Power Supplies
x930 Series Installation Guide for Stand-alone Switches
There are five power supply models for the x930 Series switches. The
models are listed here:
AT-PWR150
AT-PWR250
AT-PWR250-80
AT-PWR800
AT-PWR1200
The top three models are primarily intended for the non-PoE AT-x93028GTX, AT-x930-28GSTX, and AT-x930-52GTX Switches. The bottom
two power supplies are for the PoE AT-x930-28GPX and AT-x930-52GPX
Switches.
Figure 5 illustrates the AT-PWR150 and AT-PWR250 Power Supplies.
The two power supplies are functionally identical.
Figure 5. AT-PWR150 and AT-PWR250 Power Supplies
The two power supplies are primarily designed for the non-PoE switches
and have these operating characteristics:
The power supplies provide system power, but no PoE power.
A single power supply can power an entire non-PoE switch.
Installing two power supplies in a switch adds power redundancy.
The power supplies are not recommended for the PoE AT-x930-
28GPX and AT-x930-52GPX Switches because they do not have
power for PoE devices. You may install them into PoE switches,
but the switches will not be able to support PoE powered devices.
25
Page 26
Chapter 1: Overview
The AT-PWR250-80 DC Power Supply illustrated in Figure 6 has the
same operating characteristics as the AT-PWR150 and AT-PWR250
Power Supplies. It, too, is intended for the non-PoE switches because it
can supply system power, but no PoE power. The only difference is that
this power supply has a DC wiring connector instead of an AC connector,
for DC wiring environments.
Figure 6. AT-PWR250-80 Power Supply
Figure 7 illustrates the AT-PWR800 Power Supply.This power supply is
primarily intended for the PoE AT-x930-28GPX and AT-x930-52GPX
Switches. It provides both system power to the switch as well as up to 380
watts of PoE power for the powered devices connected to the network
ports.

A PoE switch with one AT-PWR800 Power Supply has the following power
characteristics:

A switch with two AT-PWR800 Power Supplies has these power
characteristics:

Either 740 watts of PoE power or 380 watts of active PoE power
and 380 watts of redundant PoE power.
You may install the AT-PWR800 Power Supply in the non-PoE AT-x93028GTX and AT-x930-52GTX Switches. But because the switches do not
support PoE, the power supply will provide system power but no PoE
power.

x930 Series Installation Guide for Stand-alone Switches
The AT-PWR1200 Power Supply is shown in Figure 8. It is similar to the
AT-PWR800 Power Supply in that it is intended for the PoE AT-x93028GPX and AT-x930-52GPX Switches because it provides both system
power and power for PoE devices. The difference between them is the
amount of PoE power. The AT-PWR1200 Power Supply can provide up to
740 watts compared to 380 watts for the AT-PWR800 Power Supply.
Figure 8. AT-PWR1200 Power Supply
A PoE switch with one AT-PWR1200 Power Supply has the following
power characteristics:

740 watts of power for PoE devices
A switch with two AT-PWR1200 Power Supplies has these power
characteristics:
Full system power and redundant system power
Either 1440 watts of PoE power or 740 watts of active PoE power
and 740 watts of redundant PoE power.
Guidelines Please review the following guidelines concerning power supplies:
The x930 Series Switches do not come with power supplies. The
power supplies must be ordered separately.
If you install two power supplies in the switch, they must both be
the same model. For example, you may install two AT-PWR800
Power Supplies or two AT-PWR1200 Power Supplies in a switch.
You may not install two different power supply models in the
switch.
The non-PoE AT-x930-28GTX AT-x930-28GSTX, and AT-x930-
52GTX Switches require only one power supply for full operations.
Installing a second power supply adds power redundancy, which
protects against interruptions to network operations in the event
one power supply loses power or fails. Power redundancy is
available only when both AC or DC connectors on the switch are
connected to power sources.

