hardware meet requirements. For proper operation, use only approved
cables when you install all equipment.
The console and auxiliary ports on the Edge Router module require a

the specifications described in this section or you can purchase the 3Com

Router module.
■

To connect the mini-DIN to DB-25 cable to another DTE device, use a null
modem adapter.
