Redundant Power Supply Modules

The Switch is equipped with a single DES-7011 RPS unit. Up to three power supply units can be
installed on the switch chassis. As network modules are added to the chassis, RPS units can be
added for better load balancing and increased RPS lifespan. Two RPS units must be used for full
loading operation of the Switch. Refer to the power consumption per module data in the table below.

DES-7011 RPS Unit

§ One plus two power module design (one pre-installed)

§ Each RPS unit supports up to 730 Watts (see power consumption information below)

§ Current sharing/ load balancing design

§ Full redundant feature design to ensure continuous operation

§ Hot-swappable

§ Power management functions enabled

Use this table to calculate total power consumption for the Switch chassis. Do not exceed the 730 Watt
maximum for each RPS unit. For best load balancing performance and RPS lifespan it is
recommended to allow for redundancy. Two RPS units must be used for full loading operation of the
Switch, for these installations, an additional third RPS unit is also recommended for redundancy.

You may install DES-7000 series network modules at any time before or after the switch has been

installed and powered on. Modules can be hot swapped to meet the changing demands of the network.

Attaching Wheels

The DES-7000 is shipped with four wheels that may
be install but are not required. To install the wheels,
gently place the chassis on either of its sides to
access the wheel mounts. Make sure the fan module
is firmly in place before tilting the chassis. Each
wheel is held in place with four screws (included in
the package with the wheels).

Rack Installation

The chassis may be placed into a standard 19”
equipment rack with or without the wheels attached.
The ears at the front of both sides of the chassis
should be used to hold it firmly in place with screws.

Installing Modules

The DES-7000 and DES-7100 Switch chassis’ has one DES-7003 management/uplink module
installed when shipped. In order to use other available modules you will need to install them. Follow
the instructions below. Modules can be installed into any free slot, except the CPU module.

WARNING

When handling Switch modules be sure to wear an ESD wrist
strap or suitable grounding device to prevent damage from
electrostatic discharge. Do not attach the strap to any part of the
power supply if the Switch is powered on.

To install a module, follow these steps:

WARNING

When using an ESD wrist strap or other grounding device, do not
attach it to any part of the power supply if the switch is powered
on.

1. Remove the faceplate from the slot intended for module insertion. Keep the faceplate in case it
is needed in the future.

2. Carefully remove the module from its packaging.

3. Line up the module with the grooved slot guides and insert it into the chassis. It should glide
easily toward the back of the chassis. Push it in until the module ejector levers are in contact
with the chassis. Be careful not to bend the circuit board of the module. Modules for the DES­7000 should be oriented so the model number of the module is at the top and the LED
indicators are on the bottom. Modules installed in the DES-7100 should be inserted
horizontally in the upright position, that is, so the model number and LED indicator labels are
displayed so they can be read from left to right.

4. Push the ejector levers toward the center of the module until they touch the front of the module.
This will push the bus connectors into backplane of the chassis.

5. Hand-tighten the installation screws at each end of the module. The module is now firmly
seated in the backplane of the chassis.

Removing a Module

To remove a module from the chassis follow these steps:

WARNING

When using an ESD wrist strap or other grounding device, do not
attach it to any part of the power supply if the switch is powered
on.

1. Loosen the two installation screws on the front of the module.

2. Pull the ejector levers out and away from the center of the module front panel. This will pull the
module out of the backplane.

3. Cover the empty slot with a faceplate that was shipped with chassis.

Power on the Switch

The Switch is shipped with two DES-7011 RPS modules installed and is therefore ready to be
powered on after you have assembled the hardware. Follow these steps to power on the Switch:

1. Plug the device end of either power cord into either power supply.

2. Plug the outlet end of the power cord into a suitable AC power source.

3. Observe the LED indicators to make sure the Switch is functioning normally.

Upon powering on the LED indicators on the DES-7003 management/uplink module should operate as
follows:

§ All indicators will flash momentarily indicating a system reset.

§ The Power indicator will flash for a few seconds during the POST

§ The System Status LED indicator will be dark during CPU arbitration for several

seconds

The System Status and Power LED indicators will light steady green indicating normal system and
power supply function. An amber light in either of these indicates a problem.

Power Failure

As a precaution, the Switch should be unplugged in case of an impending power failure. When power
is resumed, plug the Switch back in.

Battery Back Up System

The DES-7000 and DES-7100 can be equipped with a battery back up system. Battery back ups may
only be installed by qualified technicians. Please contact your vendor for information on purchasing
and installing such a system.