Warning
Warning
Note
The PoE AT-x930-28GPX and AT-x930-52GPX Switches also
require only one power supply for network operations, excluding
PoE. The switches can continue to operate even if one power
supply fails or loses power.
The second power supply in the PoE switches either increases the
amount of power for PoE or adds PoE redundancy. For further
information, refer to “Power Budget” on page 33.
The DC wires for the AT-PWR250-80 DC Power Supply should be
routed from a DC load center containing appropriate overcurrent
branch protection for each DC feed, as required by the cognizant
local electrical authority.
Refer to “Technical Specifications” on page 149 for the input voltage
ranges.
Power cord is used as a disconnection device. To de-energize
equipment, disconnect the power cord. E3
This unit might have more than one power cord. To reduce the risk
of electric shock, disconnect all power cords before servicing the
unit. E30
The AT-PWR150, AT-PWR250, AT-PWR800, and AT-PWR1200
Power Supplies are powered on or off by connecting or
disconnecting the power cords. The AT-PWR250-80 Power Supply
is powered on or off with its On/Off power switch or by deactivating
the DC circuit.

10/100/1000Base-T Twisted Pair Ports
The twisted pair ports on the switches are described in this section.
Speed The ports can operate at 10, 100, or 1000 Mbps. The speeds may be set
manually using the management software or automatically with AutoNegotiation (IEEE 802.3u), the default setting.
The ports must be set to Auto-Negotiation to function at 1000 Mbps
and are not compatible with devices that are not IEEE 802.3u
compliant.
Duplex Mode The twisted pair ports can operate in either half- or full-duplex mode. The
duplex mode of a port, like port speed, may be set manually using the
management software or automatically with Auto-Negotiation (IEEE
802.3u), the default setting.
Wiring
Configuration
The speed and duplex mode settings of a port may be set independently
of each other. For example, a port may be configured such that its speed
is set manually while its duplex mode is established through AutoNegotiation.
A switch port should not use Auto-Negotiation to set its duplex mode
if it is connected to a network device that does not support AutoNegotiation for 10 or 100 Mbps operation and has a fixed duplex
mode of full-duplex. Otherwise, a duplex-mode mismatch may occur
in which a switch port and a network device operate at different
duplex modes. The duplex modes of switch ports that are connected
to network devices that do not support Auto-Negotiation should be
set manually through the management software.
The wiring configuration of a port operating at 10 or 100 Mbps can be MDI
or MDI-X. The wiring configurations of a switch port and a network device
connected with straight-through twisted pair cabling have to be opposite,
such that one device is using MDI and the other MDI-X. For instance, a
switch port has to be set to MDI-X if it is connected to a network device set
to MDI.
You may set the wiring configurations of the ports manually or let the
switch configure them automatically with auto-MDI/MDI-X (IEEE 802.3abcompliant). This feature enables the switch to automatically negotiate with
network devices to establish their proper settings.

Power Over Ethernet
The AT-x930-28GPX and AT-x930-52GPX Switches feature Power over
Ethernet (PoE) on the 10/100/1000Base-T ports. PoE is used to supply
power to network devices over the same twisted pair cables that carry the
network traffic.
The main advantage of PoE is that it can make it easier to install a
network. The selection of a location for a network device is often limited by
whether there is a power source nearby. This often limits equipment
placement or requires the added time and cost of having additional
electrical sources installed. But with PoE, you can install PoE-compatible
devices wherever they are needed without having to worry about whether
there are power sources nearby.
A device that provides PoE to other network devices is referred to as
power sourcing equipment (PSE). The AT-x930-28GPX and AT-x93052GPX Switches act as PSE units by adding DC power to the network
cable, thus functioning as a central power source for other network
devices.
x930 Series Installation Guide for Stand-alone Switches
Devices that receive their power from a PSE are called powered devices
(PD). Examples include wireless access points, IP telephones, webcams,
and even other Ethernet switches.
The switch automatically determines whether or not a device connected to
a port is a powered device. Ports that are connected to network nodes that
are not powered devices (that is, devices that receive their power from
another power source) function as regular Ethernet ports, without PoE.
The PoE feature remains activated on the ports but no power is delivered
to the devices.
PoE Standards The AT-x930-28GPX and AT-x930-52GPX Switches support these PoE
standards:
PoE (IEEE 802.3af): This standard provides up to 15.4 watts at the
switch port to support powered devices that require up to 12.95
watts.
PoE+ (IEEE 802.3at): This standard provides up to 30.0 watts at
the switch port to support powered devices that require up to 25.5
watts.
Powered Device
Classes
Powered devices are grouped into the five classes listed in Table 3 on
page 32. The classes are based on the amount of power the devices
require. The switches support all five classes.

