Cable routing recommendations
Interface cables and power cords should be separately routed. Reasonable cable routing can improve
efficiency by facilitating installation and removal of fan trays, PEM, and some other components. Follow
these guidelines when you route the cables:
Interface cables of a 12508 and 12518 are routed through the upper and lower cable management
•
brackets on the chassis and bound at cabling racks on chassis sides, depending on the available
equipment room condition.
Put all the data signal cable adapters neatly under the chassis (instead of any places outside the
•
chassis in case of unexpected damages).
The power cords run along the left-rear of the chassis and out of the chassis either from the chassis
•
top or the raised floor depending on the equipment room conditions (power distribution rack,
lightning protection box, and connector strip, etc.) of the exchange office.
•
Fix cables as near the switch as possible. The cables between the fixing point and switch interfaces
must be bound loosely.
Long cables can be bound with cable ties. Do not bind cables at the air exhaust vent to prevent the
•
cables from aging too fast. For more information, see "Appendix E Cable management."
•
To identify cables, you can stick labels on them. For more information, see "Appendix F
Engineering labels for cables."
Logging in to the switch
Logging in through the console port is the most common way to log in to a switch. It is also the
prerequisite to configuring other login methods.
Connecting the console cable
Before logging in to the switch through the console port, use a console cable to connect the serial port
of your PC (or terminal) to the console port of your switch.
Introduction
A console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for connecting
to the console port of the switch, and a DB-9 female connector at the other end for connecting to the
serial port on the console terminal.
