Applying Power to the Switch
Power supply bays are in the rear of the switch. Depending on the model, the
switch may have a PSU, FOM, or blanking plate over a power supply bay.
Connecting an AC power supply
Follow these instructions to connect one of the following to an AC power supply:
■
an AT-PWR01, AT-PWR02, or AT-PWR05 AC PSU
■
an x900-12XT/S switch
Warning The AT-PWR01 AC PSU has a fuse rating of 250V, 5A for FH101 and
FH102.
Warning The AT-PWR01 AC PSU has double pole/neutral fusing. Electric
shock is possible since there are dual primary fuses, one on the phase circuit and
one on the neutral circuit. If the neutral opens, the phase may still be live.
Warning For SwitchBlade x908 AC models the grounding stud on the rear of
the unit is for supplemental grounding only. The system must be supplied by a
grounded 3 wire AC source through the power supply cord.
1.
Plug the AC power cord that is provided into the power inlet on the PSU.
2.
Connect the power cord to the main power source.
3.
On the AT-PWR05, set the Run/Standby switch to Run.
4.
Check that the PSU LED on the front panel of the switch is lit green. If the
LED does not light, refer to the Hardware Reference for troubleshooting
information.
Connecting a DC power supply
Follow these instructions to connect an AT-PWR01-80 DC PSU to a DC power
supply. Only trained and qualified personnel should connect a DC power supply.
For centralised DC power connection, the switch should be installed in
restricted access areas only, such as dedicated equipment rooms or
equipment closets, in accordance with Articles 110-16, 110-17, and 110-18 of
the National Electrical Code, ANSI/NFPA 70.
