Introduction
IBM offers a family of Fibre Channel switching products that allow
implementation of a storage area network (SAN) topology in Fibre
Channel Protocol (FCP) or fibre connection (FICON) environments.
IBM offers several alternatives to build a robust and scalable SAN
infrastructure that meets the customer’s data center requirements.
This manual provides information and procedures for installing the
SAN Router, and for configuring and managing by the SAN Router
Element Manager and the Enterprise Fabric Connectivity Manager.
The SAN Router Element Manager is a Web-based Java applet which
is used to configure, monitor, and troubleshoot the router.
SANvergence Manager is a Java-based collection of software tools for
managing a multi-protocol storage fabric consisting of McDATA
switches and gateways.
Both applications can be used to configure and manage the SAN
Router. SAN Router Element Manager is used to configure an
individual SAN Router while SANvergence Manager is used to
configure and manage multiple SAN Routers in a SAN environment.
When used with SANvergence, SAN Router Element Manager can be
launched from SANvergence.

SAN Router
The SAN Router (also referred to as router in this manual) supports
iSCSI, iFCP, and R_Port for connecting to both IP backbones and
legacy Fibre Channel (FC) fabrics. The SAN Router connects to a
wide range of Fibre Channel and IP end systems. The SAN Router
supports TCP/IP routing over extended distances at wire speed.
The SAN Router can be deployed for multiple, concurrent
applications, including SAN routing in the data center (mSAN
routing), SAN routing over distance (iSAN routing) for disaster
recovery, and iSCSI access to Fibre Channel storage.
mSAN routing enables you to build very large, stable fabrics where
faults in one part of the network do not impact traffic in other parts.
For disaster recovery, the backup site can be quite distant, thanks to
Fast Write technology, which can sustain wire-speed throughput in
spite of high-link latency. The TCP ports on the SAN Router can
support iSCSI access to Fibre Channel storage.
The SAN Router offers:
• mSAN internetworking for scalable and fault-tolerant SANs.
• Compression for increased bandwidth.
• Support for full fabric and private and public loop FC devices.
• Fast Write™ technology for maximizing throughput across long
distances.
The SAN Router is shown in Figure 1, The SAN Router, front view, and
described in SAN Router physical description. A rear view with power
supply locations is shown in Figure 2, The SAN Router, rear view.

SAN Router physical description
All ports and connectors are located on the front of the SAN Router,
except for the power connectors, as described in the following
paragraphs. The rear of the SAN Router contains only the power
connectors and cooling fans. The Field Replaceable Units (FRUs) are
the optical transceivers, power supplies (which include internal fans),
and base machine.
Power
connections
There are two standard power connections located on the rear of the
SAN Router. Each of these power connections supplies AC power to
a different power supply for power redundancy and backup. Either
power supply can support the SAN Router operation, but it is
recommended that both be connected, each to a different power
source.
NOTE: If one power supply fails, the SAN Router will continue to operate
but the failed power supply should be replaced as soon as possible to retain
redundancy.
Fibre channel
ports
There are twelve user-configurable fibre channel ports located on the
front of the SAN Router, labeled 1 through 12. These port connections
hold SFP transceivers that support FC connectivity at 1 or 2 Gbps or
GE connectivity at 1 Gbps. The ports can be configured as:
• FC_Auto (default)
•FL_Port
• F_Port
• L_Port
• R_Port

Chapter 1: Overview
To the left of each FC port is an LED that indicates the configuration
and status of the associated port. For more information about these
LEDs, see Table 20 on page 52.
Intelligent ports
for IP connection
The SAN Router provides four intelligent ports for Gig Ethernet (GE)
connectivity, labeled 13 through 16. Each intelligent port for IP
connectivity can be configured for either Internet Small Computer
Systems Interface (iSCSI) or Internet Fibre Channel Protocol (iFCP).
Management ports There are two management ports located on the front of the SAN
Router. An RS-232 serial port that can be connected to a VT100
terminal emulator for access to SAN Router console that supports the
Command Line Interface (CLI), and an RJ45 port that can be
connected to the LAN for out-of-band management using the SAN
Router Element Manager or the SANvergence Manager. The RJ45
management port can be accessed by any PC on the LAN with a web
browser or Telnet based CLI.
Operational features
The SAN Router features are described in Table 3, SAN Router
features. Some features are optional and may not be present in some
SAN Router software versions.
Tabl e 3 SAN Router features
Feature Description
Intelligent ports Four intelligent ports, which can be configured for
Internet Small Computer Systems Interface (iSCSI) or
Internet Fibre Channel Protocol (iFCP). An Intelligent
port is also referred as TCP port.
Internet Fibre Channel
Protocol (iFCP)
standards track
protocols
The SAN Router supports the IETF draft standard for
iFCP, which provides connectivity and networking for
existing Fibre Channel devices over a TCP/IP network.
iSCSI The SAN Router supports IETF standard based iSCSI
protocol.A TCP port can be configured for either iSCSI
or iFCP.
SAN16M-R SAN Router Installation And Service Manual