Hot Swap Procedure for Switch Modules

All switch modules including the Primary Master and Primary Back Up CPU modules can be changed
while the Switch is powered on. Follow the procedures listed here to remove a module or to insert a
module while the Switch is powered on. Changing a module while the Switch is operating is commonly
called “hot swapping” which is the term we use in this document.

WARNING

When handing Switch modules be sure to wear an ESD wrist
strap to prevent damage from static electric discharge. Do not
attach the strap to any part of the power supply if the Switch is
powered on.

Hot Swap Removal of a Switch Module

Remove a single switch module following the procedure listed below. Only one module should be
removed at a time. Wait for the process to be completed before removing (or inserting) another
module. Wear an ESD wrist strap to prevent damage to the module from possible static electric
discharge.

To perform a hot swap removal of a switch module follow these steps:

1. Gently depress the Hot Swap button on the front panel of the module you want to remove.
The Hot Swap button is located between the Per Port Link LED indicators and the Power and
Hot Swap Status indicators. The button can be pressed using your finger, a ballpoint pen or
other suitable instrument.

2. Observe the Hot Swap & Card Status LED indicator on the switch module being removed. It
should blink amber. During this phase the module is sending a message to the master (CPU)
module that a removal has been initiated.

3. The master module detects the removal and updates its database. The master module cuts
power to the switch module being removed. The Power LED indicator and all other LED
indicators on the switch module will go dark.

4. When you see that the switch module has been powered off you may remove it. Unscrew the
installation screws and pull both ejector levers toward the center of the front panel of the
module to unseat it from the backplane of the Switch.

5. If the module is not being reinserted, completely remove it from the slot. It should slide out
easily in the guides. Be sure to properly store the module.

6. If you do not intend to install another module in the vacant slot, cover it with one of the slot
faceplates included with the original shipment.

Note

When performing a hot swap of a Master CPU module the
procedure is essentially the same as a hot swap of other switch
modules. The procedure for removing a Primary Master CPU
module is slightly different since the designation of Primary
Master must be transferred to the current Back Up Master before
the unit is powered off. This takes a few seconds. The Master
LED Indicator will light on the new Primary Master CPU module
indicating that the unit is the active master. The former Primary
Master module is powered off and may then be removed.

Hot Swap Insertion of a Switch Module

Follow the procedure listed below to insert a new switch module into an available slot while the Switch
is powered on. Only one module should be inserted at a time. Wait for the process to be completed
before inserting or removing another module. Wear an ESD wrist strap to prevent damage to the
module from possible static electric discharge.

1. If the slot is covered with a faceplate, remove and save it for later use.

2. Carefully remove the module from its packaging.

3. Line up the module with the grooved slot guides and insert it into the chassis. It should glide
easily toward the back of the chassis. Push it in until the module ejector levers are in contact
with the chassis. Be careful not to bend the circuit board of the module. Modules for the DES­7000 should be oriented so the model number of the module is at the top and the LED
indicators are on the bottom.

4. Push the ejector levers toward the center of the module until they touch the front of the module.
This will push the bus connectors into backplane of the chassis.

5. Observe the Hot Swap & Card Status LED indicator on the switch module. This will blink
amber for about 13 seconds after being inserted. During this time the CPU is recognizing the
new switch module and the switch module is booting. A steady amber light indicates a system
failure.

6. A steady green Hot Swap & Card Status LED indicator on the switch module indicates the
module is ready and running normally. The master (CPU) module recognizes the new switch
module.

7. Hand-tighten the installation screws at each end of the module. The module is now firmly
seated in the chassis and powered on. This completes the hot swap insertion.

Hot Swap Procedure for Fan Tray Module

CAUTION

The Fan Tray Module can be replaced with the power on. If you
cannot replace the fan tray immediately (within two minutes) the
Switch chassis should be powered off to avoid damage from
overheating before the fan tray is removed.

Changing the fan tray module for the DES-7000 and DES-7100 is a simple procedure however if you
choose to do this while the Switch is powered on, be sure to have the replacement fan tray ready at
hand so the procedure can be completed as quickly as possible. It is not necessary to initiate the hot
swap procedure, the Master CPU will be aware of fan tray removal and insertion. Removal of the fan
tray will trigger the system alert buzzer and the Fan Fail LED indicator. Be sure to use proper ESD
grounding procedures to avoid electrostatic discharge. The procedure below describes this procedure
and changes to the LED indicators that occur.

WARNING

The fans will continue rotating for several seconds after power to
the unit is cut off. Use only the handle on the front of the fan tray
when removing the device to avoid risk of injury.

Inserting the fan tray into the DES-7100 chassis

To change the fan tray:

1. Unscrew the installation screws on each side of the module and pull the module from out of
the chassis. Be careful not to drop the fan tray when removing it.