Power Budget The power budget is the maximum amount of power the switch can supply
to the powered devices on its ports. The higher the budget, the more PoE
devices the switch can support at one time.
The power budgets of the AT-x930-28GPX and AT-x930-52GPX Switches
depend on several factors. The first is the power supply model. The po wer
budgets of the five power supplies are listed in Table 6.
Table 6. Power Supply Budgets of the Power Supplies
Power Supply Power Budget for PoE Devices
AT-PWR150 0 watts
AT-PWR250 0 watts
AT-PWR250-80 0 watts
AT-PWR800 380 watts
AT-PWR1200 740 watts
33
Page 34
Chapter 1: Overview
Note
The AT-PWR250 and AT-PWR250-80 Power Supplies are intended
for the non-PoE AT-x930-28GTX, AT-x930-28GSTX, and AT-x93052GTX Switches. They are not intended for the AT-x930-28GPX
and AT-x930-52GPX Switches because they do not provide power
for PoE + devices. You may install them in the PoE+ switches, but
the switches will not support PoE devices.
Another factor that determines the power budget of the switch is the
number of PoE power supplies in the device. The power budget of a PoE
switch that has only one PoE power supply is equal to the budget of the
power supply. For example, a switch that has one AT-PWR1200 Power
Supply has a power budget of 740W for powered devices.
A PoE switch with two AT-PWR800 or AT-PWR1200 Power Supplies has
either redundant PoE power or nearly double the power budget. This is
controlled by the power boost feature, which has a status of either enabled
or disabled. When the power boost feature is enabled, a PoE switch with
two power supplies actively uses the PoE power from both supplies to
increase its available power budget. When the feature is disabled, the
switch uses the PoE power of only one of its power supplies and keeps the
other in reserve in case the primary power supply should fail or lose
power.
As an example, assume that a PoE switch has one AT-PWR1200 Power
Supply, which has a power budget of 740W for powered devices. Thus,
the switch would have a total power budget of 740W. Now assume the
switch has two AT-PWR1200 Power Supplies. When the power boost
mode is enabled, the switch uses the PoE power from both supplies, for a
total power budget of 1440W. When the power boost mode is disabled,
the switch has an active PoE power of 740W and a redundant budget of
the same amount. The switch activates the redundant power budget only if
the power supply providing the active power budget fails or loses power.
Table 7 lists the power budgets for the switch with one or two AT-PWR800
Power Supplies and the power boost mode.

