Installing A Power Supply Unit (PSU)
All AC and DC versions of this equipment must be earthed.
PSUs can be hot swapped. When swapping PSUs, the SwitchBlade 8 (AT-SB4108) will
continue to operate as long as two functional PSUs remain in place. The SwitchBlade 4
will continue to operate as long as one functional PSU remains in place.
Follow these steps to install a PSU:
1. Read the safety information
The SwitchBlade Safety and Statutory Information booklet includes all
relevant safety information. A copy of the safety booklet is supplied with
each PSU. It can also be found on the CD-ROM that ships with every
switch controller and every chassis, or can be downloaded from
www.alliedtelesyn.co.nz/support/switchblade/.
2. Gather the tools and equipment you will need
To loosen or secure the PSU’s mounting screws you will need a Phillips #2
screwdriver.
3. Choose a PSU bay
PSU bays should be filled from left to right.
Unless replacing an existing PSU, choose the empty PSU bay that is nearest
to the chassis’s front left-hand corner.
4. Prepare the PSU
In an antistatic environment, remove the PSU from its packing material. Be
sure to observe ESD precautions.
Do not attempt to install a PSU without observing correct antistatic
procedures. Failure to do so may damage the chassis or PSU. If you are unsure
what the correct procedures are, contact your authorised Allied Telesyn
distributor or reseller.
An ESD socket is provided on the front panel of the SwitchBlade chassis. The socket is
designed to be used in conjunction with an ESD wrist strap (see Figure 1 on page -4).

5. Remove the PSU bay faceplate or existing PSU
To remove a blank faceplate:
Loosen the faceplate’s four Phillips mounting screws until they disengage
from the chassis, then remove the faceplate.
Keep the faceplate for future use. If you remove a PSU, replace the faceplate to prevent
dust and debris from entering the chassis and to maintain proper airflow.
The switch and PSU may overheat or be damaged by dust and debris if PSU
bays are left uncovered.
To remove an existing PSU:
Loosen the PSU’s four Phillips screws until they disengage from the chassis.
Using the PSU’s handle, pull the PSU out of the chassis.
6. Insert the PSU
Slowly and carefully slide the PSU into the chassis (see Figure 2 on
page -5).
Firmly press the PSU home (until its front panel engages or nearly engages
the chassis).
Keep the PSU in a straight alignment and insert it slowly. Forcing a misaligned
PSU is likely to damage the chassis and PSU.
Figure 2: PSU insertion.
7. Secure the PSU
Tighten the PSU’s four Phillips screws.
8. Apply AC power to the PSU (for AC models)
Plug the power cord into the PSU’s AC power connector on the chassis’s
rear panel (see Figure 3 on page -6). The connector for each PSU is the
connector that is directly behind the corresponding PSU bay.

Also plug the power cord into an outlet that can supply a voltage of 90-
264V AC.
Make sure the Standby switch is in the Run position.
Figure 3: AC power connectors.
9. Apply DC power to the chassis (for DC models)
Read the Safety and Statutory Information booklet before connecting a DC
power supply. A copy of the safety booklet is included with each PSU. A
PDF version is included on the Documentation and Tools CD-ROM
shipped with every switch controller and every chassis, or can be
downloaded from www.alliedtelesyn.co.nz/support/switchblade/.
Only trained and qualified personnel should connect a DC power supply. Due
to exposed terminals, DC powered switches should only be installed in
Restricted Access Areas.
DC supply cable specifications:
• Number of wires (cores): 3 (only 2 wires are required if the switch is
ground bonded via the separate ground terminal on the chassis’s rear
panel)
• Minimum size: 3.3 mm2(12 AWG)
•Minimumcablerating:600V, 90 degrees Celsius
DC power supply specifications:
• 48 V DC (36-59 V DC is acceptable)
• Either positive grounded or negative grounded
Circuit protection:
• Use a 20 Amp circuit breaker
To connect the DC supply:
Ensure that the supply cable is not live.
a) Strip the supply cable wires to expose 8mm (0.31 in.) of bare conductor
b) If using 3 wires, on the chassis’s rear panel, connect the ground wire to
the ground terminal for the corresponding PSU (The terminals can be

identified by the diagram on the switch’s rear panel, see Figure 4 on
page -7). Tighten the terminal to between 0.6 and 0.8 Nm (0.041 to 0.055
pound-force per foot)
If using separate ground bonding, connect a separate ground wire to
the ground bonding terminal on the chassis’s rear panel
c) On the chassis’s rear panel, connect the positive feed to the + (positive)
terminal and the negative feed to the - (negative) terminal for the
corresponding PSU. Tighten the terminals to between 0.6 and 0.8 Nm
(0.041 to 0.055 pound-force per foot)
Check that the PSU terminals are wired to the correct polarity. The PSUs will
be damaged if incorrectly connected.
d) Ensure that there are no exposed conductor strands
e) Secure the supply cable (to the rack framework or similar object) so that
the connections are isolated from any forces applied to the cable
f) Ensure that the circuit breaker is in the Off position
g) Connect the supply-cable wires to the circuit breaker
h) Energise the circuit breaker
i) Make sure the Standby switch (on the chassis’s rear panel) is in the Run
position.

10. Check the PSU’s LEDs.
If installed, the switch controller(s) have an LED labelled Power, which lights
green to indicate that at least one PSU is operational.
More troubleshooting information can be found in the SwitchBlade Hardware
Reference.

How Many PSUs Do You Need?
The number of PSUs required depends on how many bays are in use.
If any five bays are in use (one switch controller bay and four line card bays, or
two switch controller bays and three line card bays), one PSU is sufficient.
Installing a second PSU provides N+1 redundancy.
If six or more bays are in use (one switch controller bay and five line card bays,
or two switch controller bays and four line card bays), two PSUs are required.
In this case, installing a third PSU in the SwitchBlade CH8 chassis provides
N+1 redundancy.
