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.
