Chassis Controls and LEDs
2.1
Chassis Controls and LEDs
The Reset/Force PROM button shown in Figure 2-2 is the only chassis control
and is used to recover a disabled switch. The chassis LEDs provide information
about the switch’s operation status. These LEDS include the Over Temperature
LED, Fan Fail LED, Heartbeat LED, and the Input Power LED. To apply power to
the switch, plug the power cord into the switc h AC power receptacle and into a
110 or 230 VAC power source.

2.1.1
Reset/Force PROM Button
The Reset/Force PROM button is a dual-function momentary switch on the front
panel. Its purp ose is to reset the switch or to place the switch in force PROM
mode. Force PROM mode causes the switch to access PROM when flash
memory or the resident configuration file is corrupted. Placing the switch in force
PROM mode forces the default IP address of 10.0.0.1. To exit force PROM mode,
reset the switch either by pressing the Reset/ Force PROM button or power cycling
the switch. Refer to ”Recovering a Switch” on page 5-6 for more informatio n about
using force PROM mode.

2.1.1.1
Resetting a Switch
To reset the switch, use a pointed tool to press and release (less than 4 seconds)
the Reset/Force PROM button. The switch will respond as follows:
1. All of the chassis LEDs will illuminate and then extinguish leaving only the
Input Power LED illuminated.
2. After approximately 1 minute, the power-on self test begins illuminating all
chassis LEDs.
3. When the POST is complete, the chassis LEDs extinguish leaving the Input
Power LED illuminated and the Heartbeat LED flashing once per second.
2.1.1.2
Placing the Switch in Force PROM Mode
To place the switch in force PROM mode, do the following:
1. Isolate the switch from the fabric.
2. Press and hold the Reset/Force PROM button with a pointed tool for about 4
seconds. When the Input Power LED alone is illuminated, release the
button.

Chassis Controls and LEDs
3. After approximately 1 minute, the power-on self test begins illuminating all
chassis LEDs.
4. When the POST is complete, the chassis LEDs extinguish leaving the Input
Power LED and the Heartbeat LED illuminated. The Heartbeat LED
illuminates continuously while the switch is in force PROM mode.
To exit force PROM mode and return to normal operation, reset the switch.
2.1.2
Over Temperature LED (Yellow)
The Over Temperature LED provides status infor mation about the ai r t emperature
inside the switch. This LED illuminates to indicate that the switch logic circuitry is
overheating. Refer to Section 5 for information about troubleshooting over
temperature conditions.
2.1.3
Fan Fail LED (Yellow)
The Fan Fail LED indicates operational status of the fan. This LED illuminates if
the speed of the fan falls below the normal range. If t he Fa n Fail LED illuminates,
isolate the switch from the fabric, unplug the switch from the AC power source,
and contact your authorized maintenance provider.

Heartbeat LED (Yellow)
The Heartbeat LED indicates the status of the int ernal switch processor and the
results of the Power On Self Test (POST). Following a normal power-up, the
Heartbeat LED blinks about once per second to indicate that the switch passed
the POST and that the int ernal swi tch pr ocess or is r unning. In force PROM mode,
the Heartbeat LED illuminates continuously. Refer to ”Heartbeat LED Blink
Patterns” on page 5-1 for more information about Heartbeat LED blink patterns.

Input Power LED (Green)
The Input Power LED indicates the volt age st atus at the switch logi c circuitr y. This
LED illuminates when the switch logic circuitr y is receiving the proper DC
voltages.

Fibre Channel Ports
Each SANbox2-8c switch has 8 Fibre Channel ports numbered 0–7 as shown in
Figure 2-3. Each of these port s is serve d by a Small For m-Factor Pluggable (SFP)
optical transceiver. The ports self discover the proper mode when connected to
public devices and other switches. You can also configure any port to support a
loop of private devices.
Each port has its own Logged-In LED and Activity LED as shown in Figure 2-3.
The Logged-In LED indicates whether the port and its connected device are
logged into the fabric. The Activity LED indicates the frequency at which frames
are entering or leaving the port.

