Installing Nodes in Modulus Enclosures

To install a node with a TRIM card in the left-most position of a nest, attach the backplane at Slot 3 of the nest. Insert the TRIM/processor card into Slot 3. The TRIM card takes up Slot 2 and Slot 1 (the width of the card does not permit it to be installed in Slot 1). The TRIM card rear filler panel, which has cutouts for the LAN port connectors, covers the backplane in Slot 2; a stan- dard Modulus 9/21 rear filler panel covers the back of Slot 1. Two standard Modulus 9/21 front filler panels cover Slots 1 and 2 at the front of the nest.

If there is a product in the nest, such as a modem, that consists of a one-slot wide product card plugged into a two slot-wide backplane, then one slot can be saved when installing a TRIM. The modem product should be installed to the left of the TRIM card.

To install a node with a TRIM card next to another product backplane, leave one slot empty between backplanes. Modulus 9/21 product backplanes take one slot in addition to what their product cards take. For example, a 54- port backplane takes up 19 slots, although its nine cards take up 18 slots (two slots per card). The TRIM backplane fills the one slot between the two backplanes. The TRIM card itself fills the one slot gap and one slot from the adjacent backplane. Two standard Modulus 9/21 front filler panels cover the front of the TRIM card’s slots in Modulus 9/21 enclosures (Figure 2-12). This works only if a one-slot card is installed to the left of the node.
