- Installation guide
Overview
The AT-PWR11 is an DC redundant power supply for the AT-8400 Series switch.
When installed, the unit operates in a standby mode. If the standard power supply
fails or loses power, the AT-PWR11 unit changes from standby to active and
provides all power to the system to prevent a network failure.
Note
The power supply is hot-swappable. You can install it without powering off
the chassis.

Installing the AT-PWR11 Power Supply
Before installing a power supply, please note the following:
❑ Refer to the AT-8400 Series Switch Reference Guide for electrical safety and
emission information.
❑ The AT-PWR11 unit must be installed in a DC powered AT-8400 Chassis.
This type of chassis has two DC terminal blocks on the back panel.
❑ There may be several different models of DC power supplies. Each model
is rated for a different power load. Both power supplies in an AT-8400
chassis must be of the same model type. Do not mix power supplies with
different power ratings in the same chassis.
To install the AT-PWR11, follow these steps:
1. Using a Phillips screwdriver, loosen the two captive screws that secure the
power supply cover to the chassis and remove the cover from the chassis. The
cover is removed by angling it from the bottom as you slide it down and out of
the chassis.
2. Using a Phillips screwdriver, loosen the captive screw that secures the cover
over the power supply PWR B slot and slide the cover from the chassis.
Note
Store the cover in a safe place. You should reinstall it if you ever remove a
power supply from the chassis without installing a new one.
3. Place the locking levers on the new AT-PWR11 unit in the released position.

4. Slide the new AT-PWR11 power supply into the power supply slot until it makes
contact with the backplane of the chassis. Be sure that the labeling on the
power supply is right-side up. Also be sure to align the green board on the
power supply with the slots in the chassis. Once the power supply makes
contact with its connector on the backplane, press firmly to fully seat the power
supply on the power connector.
Note
If you are unable to slide the power supply completely into the slot, you may
have purchased the wrong type of power supply for the chassis. A DC
powered chassis will have two DC terminal blocks on the back panel.
5. Move the locking levers on the AT-PWR11 unit into the locked position and
tighten the captive screw to secure the power supply in the chassis.
Note
Always use the installation screw to secure the power supply to the switch.
Leaving the power supply partially seated may cause the system to halt and
subsequently crash.
6. Slide the power supply cover back into the chassis and secure the cover by
tightening the two captive screws.

Wiring the AT-PWR11 Power Supply
Warning
ALWAYS connect the wiring to the LAN equipment first before connecting
the wiring to the breaker. To avoid the danger of physical injury from
electrical shock, do not work with HOT feeds. Always be sure that the breaker
is in the OFF position before connecting the wiring to the breaker.
Note
A tray cable is required to connect the power source if the unit is powered by
centralized DC power. The tray cable must be UL listed Type TC tray cable and
rated at 600 V and 90 degree C, with three conductors, minimum 14 AWG.
1. On the rear side of the chassis is a DC terminal block labeled POWER B. Starting
from the left side of the terminal block, identify the positive, frame ground
and negative terminals using the symbols beneath to the terminal block.
2. With a 14-gauge wire-stripping tool, strip the three wires in the tray cable
coming from the DC input power source to 8mm
± 1mm (0.31 in., ± 0.039 in.).
Warning
Do not strip more than the recommended amount of wire. Stripping more
than the recommended amount can create a safety hazard by leaving
exposed wire on the terminal block after installation.
3. Connect the frame ground wire to the terminal marked with the ground
symbol by inserting the wire into the terminal and tightening the connection
with a flathead screwdriver.
Warning
When installing this equipment, always ensure that the frame ground
connection is installed first and disconnected last.
4. Connect the -48 VDC RTN feed wire to the terminal block marked + (plus).
5. Connect the -48 VDC feed wire to the terminal block marked - (minus).
8mm ±1mm
(0.31in. ±0.039 in.)
40-60VDC
Warning
"Safety Hazard"- Check to see if there are any exposed copper strands
coming from the installed wires. When this installation is done correctly
there should be no exposed copper wire strands extending from the
terminal block. Any exposed wiring can conduct harmful levels of electricity
to persons touching the wires.
6. Secure the tray supply cable near the rack framework using multiple cable ties
to minimize the chance of the connections being disturbed by casual contact
with the wiring. Use at least four cable ties, separated four inches apart. Locate
the first one within six inches of the terminal block.
Note
This system will work with a positive grounded or negative grounded DC
system.
7. Ensure that the circuit breaker is in the OFF position.
8. Connect the supply-cable wires to the circuit breaker.
9. Energize the circuit breaker.
