Port Cabling Specifications
Console Port
The Catalyst 4500 series Supervisor Engine II-Plus TS console port has an EIA/TIA-232 RJ-45
connector. The console port allows you to perform the following functions:
• Configure the switch from the CLI
• Monitor network statistics and errors
• Configure SNMP agent parameters
Note EIA/TIA-232 was known as recommended standard RS-232 before its acceptance as a standard by the
Electronic Industries Alliance (EIA) and Telecommunications Industry Association (TIA).
RESET Button
The RESET button is used to restart the switch.
Note Use a paper clip or other small, pointed object to press the RESET button.
Flash Port
The Flash port accepts a Type 1 compact Flash card. You can use it for file transfer tasks such as loading
a new software image. The Flash card is optional and can be obtained from Cisco resellers or directly
from Cisco.

Port Cabling Specifications
This section provides port cabling specifications.
The length of your networks and the distances between connections depend on the type of signal, the
signal speed, and the transmission medium (the type of cabling used to transmit the signals). The
distance and rate limits in this document are the IEEE-recommended maximum speeds and distances for
signaling. Table 2 shows the transmission speed versus the distance.
