4550T Configuration for closet use

For closet use, there is no need to create separate VLANS as telephones hook up to the TLAN.

Check the current firmware version with show sys-info, and perform a Firmware Upgrade if required.
Factory Reset the switch: enter restore factory-default, and confirm. The switch will re-boot.
If a password is required but not known, see: Reset to Factory Defaults.

Setup:

Now we can continue using the web interface... (use Port 1 as the management port)

VLANS ➤ SETTINGS ➤ AUTO PVID (make sure autopvid is set)
 BASIC ➤ Remove all ports except 1, 49 and 50
Insert VLAN ID 2
Select ALL Ports except 1
MLT/LACP ➤ VLAN ➤ ENABLE TAGGING - TAG ALL (Trunk)
Multiline trunks #1 Ports 49 and 50

Note: The web interface is compatible with Internet Explorer versions 8.x and 9.x, or Mozilla Firefox 23.x
To access the web interface from a Mac, use an old version of firefox, such as Firefox 3.6.28 download

Configuration Backup

From the TTY, issue the following commands (with a TFTP server running on 10.10.10.1):

save config
copy running tftp address 10.10.10.1 filename ers.cfg

Alternatively, backup to a USB thumb drive plugged into the front panel with the following command:

copy run usb filename ers.cfg

Note: Details about setting up a local TFTP server, such as SolarWinds or PumpKIN, can be found elsewhere. Running a TFTP server is highly recommended. A TFTP server on your ELAN will assist with soft/firm/load-ware updates and configuration backups.
