The following LEDs report operations and faults on the PWR05 PSU
The following table describes LEDs on the PWR05 AC power supply unit.
The following table describes LEDs on the PWR05 DC power supply units.
x900-12XT/S
fixed AC PSU
Key features are:
■
Universal 100–240 V AC 50/60 Hz input
■
Maximum continuous current draw: 2 A at 90 V, 0.8 A at 230 V at full-rated
load
■
Maximum inrush surge current (cold start at 25º C/77º F): 33 A peak at
115 VAC
A single LED on the front panel of the switch reports operations and faults on
the PSU. See
“System LEDs” on page 17
for more information.
IPv6 Accelerator Card
An optional AT-ACC01 network processor accelerator card accelerates IPv6
unicast and multicast routing in hardware on AT-8948 switches. For full
functionality, 512 MBytes SDRAM must be installed in the switch.
How the card works
When the switch receives an IPv6 packet to route, the packet is sent to the
network processor accelerator card. The card processes the packet and sends it
out the correct port with appropriate alterations to the packet. Other IPv6
functions are passed to software, such as routing protocol control packets,
encryption, authentication, and hop-by-hop headers.
LED
State
Description
~
IN
Green
AC input voltage is within 90-264 VAC, 47-63Hz.
Off
AC input voltage is outside the acceptable range.
OUT
Green
DC output voltage is within 12V +/- 10%.
Off
DC output voltage is outside the acceptable range, or the Standby
switch is Off. If a fault occurs then the FAULT LED will display and
the OUT LED will be Off.
FAULT
Red
A fault has occurred. There is either a fan failure, or the
temperature has exceeded its limit of 70º C (158º F).
Off
No fault conditions detected.

Off
DC input voltage is outside the acceptable range.
OUT
Green
DC output voltage is within 12V +/- 10%.
Off
DC output voltage is outside the acceptable range, or the Standby
switch is Off. If a fault occurs then the FAULT LED will display and
the OUT LED will be Off.
FAULT
Red
A fault has occurred. There is either a fan failure, or the
temperature has exceeded its limit of 70º C (158º F).
Off
No fault conditions detected.
