Serial COM Port
The 2824 (managing) hub contains a serial COM port that uses a DB9
connector with a standard AT pinout. This port lets you perform the following
operations:
■
XMODEM firmware downloads
■
VT100 console interface for basic management and initially setting the
IP address
■
SLIP (Serial Line Internet Protocol) transfers, including remote (out-of-
band) management, SNMP, Telnet, and TFTP firmware downloads.