R_Port Support for FC-SW2 standard E_Port as well as
Brocade interoperability mode allows you to fully
integrate the SAN Router into an existing Fibre Channel
SAN that includes one or more Fibre Channel switches.
Fast write The Fast Write software feature available on intelligent
ports improves the performance of write operations
between Fibre Channel initiators and targets in a Wide
Area Network (WAN). The improved speed depends on
the WAN Round Trip Time (RTT), available buffer space
on the target, number of concurrent I/Os supported by
the application and application I/O size.
Router Zoning Using SANvergence Manager, network management
software, or the command line interface (CLI), you can
create zones across networks.
You can use zone sets for periodic reallocation of
network resources. For example, you can have one set
of zones for daytime data transactions and another set of
zones for nighttime backups. You can create zones
across networks.
Real-time and historical
system logs
The Element Manager and LogViewer can be used to
look at current system log messages from the connected
SAN Router.
Compression Compression technology available on intelligent ports
identifies repetitive patterns in a data stream and
represents the same information in a more compact and
efficient manner. By compressing the data stream, more
data can be sent across the network even if slower link
speeds are used.
Jumbo Frames Since the maximum Fibre Channel payload size is 2112
bytes, two regular Ethernet frames are required. The
Jumbo Frame option extends the Ethernet payload to
2112 bytes. With the support of Jumbo Frames, a Fibre
Channel frame can be mapped to just one Ethernet
frame, providing more efficient transport. For iSCSI
traffic, up to 4K size frames are supported.

Task 2: Mounting the SAN Router
Surface mounting the SAN Router
To install the SAN Router on a horizontal surface, or other standalone
environment:
1. Remove the SAN Router from the protective bag.
2. Place the SAN Router in a well-ventilated area to ensure free
airflow to the cooling fans. Airflow enters at the rear
(non-port-side) and exits at the front (port-side) of the chassis.
Cabling should be routed so that ventilation openings are not
obstructed. Ensure that the operating temperature specifications
in Appendix A, Environmental requirements are met at the airflow
entrance of the chassis.
Mounting the SAN Router in an equipment rack
To install the SAN Router in a customer -- supplied equipment rack,
refer to the IBM TotalStorage SAN16M-R Rack-Mount Installation
Instructions. Ensure that the operating temperature specifications in

Multiple power cords
(L003)
The SAN Router is equipped with universal power supplies that
adjust to the 110V - 220V standards used in various countries. Two
120 VAC three-conductor power cords are shipped with the SAN
Router. If you need a different power cord, please contact your IBM
representative.
The SAN Router has no power switch and powers up when
connected to a live power source. Either power supply can maintain
power for the SAN Router, however we recommend connecting both
power supplies, each to a separate power source for redundancy
protection.
To power up the SAN Router:
1. Locate the power connections at the rear of the SAN Router. See
Figure 2, The SAN Router, rear view.
2. Connect the female end of a power cord to the SAN Router and
the male end to a live power outlet.
3. Connect the second power cord to the SAN Router.
NOTE: You should maintain reliable grounding of the rack-mounted
equipment. Pay particular attention to the supply connections other than the
direct connections to the branch current (for example, when using power
strips)

