Installation and Safety Guide

Selecting a Site

You can install the switch in the following ways:

■ in a standard 19-inch rack (see “Installing the Switch” on page 6)

■ on a level surface such as a desktop or bench

When you install the switch, choose a site as follows:

■ for AT-8900 and AT-9900 switches, one that maintains an ambient

temperature from 0º C to 50º C (32º F to 122º F) for AT-9900s switches, one that maintains an ambient temperature from 0º C

to 40º C (32º F to 104º F)

■ allows adequate airflow around the switch and its vents

■ is free of dust and moisture

■ maintains humidity from 5% to 80% non-condensing

■ has a reliable and earthed (grounded) power supply, preferably dedicated and

filtered

■ does not expose cabling to sources of electrical noise such as radio

transmitters, broadband amplifiers, power lines, electric motors, and fluorescent fixtures

■ permits easy access to the switch’s power and cable connections

■ allows related network devices to be connected to the switch without

exceeding maximum cable lengths specified in the Hardware Reference

■ ensures that the switch is mounted evenly in the rack to prevent uneven

mechanical loading of the rack

AT-8900, AT-9900, AT-9900s Series Switches

Installing the Switch

The switch is heavier at the rear than at the front. Therefore, we recommend that you use the supplied 19-inch rack-mount kit to fully support the switch in a rack. Using this kit is essential if the front mounting flange on the rack is easily bent, or the switch is installed in areas subject to shocks such as earth tremors or heavy vibrations.

Before you begin

■ Read the safety information.

For your well-being and that of the equipment, read the safety information in this document. You can also download this document from the Documentation and Tools CD-ROM or from www.alliedtelesyn.com

■ Verify the package contents if you have not already done so.

See “Package Contents” on page 4. If any items are damaged or missing, contact your authorised distributor or reseller.

■ Gather necessary tools and equipment.

You need a Phillips #2 screwdriver to adjust the retaining screws on the power supply unit (PSU) or fan-only module (FOM).

To install a DC version of the PSU, you need an appropriate DC power source, DC supply cable, ring connectors, and a crimp tool.

■ Choose a suitable operating location.

Follow the guidelines described in “Selecting a Site” on page 5 to choose a suitable location.

■ Decide whether two people are needed to mount the switch into the rack

and tighten the screws (step 7).

■ If you have an optional expansion module for the AT-9900s Series switch,

install it in the switch first. Refer to the Expansion Module Installation Guide for the AT-9900s Series Switch

for details.

Warning Both AC and DC versions of this equipment must be earthed.

Installation and Safety Guide

Installing the switch using the 19-inch rack-mount kit

1. Ensure the rack has sufficient space for the switch and its cables.

2. If necessary, install cage nuts at the front and rear of the rack.

3. Unpack the switch and remove the rubber feet.

4. Screw the front brackets to the sides of the switch using the M4 screws

that are supplied (see figure below).

RMOUNT3a

5. Measure the depth of the rack to determine the correct position to attach the rear brackets to the switch.

6. Screw the right rear and left rear brackets to the sides of the switch using the M4 screws that are supplied.

7. Mount the switch into the rack from the front, and attach it to the rack using rack mounting screws.

Two people may be required to safely support the switch until the brackets are screwed to the rack.

AT-8900, AT-9900, AT-9900s Series Switches

8. Fit the adjustable bracket extensions onto the rear brackets but do not tighten the nuts (see figures below).

RMOUNT5a

Installation and Safety Guide

The adjustable bracket extensions are rotationally symmetrical when attached to the rear brackets. When viewed from the rear of the switch, the flanges on the bracket extensions are at the bottom on the right and at the top on the left. This allows adequate clearance when a power supply unit or fan-only module is removed from the switch.

