4: Port Numbering and Cabling

DC 900-1331F 71

4.2.1 Freeway 4000 Rules for Port Numbering

If your Freeway does not match any of the example conﬁgurations in the previous ﬁg-

ures, use the following rules to determine the port numbering scheme:

• ICPs are numbered as shown in Figure 4–12 on page 72. ICP 0 is normally the

bottom ICP directly above the CPU board. If there are fewer than four ICPs, the

empty slots are at the top.

• WAN connector panels are numbered as shown in Figure 4–13 on page 72. If

there are fewer than four panels, the empty cutouts are in the highest-numbered

positions.

• The lowest-numbered ICP is connected to the lowest-numbered WAN connector

panel. The next highest ICP is connected to the next highest WAN connector

panel, and so on, unless you have two 8-port ICPs and a 16-port panel. In that

case, the both ICPs are connected to the same WAN connector panel.

• The 8-port and 16-port WAN connector panels are numbered as shown in

Figure 4–2 and Figure 4–3 on page 61 unless you have a 16-port ICP with two

8-port WAN connector panels. In that case, the connector panels are numbered as

shown in Figure 4–6 on page 64 for a Freeway 2000 or Figure 4–10 on page 69 for

a Freeway 4000.

After you have familiarized yourself with these rules, use the worksheet in Figure 4–14

on page 73 to record your port numbers for future reference. To ﬁll in the sheet, ﬁrst

enter 8 or 16 as the number of ports for each board. Then draw in and number 8 or 16

ports in each WAN connector panel similar to the way they appear in the examples in

Figure 4–8 through Figure 4–11. Next, based on the above rules and your study of the

examples, draw lines showing the connections between the ICPs and the WAN connec-

tor panels. Finally, ﬁll in the “Connected to ICP” number for each WAN connector

panel. Also ﬁll in the electrical interface as shown in Figure 4–1 on page 60.
