Installing Active Cards
2 Insert the cards into the frame by sliding them into card guides from the front of the router. Use
the levers to fully seat the card into the motherboard connectors. On all cards, the text on the
card edge should be facing outward.
Insert the card in designated slots only, as follows. (See Figure 3-4 on page 32.)
• Control cards — insert in horizontal slots, located near the bottom of the frame. Levers are
located at the right and left edges of each card.
• Input cards — insert in the vertical, lower bay slots. Levers are located at the top and bottom
of each card.
• Output cards — insert in vertical, upper bay slots. Levers are located at the top and bottom
of each card.
• Crosspoint cards — insert in the vertical, center slots: Levers are located at the top and
bottom of each card.
In the
left slot, insert a crosspoint card for inputs 1–256.
(Optional) In the middle slot, insert a crosspoint card. The card is automatically in “hot”
standby mode and acts as a backup for the crosspoint cards installed in the right or left
crosspoint card slots. For more information, see
Middle Slot Functions on page 19.
In the right slot, insert a crosspoint card for inputs 257–512. These inputs are received
through the I/O signal expansion connections. Signal Expansion Connections on page 34.
For information about crosspoint cards, crosspoint card slots and outputs managed, see
Crosspoint Cards on page 18.
• (Optional) Monitor card — insert in the vertical, upper-middle slot. Levers are located at the
top and bottom of each card.
