Connecting the Cables
This chapter describes how to connect the interface cables, power the system, and check the status LEDs
on circuit cards to make sure you have installed everything properly.
Cisco MGX 8260 configurations will require some type of cable management plan for the WAN cabling.
This may include the installation of vertical and horizontal cable raceways that bolt to the racks.
The MGX 8260 uses the following cable types:
•
BITS—STP (Shielded Twisted Pair) cables for the timing source, terminated with RJ-45 connectors
•
DS3—Coaxial cables for DS3 lines terminated with SMB connectors (see
Table 5-1
)
•
T1—STP cables for 100-ohm T1 lines terminated with 50-pin RJ-21 connectors
•
E1—STP cables for 120-ohm E1 lines terminated with RJ-48 connectors
•
Fast Ethernet—Category 5 STP cables for 100BASE-TX lines terminated with RJ-45 connectors
•
OC-3—Single or mulitmode fiber cables for OC-3 lines terminated in small form factor LC or
MT-RJ connectors
•
10BASE-T—Category 5 STP cables for Ethernet management ports terminated with RJ-45
connectors
•
Alarm—Custom cable for visual or audible alarm indications terminated on a DB-15 connector
•
Console—EIA/TIA-232 serial cable for a console terminated with a DB-9 connector
•
Aux—EIA/TIA-232 serial cable for a modem terminated with a DB-9 connector
•
DC Power—12 AWG ST, UL 1015 wires for power and return. 8 AWG for safety ground