The maximum number of PoE devices the switch can support at one time
is determined by its power budget and the power requirements of the
devices. The switch can supply power to all of the devices as long as the
their total power requirements is less than its power budget. If the switch
determines that the power requirements of the devices exceed its power
budget, it denies power to one or more ports using a mechanism referred
to as port prioritization.
Port
Prioritization
To determine whether the power requirements of the PoE devices you
plan to connect to the switch exceed its power budget, refer to their
documentation for their power requirements and add the requirements
together. The switch should be able to power all of the devices
simultaneously as long as the total is below its power budget. If the total
exceeds the available power budget, you should consider reducing the
number of PoE devices so that all of the devices receive power.
Otherwise, the switch powers a subset of the devices, based on port
prioritization.
The switch can handle different power requirements on different ports.
This enables you to connect different classes of PoE equipment to the
ports on the switch.
If the power requirements of the powered devices exceed the switch’s
power budget, the switch denies power to some ports based on a system
called port prioritization. You may use this mechanism to ensure that
powered devices critical to the operations of your network are given
preferential treatment by the switch in the distribution of power should the
demands of the devices exceed the available capacity.
There are three priority levels:
Critical
High
Low
35
Page 36
Chapter 1: Overview
Ports set to the Critical level, the highest priority level, are guaranteed
power before any of the ports assigned to the other two priority levels.
Ports assigned to the other priority levels receive power only if all the
Critical ports are receiving power. Ports that are connected to your most
critical powered devices should be assigned to this level. If there is not
enough power to support all the ports set to the Critical priority level,
power is provided to the ports based on port number, in ascending order.
The High level is the second highest level. Ports set to this level receive
power only if all the ports set to the Critical level are already receiving
power. If there is not enough power to support all of the ports set to the
High priority level, power is provided to the ports based on port number, in
ascending order.
The lowest priority level is Low. This is the default setting. Ports set to this
level only receive power if all of the ports assigned to the other two levels
are already receiving power. As with the other levels, if there is not enough
power to support all of the ports set to the Low priority level, power is
provided to the ports based on port number, in ascending order.
Wiring
Implementation
Power allocation is dynamic. Ports supplying power to powered devices
may cease power transmission if the switch’s power budget is at
maximum usage and new powered devices, connected to ports with
higher priorities, become active.
The IEEE 802.3af standard defines two methods for the delivery of DC
power over twisted pair cable by a switch to the powered devices. These
methods, known as modes A and B, identify the wires within the cable that
carry the DC power from the switch to a powered device.
Twisted pair cabling typically consists of eight wires. With 10Base-T and
100Base-TX devices, the wires connected to pins 1, 2, 3, and 6 on the RJ45 connectors carry the network traffic while the wires connected to pins 4,
5, 7, and 8 are unused. With 1000Base-T devices, all eight wires are used
to carry network data.
It takes four wires to deliver DC power to a powered device. With Mode A,
the power is delivered on pins 1, 2, 3, and 6. These are the same pins in
10Base-T and 100Base-TX devices that carry the network data. With
mode B, the power is provided over the spare wires.
The ports on the AT-x930-28GPX and AT-x930-52GPX Switches deliver
the power using pins 1, 2, 3, and 6, which corresponds to mode A in the
IEEE 802.3af standard. Powered devices that comply with the IEEE
802.3af standard are required to support both power delivery methods.
Legacy devices that do not comply with the standard will work with the
switch if they are powered on pins 1, 2, 3, and 6.

SFP Slots
x930 Series Installation Guide for Stand-alone Switches
The twenty four SFP slots on the AT-x930-28GSTX Switch support the
following types of transceivers:
100Base-FX, 1000Base-T, and 1000Base-SX/LX SFP transceivers
Single-port BiDi 100Base-FX and 1000Base-LX SFP transceivers
1000Base-ZX SFP transceivers
The slots are paired with the twenty four 10/100/1000Base-T twisted pair
ports. SFP slot 1 is paired with twisted pair port 1R, slot 2 with twisted pair
port 2R, and so on. Only one slot or port in a pair can be active at a time.
For example, if you install an SFP transceiver in slot 3 and connect it to an
active network device, the switch deactivates twisted pair port 3R.
Please review the following guidelines for using the SFP slots on the ATx930-28GSTX Switch:
Each SFP slot is paired with a twisted pair port.
You may not change the pairings of the ports and slots.
Only one port or slot in a pair can be active at a time.
The twisted pair port is the default active port of a pair.
An SFP slot automatically becomes active when you install and
connect an SFP transceiver to an active network device.
The switch automatically reactivates the twisted pair port of a pair
when the transceiver in the corresponding SFP slot loses its link to
a remote network device. For example, the switch reactivates
twisted pair port 4R if you disconnect the fiber optic cable from a
transceiver in slot 4.
The letter “R” in the numbering of the twisted pair ports on the front
of the switch refers to the “redundant” function of the ports. The
twisted pair ports are only available when their corresponding SFP
slots are empty or the SFP transceivers have not established links
with network devices.