9. Attach the adjustable bracket extensions to the rack using rack mounting screws.

10. Tighten the nuts that secure the adjustable bracket extensions to the rear brackets.

11. Check that all screws and nuts are fully tightened.

Applying Power to the Switch

The switch has two bays in the rear. Your switch comes with one pre-installed power supply unit (PSU). Depending on the model, the switch also has one fan-only module (FOM) or one blanking panel over a power supply bay,

AC power supply

Important information for service personnel:

■ CAUTION: double pole/neutral fusing

■ the rating of fuses FH101 and FH102 is 250 V, 5 A (AT-PWR01 only)

Procedure for AC power supply

To apply power to the PSU, plug the AC power cord that is provided into the power inlet on the faceplate of the PSU. Then connect the power cord to the main power supply.

DC supply cable and power supply

Supply cable specifications

■ three-core cable is required

■ minimum core size: 3.3 mm

■ minimum cable rating: 600 V, 90 degrees C

Power supply specifications

■ 40 to 60 V, 48 V nominal

■ supports either positive grounded or negative grounded operation

■ a 15 Amp certified/listed circuit breaker is required for circuit protection

(12 AWG) high strand count copper wire

AT-8900, AT-9900, AT-9900s Series Switches

Procedure for 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/NAPA 70.

Warning Ensure that the power supply cable is not live before starting.

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).

Caution Check that the PSU terminals are wired to the correct polarity. A PSU will be damaged if incorrectly connected.

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

4.0 Nm (21.3 and 35.4 lbf in).

5. Ensure 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 the circuit breaker for the supply circuit and the Run/Standby control on the PSU are off. Use a small diameter pin to press and release the Run/Standby control 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 control with a small

diameter pin.

11. Confirm that the switch is receiving power. Check that at least one of the PSU LEDs on the front panel of the switch is

lit green. If no LEDs light, refer to the Hardware Reference for troubleshooting information.

Installation and Safety Guide

Connecting the Switch

Before you begin these procedures, ensure that the switch has at least one power supply unit installed and operating. Another power supply unit or a fan-only module must be installed in the other bay.

Using the CLI to configure a switch

1. Physically connect the terminal or PC to the ASYN0 port on the front

panel of the switch. For AT-8948 and AT-9900 switches, use the RJ-45 straight-through cable

that is supplied.

2. Set communication parameters on your terminal or terminal emulation program to the following:

•bit rate: 9600

• data bits: 8

•parity: None

• stop bits: 1

•flow control: Hardware

3. Check the power supply. For AC models, ensure that the switch is receiving power (PWR LED is lit

green). For DC models, ensure that the Run/Standby switch is in the On or Run

position and that the switch is receiving power (PWR LED is lit green).

4. Log in. After the switch has booted, the login prompt is displayed. If not, press the

Enter key two or three times. When the switch boots for the first time, it automatically creates an

account with manager privileges. The login name for the account is manager and the password is friend.

At the login prompt, enter the login name and password as follows:

The switch’s command prompt is displayed for you to use the CLI to configure it. Refer to the Software Reference for more information about configuring the software.

AT-8900, AT-9900, AT-9900s Series Switches

5. Change the password. Change the password as soon as possible because a manager account with

the default password is a serious security risk. Remember the new password because there is no way to retrieve it if you forget it.

To change the account password, use the set password command.

6. Display help for commands as necessary. To display a list of help topics, use the help command. To display help on a specific topic, use the help <topic> command. Alternatively, display a list of valid options by typing a question mark at the

end of a partial command.

Checking LEDs

Table 1 describes how LEDs on the switch report faults and operational activities.

Table 2 on page 14 describes how LEDs on power supply units and fan-only

modules report faults and operational activities.

LEDs for Ethernet ports and Small Form Factor Pluggable (SFP) ports are described in the Hardware Reference.

Table 1: System LEDs

LED State Description

PSU 1 Green PSU 1 is installed and supplying power to the switch.

The voltage output is within specification.

Red PSU 1 is installed in the switch and has exceeded its

recommended temperature threshold of 75º C (167º F), or the fan has failed.

A FOM is installed in the switch and has failed. The bay is empty.

Off A FOM is installed and operating at an acceptable

speed. For AT-9924T and AT-9924SP models, this LED is

always off because a FOM is not required.