2.2.1
Small Form-Factor Pluggable (SFP) Transceivers
SFP transceivers plug into the ports; duplex fiber optic cables plug into the
transceivers which then connect to the devices . A port is ca pable of t ransmitting at
1 Gbps or 2 Gbps; however, the transceiver must be capable of 2 Gbps for the
port to deliver at that rate.
The SFP transceivers are hot swappable. This means that you can re mov e or
install an SFP transceiver while the swi tch is operat ing without harming the swit ch
or the transceiver. However, communication wit h the connected device will be
interrupted. Refer to ”Install SFP Transceivers” on page 4-4 for information about
installing and removing SFP transceivers.
2.2.2
Port Modes
All ports are self-configuring generic ports: GL_Ports or G_Ports. A GL_Port
self-discovers in the following ways:
■ FL_Port when connected to a loop of public devices (NL_Port)
2 – General Description
Fibre Channel Ports
■ F_Port when connected to a single public device (N_Port). If the device is a
■ As an E_Port when connected to another FC-SW-2 compliant switch
A G_Port self-discovers as an F_Port when connected to a public device or an
E_Port when connected to another switch. You can also configure a port as a
translated loop port (TL_Port) to support private devices.
2.2.2.1
Fabric Ports
A fabric port supports either a single public device or a loop of up to 126 public
devices. A fabric port c onfigures i t self duri ng the fabric l ogin process as an F_Port
when connected to a single public device (N_Port), or an FL_Port wh en
connected to a loop of public devices (NL_Port).
2.2.2.2
Expansion Port
E_Ports enable you to expand the fabric enabling you to connect SANbox2
switches with other FC-SW-2 compliant swi tches. SANbox2-8c switches
self-discover all inter-switch connections. Refer to ”Multiple Chassis Fabrics” on
page 3-2 for more information about multiple chassis fabrics.

Translated Loop Port
A TL_Port supports a loop of up to 126 private devices with the ability to
communicate with “off-loop” devices such as public fabric devices and private
devices on other TL_Ports . TL_Por t s con nect to de vic es t hat confo rm to the Fibre
Channel-Private Loop SCSI Direct Attach (FC- PLDA) standard. Devices
connected to TL_Ports are registered with the Name Server. Use SANbox
Manager or the CLI to explicitly configure a TL_Port .
A TL_Port acts as a proxy for the off-loop device translating private frames into
and from public frames. Each TL_Port can proxy up to 63 of f-loop public or private
devices that are maintained in its translation entries list.
■ For a TL_Port connected to private target devices, the switch firmware
automatically creates an entry in the translation entries list for each off-loop
initiator device that att empts t o establ ish communic ation. Sof t zoning can be
used to limit the number of potential initiators to 63.
■ For a TL_Port connected to private initiator devices, the switch firmware
automatically creates an entry i n translation entri es list for each tar get device
that is a member of the same soft zone as the TL_Port devices. Before the
TL initiator can communicate with other target devices on your fabric, you
must create a WWN soft zone that includes both the ini ti a tor and targets.
Initiator devices can not communicate with target devices outside the zone.
2.2.3
Logged-In LED
The Logged-in LED indicates the logged-in or initi alization st atus of the connected
devices. After success ful completion of the POST, the switch extinguishes all
Logged-In LEDs. Following a successful loop i nitialization or port log-in, the switch
illuminates the corresponding logged-in LED. This shows that the port is properly
connected and able to communicate with its at tached devices. The Logged-In
LED remains illuminated as long as the port is initial ized or logged-in. An
Logged-In LED will also illuminate when the port has been designated as a donor
port and its buffer credits are being used by another port. Refer to ”Distance” on
page 3-6 for more information about extended credits and donor ports.
If the port connection is broken or an error occurs that disables the port, the
Logged-In LED will flash. Refer to ”Logged-In LED Indications” on page 5-3 for
more information about the Logged-In LED.

