•
To prevent serious eye damage, never look directly into a fiber optic cable
connector or mating adapter.
•
Clean all fiber optics before installing them into your network according to
prescribed procedures.
•
Ensure that the bend radius of your fiber cables is kept to a minimum of 3" or that
specified by the fiber cable manufacturer.
•
Perform all cabling procedures according to the established standards for your
organization.
To connect network optical cabling to the optical physical interface cards:
Locate the fiber optic cables you plan to connect to the Acme Packet 3900.
1.
Connect the optical cables to their corresponding ports.
2.
Route the cable away from the Acme Packet 3900. Make sure that the fiber optic
3.
cables are not stretched tightly or subjected to extreme stress.
Repeat Steps 1 through 3 for each additional fiber optic cable you connect to your
4.
Acme Packet 3900.
Cabling for HA Deployments
The information and instructions in this section explain how to cable an HA node.
HA Cabling
Category 5 (or higher) shielded Ethernet cables are required for cabling two HA nodes
together.
Rear Panel Cabling
You can use one or two connections for HA redundancy support between the two
members of an HA node. Using two rear interfaces for sharing redundancy information
provides a high level of reliability. As a rule, network management ports should be
used in this way:
•
Mgmt0 should be reserved as the boot/maintenance interface.
•
Mgmt1 and Mgmt2 are available for sharing HA information.
Management network ports feature automatic crossover negotiation so that a
crossover cable is not necessary for HA cabling.
Insert one end of an Ethernet cable into either Mgmt1 or Mgmt2 on the rear panel
1.
of the Acme Packet 3900 A. The release tab on the RJ45 jack clicks into place
when you insert it properly.
Insert the other end of the Ethernet cable into the corresponding management
2.
interface on the rear panel of the Acme Packet 3900 B. The release tab on the
RJ45 jack clicks into place when you insert it properly. If you use Mgmt1 on Acme
Packet 3900 A, then you will connect it to Mgmt1 on Acme Packet 3900 B.
Refer to the configuration procedures located in the High Availability chapter of the
3.
Configuration Guide.