The SFP+ slots do not support 100Mbps 100Base-FX transceivers.
The slots support full-duplex mode only.They do not support halfduplex mode.
SFP and SFP+ transceivers must be purchased separately.
SFP+ slots 27/S1 and 28/S2 on the AT-x930-28GTX, AT-x93028GSTX, and AT-x930-28GPX Switches and slots 51/S1 and 52/S2
on the AT-x930-52GTX and AT-x930-52GPX Switches are initially
configured as stacking slots for the VCStack feature. If you intend to
use the switch as a stand-alone unit, you must disable the VCStack
feature before you can use the slots with standard SFP or SFP+
transceivers. The configuration instructions are provided later in this
guide, in Chapter 10, “Configuring the Switch for Stand-alone
Operation” on page 125.

Stacking S1 and S2 SFP+ Slots
Note
Note
As explained in the previous section, you may use the four SFP+ slots on
the front panel of the switch with SFP 1000Mbps or SFP+ 10Gbps
transceivers to add high speed links from the switch to other network
devices. However, SFP+ slots 27/S1 and 28/S2 on the 28-port switches
and slots 51/S1 and 52/S2 on the 52-port switches have an additional
function. They can also be used with SFP+ transceivers and the VCStack
feature to build a stack of up to eight switches. The switches of a VCStack
act as a single virtual unit. They synchronize their actions so that switching
operations, like spanning tree protocols, virtual LANs, and static port
trunks, span across all of the units and ports. The two main advantages of
stacks are listed here:
You can manage multiple units simultaneously, which can simplify
network management.
You have more flexibility in how you configure some of the
features. For instance, a static port trunk on a stand-alone switch
has to consist of ports from the same switch. In contrast, a static
trunk on a stack may consist of ports from different switches in the
same stack.

SFP+ slots 27/S1 and 28/S2 on the 28-port switches and slots 51/S1
and 52/S2 on the 48-port switches are initially configured as stacking
slots for the VCStack feature. If you intend to use the switch as a
stand-alone unit, you must disable the VCStack feature before you
can use the slots with standard SFP or SFP+ transceivers. The
configuration instructions are provided later in this guide, in Chapter
10, “Configuring the Switch for Stand-alone Operation” on page 125.
This guide explains how to install the devices as stand-alone units.

Chapter 1: Overview
Ethernet Management Port (NET MGMT)
The NET MGMT port in the management panel of the switch is a separate
routed eth0 interface. The interface is not part of the switching matrix of
the Ethernet line cards, but the CPU on the controller card can route traffic
in or out of the port from the line cards.
Here are the guidelines to using the port:
The port should only be used for initial configuration and
maintenance access to the chassis.
The NET MGMT port has a standard RJ-45 8-pin connector and
operates at 10, 100, or 1000 Mbps in either half- or full-duplex
mode.
The cable requirements for the port are the same as for the 10/
100/1000-T ports, listed in Table 2 on page 30. For the port
pinouts, refer to “RJ-45 Twisted Pair Port Pinouts” on page 156.
NET MGMT
LEDs
The default setting for the port is Auto-Negotiation, which sets the
speed and duplex mode automatically. You may disable AutoNegotiation and configure the port manually.
The wiring configuration of the NET MGMT port is set
automatically with automatic MDIX detection. You may disable
automatic MDIX detection and set the wiring configuration
manually.
The port is referred to as eth0 in the management software.
For instructions on how to configure the NET MGMT port, refer to the
Software Reference for x930 Series Switches.
The Network Management (NET MGMT) port on the switch has two