2.2.4
Activity LED
The Activity LED indicates that data is passing through the port. Each frame that
enters or leaves the port causes this LED to illuminate for 50 milliseconds. This
makes it possible to observe the transmission of a single frame. When extending
credits, an Activity LED for a donor port will reflect the traffic of the recipient port.
Refer to ”Distance” on page 3-6 for more information about extended credit s and
donor ports.

Ethernet Port
The Ethernet port shown in Figure 2-4 is an RJ-45 connector that provides a
connection to a management workstation. A management workstation can be a
Windows, Solaris, or Linux workstation that is used to configure and manage the
switch fabric. The switch through which the fabric is managed is called the fabric
management switch.
The Ethernet port has two LEDs: the L ink S t atus LED (green) and the Act ivity LED
(yellow). The Link Status LED illuminates continuously when an Ethernet
connection has been establ ished. The Activity LED illumina tes when dat a is being
transmitted or received over the Ethernet connection.

Power Supply and Fan
The power supply converts standard 110 or 230 VAC to DC voltages for the
various switch circuit s. An internal fan provides cooling. Depending on the switch
model, air flow is front-to-back or back-to-front. To energize the switch, plug the
power cord into the switch AC receptacle and into a 110 or 230 VAC power
source.
Note: The power supply and fan are not field replaceable units .
2.6
Switch Management
SANbox Manager is a PC-based Java® application that provi des a g raphical user
interface for fabric management. This application runs on a Windows®, Solari s ®,
or Linux® workstation. The management workstation connects to the fabric
directly through one switch’s Ethernet port and provides in-band management for
all other switches in the fabric. Refer to the SANbox2 Switch Management User’s
Guide for information about SANbox Manager and its use.
2 – General Description
Power Supply and Fan
In addition to SANbox Manager, the switch also supports the following command
line interface tools:
■ Command Line Interface (CLI)
■ File Transfer Protocol (FTP)
■ Simple Network Management Protocol (SNMP)
The CLI provides monitoring and configuration functions by which the
administrator can manage the fabric and its switches. Refer to
Appendix B Command Line Interface for more information about the CLI
commands.
FTP provides a command line interface for loading new firmware.
SNMP provides monitoring and trap functions for the fabri c. SANbox2 firmware
supports SNMP version 1, 2, and 3, the Fibre Alliance Management Information
Base (FA-MIB) version 3.0, and the Fabric Element Management Information
Base (FE-MIB) RFC 2837. Traps are formatted using SNMP version 2.

Planning
Consider the following when planning a fabric:
■ Devices
■ Multiple chassis fa bric s
■ Performance
■ Device access
■ Fabric management
■ Fabric security
When planning a fabric, consider the number of devices and the anticipated
demand. This will determine the number of ports that are needed and in turn the
number of switches. Consider how many and what types of switches are needed.
Consider the distribution of public and private devices as well as targets and
initiators. Public devices have fu ll Fibre Channel addressing capability, and
therefore can communicate with any other public device on the fabric. A G_Port
supports a single p ublic device. A GL_Port can suppor t up to 126 publ ic devices i n
an arbitrated loop.
Private devices do not have full Fibre Channel addressing capability, only the
Arbitrated Loop Physical Address (ALPA) portion. A TL_Port provides a proxy for
a loop of private initiator or target devices allowing communication with off-loo p
public and private devices. Consider the number of private devices in the fabric
and the number of off-loop devices with which the private devices must
communicate. A TL_Port can support up to 126 private devi ces and can maintain
communications with up to 63 off-loop devi ces.
The Fibre Channel ports use SFP optical transceiver s, but the device host bus
adapters you are using may not. Consider whether the device adapters use SFP
transceivers or Gigabit Interface Converters (GBIC), and choose fiber optic cable
accordingly. Use LC-type cable connectors for SFP transceivers and SC-type
cable connectors for GBICs.

