserting
an option card.