eco-friendly Button
Note
x930 Series Installation Guide for Stand-alone Switches
The eco-friendly button on the front panel of the switch is used to toggle
the port LEDs on or off. You might turn off the LEDs to conserve electricity
when you are not monitoring the device. You can also toggle the LEDs
with the ECOFRIENDLY LED and NO ECOFRIENDLY LED commands in
the Global Configuration mode of the command line interface. The switch
is said to be operating in a low power mode when the LEDs are turned off.
Operating the switch in the low power mode with the LEDs turned off does
not interfere with the network operations of the device.
The management software on the switch has a command that blinks the
LEDs so that you can quickly and easily identify a specific unit among the
devices in an equipment rack. It is the FINDME command. The command
works on the switch even if you turned off the LEDs with the eco-friendly
button or NO ECOFRIENDLY LED command.
The Switch ID LED is always on, but it displays different information
depending on whether the LEDs are on or off. When the LEDs are on, the
ID LED displays the ID number of the switch. When the switch is operating
in the low power mode with the LEDs off, the ID LED indicat es whether the
switch is a stand-alone unit or the master or member switch of a VCStack,
as detailed in Figure 15 on page 49.
Before checking or troubleshooting the network connections to the
ports on the switch, you should always check to be sure that the
LEDs are on by either pressing the eco-friendly button or issuing the
ECOFRIENDLY LED and NO ECOFRIENDLY LED commands in
the Global Configuration mode of the command line interface.

Console Port
Note
x930 Series Installation Guide for Stand-alone Switches
You use the Console port to manage the switch and configure its features
and parameter settings. This type of management uses serial RS-232 and
is commonly referred to as local management because it is not conducted
over your network. To perform local management, you must be at the
location of the switch and use the management cable included with the
device.
To establish a local management session with the switch, you have to
connect a terminal or a personal computer with a terminal emulation
program to the Console port, which has an RJ-45 style (8P8C) connector,
using the provided management cable. The cable has RJ-45 style (8P8C)
and DB-9 (D-sub 9-pin) connectors.
The Console port is set to the following specifications:
Default baud rate: 9600 bps (Range is 9600 to 115200 bps)
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
These settings are for a DEC VT100 or ANSI terminal, or an

Choosing a Site for the Switch
Warning
Observe these requirements when planning the installation of the switch.
If you plan to install the switch in an equipment rack, check to be
sure that the rack is safely secured so that it will not tip over.
Devices in a rack should be installed starting at the bottom, with
the heavier devices near the bottom of the rack.
If you plan to install the switch on a table, check to be sure that the
table is level and stable.
The power outlet should be located near the switch and be easily
accessible.
The site should allow for easy access to the ports on the front of
the switch, so that you can easily connect and disconnect cables,
and view the port LEDs.
The site should allow for adequate air flow around the unit and
through the cooling vents on the front and rear panels. (The
ventilation direction in units that have a cooling fan is from front to
back, with the fan on the back panel drawing the air out of the unit.)

the wall.
Step 2: Install the
switch on the
plywood base.
Wall
Plywood
Base
Wall Studs
The plywood base allows you to mount the switch on two wall studs. If you
install the switch without the base, only one side of it would be attached to
a stud. This is because the standard distance between two studs in a wall
is 41 centimeters (16 inches) while the distance between the left and right
brackets on the switch is 36.2 centimeters (14 1/4 inches).
The recommended minimum dimensions of the plywood base are listed
here:
Width: 58.4 centimeters (23 inches)
Height: 55.9 centimeters (22 inches)
Thickness: 5.1 centimeters (2 inches)
The dimensions assume the wall studs are 41 centimeters (16 inches)
apart. You may need to adjust the width of the base if the distance
between the studs in your wall is different than the industry standard.
You should install the plywood base to the wall and then install the switch
on the base. Refer to Figure 47.