Multiple Chassis Fabrics
3.2
Multiple Chassis Fabrics
By connecting switches together you c an expand t he number of availabl e ports for
devices. Each switch in the fabric is identi fied by a unique domain ID, and the
fabric will automatically resolve domain ID conflicts. Because the ports are
self-configuring, you can connect SANbox2 and other FC-SW-2 compliant
switches together in a wide variety of topologies.
3.2.1
Domain ID, Principal Priority , and Domain ID Lock
The following switch configuration settings affect multiple chassis fabrics:
■ Domain ID
■ Principal priority
■ Domain ID lock
The domain ID is a unique number from 1–239 that identifies each switch in a
fabric. The principal priority is a number (1–255) that determines the principal
switch which manages domain ID assignments for the fabric. The switch with the
highest principal pr io rity (1 i s high , 255 is l ow) beco mes the princ ipal switch. If the
principal priority is the same for all switches in a fabric, the switch with the lowest
WWN becomes the principal switch. The domain ID lock al lows (FALSE) or
prevents (TRUE) the reassignment of the domain ID on that switch. Switches
come from the factory with the domain ID set to 1, the domain ID lock set to
FALSE, and the principal priority set to 254. Refer to the SANbox2 Switch
Management User’s Guide for information about changing the domain ID using
SANbox Manager. Refer to the ”Set Config Command” on page B-24 for
information about changing the default domai n ID domain ID lock, and principal
priority settings.
If you connect a set of SANbox2 switches then power them up together, the
principal switch will reassign any domain ID conflicts and establish the fabric. For
any switch with a domain ID c onflict and a domain ID lock set to TRUE, that swi tch
will isolate as a separate fabric.
An unresolved domain ID conflict means that the switch with the higher WWN will
isolate as a separat e fabric , and t he Logged-In LEDs on both switches will flas h to
show the affected ports. If you connect a new switch with its domain ID unlocked
(domain ID lock = FALSE) to an existing fabric and a domain ID conflict occurs,
the new switch will isolate as a separate fabric. However, you can remedy this by
resetting the new switch or taking it offline then back online. The principal switch
will reassign the domain ID and the switch will join the fabric.
3-2 59042-00 A
Note: Domain ID reassignment is not reflected in zoning that is defined by
domain ID/port number pair or Fibre Channel address. You must
reconfigure zones that are affected by domain ID reassignment. To
prevent zoning definitions from becoming invalid, use the Set Config
Switch command to lock the domain IDs. Refer to the ”Set Config
Command” on page B-24.
3.2.2
Common Topologies
This section describes three commonly used topologies:
■ Cascade
■ Mesh
■ Multistage
3.2.2.1
Cascade To pology
A cascade topology describes a fabric in which the switches are connected in a
line. If you connect the last switch back to the first switch, you create a
cascade-with-a-loop topology as shown in Figure 3-1. The loop reduces latency
because any switch can route traffic in the shortest direction to any switch in the
loop. The loop also provides failover should a switch fail.
3 – Planning
Multiple Chassis Fabrics
The cascade fabric shown in Figure 3-1 has the following characteristics:
■ Each chassis link contributes up to 200 MB/s of bandwid th between chassi s,
400 MB/s in full duplex. However, because of the sequential structure, that
bandwidth will be shared by traffic between devices on other chassis.
■ Latency between any two ports is no more than three chassis hops.
■ 24 Fibre Channel ports are available for devices.

3.2.2.2
Mesh Topology
A mesh topology describes a fabric in which each chassis has at least one port
directly connected to each other chassis in the fabric. The example mesh fabric
shown in Figure 3-2 has the following characteristics:
■ Each link contributes up to 200 MB/s of bandwidth between swi tches, 400
MB/s in full duplex. Because of multiple parallel paths, there is less
competition for this bandwidth than with a cascade or a multistage topology.
■ Latency between any two device ports is no more than two chassis hops.
■ 20 Fibre Channel ports are available for devices
