Connecting an AC power supply
Follow these instructions to connect an AT-PWR01, AT-PWR02, or AT-PWR05
AC PSU to an AC power supply:
Warning The AT-PWR01 AC PSU has a fuse rating of 250VAC, 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 When x900-24 units are connected with VCS stacking cables (XEM-
STK-CBL) ensure that all the PSUs are appropriately grounded. This is to avoid
large circulating ground currents that could damage the stacking cables. To
achieve this ensure that:
■AT-PWR01 AC is grounded by the 3-pin AC power connector
■All grounding points are at the same ground level. That is, all power
connectors share a common power distribution unit.
Warning For SwitchBlade x908 units with AC PSUs, the grounding stud on the
rear of the device is provided for situations where an additional ground is
required. The device must be powered from a grounded 3 wire AC source via the
AC power cable and connector.
Warning When SwitchBlade x908 units are connected with VCS stacking
cables (either HS-STK-CBL or XEM-STK-CBL), each individual stack member
chassis must be additionally grounded by using the rear grounding-terminal on
each device. In order to avoid large circulating ground currents, thewires of each
grounding cable must be 18 AWG (0.8mm2) or thicker.

Connecting a PWR01 or PWR02
1. Plug the supplied AC power cable into the power inlet on the PSU and
attach the retaining clip.
2. Connect the power cable to the main power source.
3. The PSU LED on the front panel of the switch lights green. If the LED does
not light, refer to the Hardware Reference for troubleshooting information.
Connecting a PWR05 (AC version only)
The rear grounding-terminal is not necessary for the SwitchBlade x908 when
using AC PSUs because the chassis is grounded through the power cable.
1. Form a loop in the supplied AC power cable at the PSU end and clip the
ferrite core over the looped cable, as shown in the following illustration.
This keeps the ferrite core in its correct position, close to the PSU.

2. Plug the AC power cable into the power inlet on the PSU.
3. Connect the power cable to the main power source.
4. Check that the Run/Standby switch is set to the Run position (1). Both the
AC IN and DC OUT LEDs should be lit.
Note that when the Run/Standby switch is set to the Standby position (O),
the AC IN LED lights and the fan spins, but the DC OUT LED does not
light and the PSU does not deliver power to the device.
5. The PSU LED on the front panel of the switch lights green. If the LED does
not light green, check the Run/Standby switch. See the Hardware Reference
for more troubleshooting information.

Connecting a PWR01 DC power supply
Follow these instructions to connect an AT-PWR01 DC PSU to a DC power
supply. Only trained and qualified personnel should connect a DC power supply.
You need an appropriate DC power source, DC supply cable, ring connectors, a
crimp tool and an appropriate screwdriver to tighten the terminal screws.
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.
Power supply specifications:
■functional range 40 to 60V, 48V nominal
■supports either positive grounded or negative grounded operation
■a 15Amp certified/listed circuit breaker is required for circuit protection
Supply cable specifications:
■tray cable should be UL listed Type TC tray cable (or equivalent)
■three-core cable is required
■minimum core size: 3.3mm2(12 AWG) high strand count copper wire
■minimum cable rating: 600V, 90 degrees C
Warning Disconnect the power supply cable before starting this procedure.
1. Remove the transparent protective terminal cover.
2. Strip the supply cable wires to expose 7.5mm (0.31 in.) of bare conductor.
Terminate the wire with a nylon insulated solderless ring tongue terminal,
JST FN5.5-5 or equivalent, using a crimp tool.
3. Connect the ground wire to the ground terminal. Use the diagram on the
rear panel of the switch to identify terminals. Tighten the terminal to
between 2.4 and 4.0 Nm (21.3 and 35.4 lbf in).
Warning When x900-24 units are connected with VCS stacking cables (XEM-
STK-CBL) ensure that all the PSUs are appropriately grounded. This is to avoid
large circulating ground currents that could damage the stacking cables. To
achieve this ensure that:
• AT-PWR01 DC is grounded at the GND terminal. In order to avoid
large circulating ground currents, the wires of each grounding cable
must be 18 AWG (0.8mm2) or thicker.

• All grounding points are at the same ground level. That is, all power
connectors share a common power distribution unit.
Warning Whenmountingoneortwo AT-PWR01DC PSUstoa groundedrack,
ensure that the ground level of the rack and the DC power connector are the
same.
4. Connect the positive feed to the + (positive) terminal and the negative feed
to the - (negative) terminal. Tighten the terminals to between 2.4 and
4.0Nm (21.3 and 35.4 lbf in).
Note that the DC return input terminal must be connected as an Isolated
DC return (DC-I).
Warning In orderto avoid damaging the PSU, make sure that thePSU terminals
are wired to the correct polarity.
5. Ensure that there are no exposed cable strands.
6. Replace the cover. You must replace the transparent plastic terminal cover
before continuing.
7. Secure the supply cable to the rack framework or a similar object to ensure
that connections are isolated from any force applied to the cable.
8. Ensure that the circuit breaker for the supply circuit and the Run/Standby
switch on the PSU are off. Press and release the Run/Standby switch so that
it is not pushed in (which is the Off position).
9. Connect the supply cable wires to the circuit breaker.
10. Turn on the PSU by pushing in the Run/Standby switch.
