5 Reboot the router to initialize the newly installed option card.
If you installed an E4G-B16T1E1 module, follow the instructions in
Connecting a Cable for the E4G-
B16T1E1 Module
on page 61.
Save the slot cover to re-use in case you remove the port option card later. An unoccupied module slot
must be covered to ensure satisfactory EMI levels and to maintain adequate airflow through the router.
Connecting a Timing Cable to the E4G-400 Router
The front panel of the E4G-400 router provides the following types of cable connections for connecting
a Building Integrated Timing Supply (BITS) or a GPS timing source:
•
Two mini-BNC connectors labeled IN
•
1 PPS input
•
10 MHz input
•
Two mini-BNC connectors labeled OUT
•
1 PPS or 8 KHz frame output
•
10 MHz or 2.048 MHz or 1.544 MHz output
To connect to the mini-BNC connectors, use a 50-ohm coaxial cable with a mini-BNC connector at
one end and a standard BNC connector at the other end.
•
One RJ-45 connector for time-of-day (ToD) input/output or for RJ422 BITS input
To connect to the RJ-45 connector, use a twisted-pair cable with the pinouts listed in
Table 77:
E4G-200 Clock Module RJ-45 Connector
on page 106.
Connecting a Cable for the E4G-B16T1E1 Module
The ports on the E4G-B16T1E1 module are implemented as MRJ21 connectors.
Each connector represents eight ports. Two cable types are available for these ports:
•
MRJ21-to-RJ-45 fan-out cable (Extreme Networks part number 16220; see
the figure below
)
