Switch Hardware and Functionality

Each power supply can provide the following:
– Hot-swappable/hot-pluggable, redundant power
– Load sharing between two power modules
– Separate AC line power cord for each power module
– Power Module Input: 100-240 VAC; 47-63Hz, 4 -2A
– Active Power Factor Correction (PFC)
If the power unit is operating properly, then the individual LEDs and
external warning LEDs are lit green. If you remove a power supply, then
the warning buzzer in the power system sounds, and the external warning
LED, which displays the status of the total power supply system, begins
to blink. The LEDs on the front of the power module, which indicate the
power supply’s status will not light. The power supply continues to back
up the power output without affecting the computer system’s operation.
When the warning buzzer sounds, you can reset it by pressing the buzzer
reset or by using the reset switch on the system chassis. When you
re-insert the power module removed earlier, the sound of the warning
buzzer disappears and the external warning LED turns green again.
• ARX-4000 Power Supply
To provide full redundancy and load-sharing, the ARX-4000 is powered
by four fully-managed AC/DC power supplies.
The AC/DC power supplies provide the following functions:
– 400 Watts @ +2.5 V, +3.3 V, and +12.0 V for switch operations. The
power supply draws a total of 440W from the AC power cord due to
its operating efficiency.
– Remote sensing to maintain stable voltage and to account for any DC
loss in cabling.
The power supplies in the control plane and data plane differ in
appearance and in LEDs. The power supplies in the control plane have
one LED. The following table lists and describes the states indicated by
this LED.
The power supplies in the data plane have three LEDs. The following
table lists and describes the states indicated by these LEDs.
Table 4.27
ARX-4000 Control Plane Power Supply LED States
LED
State
Solid green
AC power present.
Amber
Fault detected (for example: power removed, fan faulted).
However, the LED is able to light amber only if the redundant
control plane power supply still has power. If power has been
removed from both power supplies, the LED will be off.
Off
AC power absent.
