Chapter

Port Numbering and Cabling

This chapter describes port numbering and cabling for the WAN connectors on the

back of a Freeway 2000 or Freeway 4000.

Note

We recommend that you power off the Freeway server and modem

during cable installation and removal. This will prevent damage to

an ICP due to electrical discharge as contact is made or broken.

The WAN port numbering for your Freeway depends on the types of installed ICPs and

WAN connector panels. The ICPs in the unit are 8-port, 16-port, or a mix of the two

types. The WAN connector panels are also 8-port, 16-port, or a mix. The ﬁrst step in

determining the port numbering for your Freeway is to check which types of ICPs and

WAN connector panels are installed as follows:

• For ICPs, check the ID plate on the left ejector handle of each ICP as you are

facing the front of the Freeway unit. The number before the hyphen is the electri-

cal interface, and the number after the hyphen indicates the number of ports

supported by the ICP. For example, in Figure 4–1, all ICPs support EIA-232.

ICP 0 and ICP 1 are 8-port boards and ICP 2 is a 16-port board.

• For WAN connector panels, simply look at the back of the Freeway unit. The

8-port panels have eight connectors conﬁgured as shown in Figure 4–2. The

16-port version is shown in Figure 4–3.
