Power Supply Options

For PSU specifications and maximum current loads, see “AT-SB4161 & 2 
SwitchBlade Power Supply Units” on page 19. The number of PSUs 
required depends on the particular configuration selected, i.e. the number 
of line cards, controller cards installed. Consult your authorised Allied 
Telesis distributor or reseller for more information.

Note: Because certain chassis models contain additional circuitry to control power 
supply switching, the voltage ranges specified for the chassis can differ from those 
separately specified for the power supply.

AC models

Universal (110 to 240) V AC, (50 to 60) Hz input

DC models

48 V DC, (40 to 60) V DC operating range

Accepts positive or negative earthing (grounding)

LEDs

System status LEDs on each switch controller

Port LEDs on each line card

Power supply status LEDs on each PSU and switch controller

For a complete list of LEDs and their functions, see “LEDs and What 
They Mean” on page 47

Configuration and Management Ports (AT-SB4211 switch controller)

Standard DB9 female RS-232 connector for configuration and low-level 
management (on switch controller)

10/100TX RJ-45 port for switch management (on switch controller)

See “AT-SB4211 and AT-SB4211 V2, Switch Controller” on page 22 for more 
information on management ports