2. Replace the fan tray module immediately if the Switch is powered on; insert the new unit using
the guides built into the chassis. It should glide easily into position if it is properly lined up.

3. Push the module toward the backplane of the chassis until the front of the module is flush with
the front panel of the chassis. You will need to apply firm pressure for about the last half
centimeter to establish the contacts and firmly position the unit in the backplane.

4. The fan tray will power on and be recognized by the Master CPU. You should see the Hot
Swap & Card Status LED indicator on the Master CPU module blink for about 13 seconds
while the unit is recognized.

Tighten the installation screws on the fan tray module. Observe the Fan/Fail LED indicator on the
Master CPU module to make sure it is functioning normally: dark for normal function, blinking amber if
there is a problem. The unit is now completely installed.

Push Buttons

Two recessed push buttons are visible on the front panel of the DES-7003 CPU module a System
Buzzer and Hot Swap button. Each switch module, including DES-7003 CPU modules, has a Hot
Swap push button.

Push buttons are recessed to avoid accidental activation. They can be activated by gently depressing
them with a ballpoint pen or other suitable instrument. The functions activated by the buttons are
described as follows:

• System Buzzer (DES-7003 CPU modules only) A warning sounds when any system fans fail
or when the fan tray unit has been removed. Depressing the System Buzzer button will silence
the fan fail alarm.

Hot Swap This is used to initiate a hot swap of the module (See the section on hot swapping modules
below).

Fans

For the DES-7000 chassis, there are a total of 8 system fans arranged on two plains. At the top of the
backside of the Switch chassis are four fans (dimensions = 92 x 92 x 25 mm) arranged in a single
horizontal row spanning the width of the Switch. The upper fans run any time power is supplied to the
chassis. The remaining 4 fans (dimensions = 172 x 150 x 51 mm) are located in a separate slide-in fan
tray module oriented horizontally below the module slots. The fan tray fans are positioned to maintain
adequate airflow between installed switch modules. The fan tray fans are power on or off as needed
automatically by the CPU using temperature information from built-in sensors.

The DES-7100 has a fan tray module with 6 fans (dimensions = 80 x 80 x 20 mm) oriented vertically
on the right side of the switch chassis. The fan tray fans power on or off as needed automatically by
the CPU using temperature information from built-in sensors. Fan trays may be replaced from the front
of the chassis while the switch is powered on.

System fan failure can result in one or all modules being powered down. The shutdown sequence is as
follows:

□ If two fans fail, all slave modules and the backup Master will be powered off after 30 minutes if

not replaced.

□ If three fans fail, all slave modules and the backup Master will be powered off after 10 minutes.
□ If four fans fail, all slave modules and the backup Master will be powered off after 5 minutes.

Network Cabling and Connections

This chapter describes cabling and connectors used to connect the module to a network and using the
LED indicators to evaluate network function.

Connect to the DES-7003 CPU Management/Uplink Module

The DES-7003 module has six Gigabit Ethernet port to uplink the Switch as well as two ports, a
Console port and an SNMP port, used for device management.

§ GBIC Uplink ports – Install 1000BASE-SX or 1000BASE-FX GBIC plug-in module. These
ports are used to link the Switch to the network backbone.

§ Console port – Use this for an out-of-band connection to manage the Switch. Connection
requires the RJ-45 to RS-232 serial adapter included with the Switch and an Ethernet cable.
Connect this directly to the serial port on a computer used for managing the Switch.

§ Mgmt port – This port is for out-of-band management of the Switch using either Telnet or web-
based management. The Switch can be connected directly to a computer with standard
Ethernet cable to the Ethernet port on a computer.

Connect to the DES-7005 10BASE-T/100BASE-TX Module

Network connections to the 24 ports of the Ethernet module are made using Category 5 or better
cabling with RJ-45 UTP connectors. Ports may be connected to network devices that support
10BAES-T or 100BASE-TX operation. All ports support auto-negotiation by default for speed, duplex
and flow control (in Full duplex mode). All ports are configurable to force different speed, duplex and
flow control operation. All ports supports auto-detection of polarity and adjust for MDI/MDI-X
connectors to establish a valid link.

The per port LED Link indicators on the DES-7005 will:

§ Light green when a link has been established

§ Blink green when there is activity in the port

§ Remain dark when there is no link

Connect to the DES-7006 100BASE-FX Module

Network connections to the 24 ports of the 100BASE-FX module are made using single multimode
fiber (SMF/MMF) optic cabling with SFF (LC Duplex) type connectors.

The per port LED Link indicators on the DES-7006 will:

§ Light green when a link has been established

§ Blink green when there is activity in the port

§ Remain dark when there is no link
