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
.
