x900 Series Switch and SwitchBlade® x908

Selecting a Site

Before you install the switch, review the following considerations about its location.

■AT-8948, x900-48FE, x900-48FS, and AT-9900 switches require an ambient temperature from 0ºC to 50ºC (32ºF to 122ºF).

■AT-9924Ts, x900-12XT/S, x900-24XT, x900-24XT-N, x900-24XS, and SwitchBlade x908 switches require an ambient temperature from 0ºC to 40ºC (32ºF to 104ºF).

■There should be adequate airflow around the switch and its vents.

■The site should be dust-free and without moisture.

■Humidity can be from 5% to 80% non-condensing.

■You need a reliable and earthed (grounded) power supply source, preferably dedicated and filtered.

■Cabling must not be exposed to sources of electrical noise, such as radio transmitters, broadband amplifiers, power lines, electric motors, and fluorescent fixtures.

■Switch ports are suitable for intra-building connections, or where non-exposed cabling is required.

■Related network devices can be connected to the switch but cannot exceed maximum cable lengths specified in the Hardware Reference.

■You may need to remove cabinet doors from the equipment rack to accommodate cords and cables.

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

■The SwitchBlade x908 should only be installed in locations where access to the system is controlled. The SwitchBlade x908 is not intended for home use. If installed in a school, it should only be installed in a location restricted to service personnel.

Installation and Safety Guide

Installing the Switch

Ports on the switch are suitable only for connections within buildings (intrabuilding) and with cables unexposed to the outside.

You can install the switch on a level surface, such as a desktop or bench, or in a standard 19-inch rack. Some switches are heavier at the rear than at the front. Use the brackets supplied with the switch when rack-mounting because they are designed to fully support the weight.

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 www.alliedtelesis.com/support/software.

■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:

•Phillips #2 screwdriver to loosen the blanking plate, if any.

•Rack-mount screws and nuts, and a suitable screwdriver. The SwitchBlade x908 requires eight sets of screws and nuts. All other switches required four sets.

•For DC installations, you need an appropriate DC power source, DC supply cable, ring connectors, and a crimp tool for screw terminal style connectors or appropriate connectors for the PSU model.

■Prepare the cabinet in a suitable location

Follow guidelines described in “Selecting a Site” on page 6 to choose an appropriate location and modify the rack as necessary.

■Because the switch is deep, we recommend two people mount the switch in the rack and tighten the screws.

Preparation for NEBS

For Network Equipment Building System (NEBS) installations of the x900-24XT-N, do the following to ensure rack-mounted installations are earthed:

■Remove non-conductive coatings, such as lacquer and enamel, from the rack rail where hardware will contact it. Remove coatings from unplated connectors, braided strap, and bus bars, and bring them to a bright finish. Coat them with an antioxidant before connecting them. During installation, thread-forming screws with star washers may be used for this purpose.

x900 Series Switch and SwitchBlade® x908

■All bare conductors must be coated with an appropriate antioxidant compound before making crimp connections.

Warning Both AC and DC versions of this equipment must be earthed through the power cables provided.

On a level surface

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

If you have not already done so, review considerations in “Selecting a Site” on page 6.

2.Unpack the switch.

3.Fit rubber feet, if supplied.

All models except the SwitchBlade x908 ship with rubber feet. They stop the switch from slipping and protect the surface from scratches. The x900-12XT/S switch has four feet. All other models have five feet. Using the screws provided, screw the rubber feet in the holes on the underside of the switch. Use the following diagram to locate the screw holes. For the x900-12XT/S, use positions 1, 2, 3, and 5.

4.Place the switch in the desired location for operation.

Installation and Safety Guide

In a 19-inch rack

1.Ensure the rack has sufficient space for the switch and its cables. For the switch’s requirements, see “Selecting a Site” on page 6.

2.Install cage nuts at the front of the rack so they are ready for the rackmount screws in the following steps.

3.Unpack the switch.

It may be helpful to temporarily remove any PSU or FOM so that the switch is lighter and easier to manipulate during installation. For more information, see the Removable Power Supply and Fan Installation Guide.

4.Screw one bracket to each side of the switch using the M4 screws provided.

On the x900-12XT switch, you can use the alternative set of holes on the rack mount bracket to mount the switch further back in the rack.

For NEBS ensure the rack and hardware have been pre-treated, as described in “Preparation for NEBS” on page 7.

5.Mount the switch into the rack from the front, and tighten the rack-mount screws.

Two people are required at this point. One person can lift the switch into the rack and attach it to the front rails while the second person safely supports it from the rear.

Installation and Safety Guide

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 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 x900-24 models, when using an AT-PWR01 AC power supply and an AT-PWR01 DC power supply in the same switch, then the ground-terminal of the DC power connector must be connected to the same ground as the AC ground pin of the AC power connector.

If this is not possible, then you must ground the AT-PWR01 AC only, and leave the AT-PWR01 DC power connector ungrounded. In this case, as a safety precaution, ensure that the rack is also grounded.

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.

Warning When SBx908 devices 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, the wires of each grounding cable must be 18AWG or thicker.

x900 Series Switch and SwitchBlade® x908

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 or an AT-PWR05 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.

Warning In order to avoid damaging the PSU, make sure that the PSU terminals are wired to the correct polarity.

•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 18AWG or thicker.

•All grounding points are at the same ground level. That is, all power connectors share a common power distribution unit.

Warning When mounting one or two AT-PWR01 DC PSUs to a grounded rack, ensure that the ground level of the rack and the DC power connector are the same.

If this is not possible, then you must ground the AT-PWR01 AC only, and leave the AT-PWR01 DC power connector ungrounded. In this case, as a safety precaution, ensure that the rack is also grounded.
