I recently have been using a Juniper EX2200 switch, which is quite nice, 48port, POE and much cheaper than a Cisco equivalent like a 2960S. When you initially turn on the switch you will see some alarm lights which is a Red LED and a Amber LED. The Red LED basically means the management port at back of the switch isnt in use, and the Amber means the configuration isnt saved as part of the rescue if anything goes wrong. To switch off these lights simply perform these commands:
RED LED – set chassis alarm management-ethernet link-down ignore
AMBER LED – request system configuration rescue save