the network before the SAN Router is managed by SANvergence
Manager. If you do not choose to set the 10/100 Management Port IP
Address now (with the CLI) you can do so from the Element
Manager later.
Changes made to the management port IP address will take effect
only after a SAN Router reset (CLI command reset system or Element
Manager File\Reset System).
The management port IP address is not affected by resetting the SAN
Router to defaults. The management port IP address and its
parameters (permanent route) remain the same until you actively
change it using either the CLI or the Element Manager.
Out-of-Band
management
The 10/100 Ethernet Out-of-Band Management port provides for
out-of-band IP-based management. This interface allows simple
network management protocol (SNMP), Telnet, and web-based
management traffic to be separated from storage traffic through use
of a separate LAN. The IP address of the management port must be in
a different subnet than the SAN Router Inband IP address.
Set the management IP address using the CLI:
1. Press the Enter key to display the CLI prompt.
2. Logon to the SAN Router. Type modify at the Access Mode
prompt and private at the Password (community string) prompt.
3. Set or change management port IP address using the CLI:
• At the command prompt enter:
set mgmt portaddr <IP address><subnet mask>
where:
IP address = IP address of the management port
subnet mask = subnet mask of the management port (optional)
4. Set a permanent route to the network management station.
• At the command prompt enter:
set mgmt permroute <addr><mask><gateway>
where:
address = IP address of the network management subnet. This IP
address is used to add a static route to the SAN Router’s route
table. This is required by the management station if its on a
different subnet than the 10/100 interface.
23
Chapter 2: Installing and connecting the SAN Router
mask = subnet mask of the network management subnet.
gateway = IP address of the gateway router. The gateway router
is a directly connected router to which management traffic should
be forwarded.
5. Save the configuration using the CLI:
• At the command prompt enter:
save
6. Reset the system using the CLI:
• At the command prompt enter:
reset system
The management IP address is now set and ready for normal
out-of-band management. If you choose to continue configuring the
SAN Router using CLI, please see the E/OSi Command Line Interface for
IBM TotalStorage User Manual.
Task 7: Initiating the Element Manager
1. Connect the standard RJ45 Cat 5 Ethernet cable from the LAN to
the 10/100 management port (RJ45). See Figure 4 on page 21.
• Wait for the SAN Router to come up (watch for the link LED to
light).
NOTE: The link LED is located next to the RJ45 connector. A steady light
means the port is active and a blinking light means there is traffic.
2. Ping the IP address you entered in Task 6 to verify network
connectivity using the network management host.
• If there is no ping response, contact your network
administrator to set up connectivity between the network
management station and the SAN Router.
You are now ready to configure the SAN Router using the Element
Manager.
Before you connect the SAN Router to the network
You have set the network management IP address to suit your
network environment. The SAN Router is also shipped with a default
SAN16M-R SAN Router Installation And Service Manual
24
SAN Router IP address and a subnet mask which are configured at
the factory. It is recommended that these default parameters also be
changed to fit your network environment, all ports be configured to
suit your network, and all IP addresses are valid and unique before
connecting cables. See the Administration and Configuration Manual for
more information.
Task 8: Connecting Intelligent/TCP ports
The GE SAN or intelligent ports are labeled 13, 14, 15, and 16 on the
front of the SAN Router as shown in Figure 5, Intelligent ports. The
default settings depend upon which configuration was purchased.
• Connect the iFCP port to MAN/WAN network (next hop IP
router or SAN Router).
• Connect the iSCSI port to the iSCSI initiator or dedicated iSCSI
LAN network.
NOTE: Ensure that you have the IP addressing information available so these
ports can be correctly configured for the connected network.
Figure 5 Intelligent ports
Task 9: Connecting fibre channel ports
Fibre Channel port connections
The ports are labeled 1 through 12 on the front of the SAN Router (see
Figure 6, Fibre channel ports (two of twelve). The default setting is FC -
Auto. The FC port LEDs, located to the left of the associated ports, are
dual-color LEDs (green and amber). Green indicates a GE setting for
the port, and amber indicates an FC setting for the port. The LEDs
blink when there is traffic, the rate of blinking increasing with more
traffic.

Cable guidelines
ATTENTION! Review and implement the following cable guidelines to
avoid signal interference or cable damage.
• Use RJ45 cable for the Network Management port.
• Use DB9 null modem cable for the console port.
• Confirm you have appropriate cables to attach the devices, for
example the server and targets.
• Do not bend fiber optic cables to a radius smaller than three (3)
inches. Doing so could result in serious degradation in
performance or complete loss of connectivity.
• Do not lay copper cables near transformers or alongside power
cables for any distance. Doing so could introduce noise into the
signaling.
• Avoid laying cables near sharp edges or where objects or other
equipment can crush them.
• Laser types at each end of any link must match.

CAUTION
Data processing environments can contain equipment transmitting
on system links with laser modules that operate at greater than
Class 1 power levels. For this reason, never look into the end of an
optical fiber cable or open receptacle.
(C027)
SFP transceivers are usually shipped with protective rubber plugs
installed. If you do not plan to immediately connect fiber cable to the
SFP after installation, leave the protective plugs installed.
To connect an SFP device, follow these steps:
1. Insert the SFP through the port cover into the connector until the
connector is firmly connected to the SFP. You should hear an
audible click as it snaps into place.
2. Remove the protective plugs.
3. Install the fiber cabling.

Upgrading firmware (E/OSi)
This section provides information on how to upgrade firmware on
the SAN Router. This details the constraints and limitations involved
in upgrading firmware, tips for migrating to 5.0 version, and steps to
follow for downloading and activating the firmware or restoring a
previous firmware version for the SAN Router.
NOTE: You may also need to upgrade the bootrom file if you have another
version installed. Refer to Upgrading bootrom (E/OSi) on page 46 to determine
if you need to upgrade and to view the upgrade instructions.

Requirements for upgrading firmware (4.6/4.7 to 5.0)
NOTE: Migrating from EOSi version 4.6/4.7 to 5.0 involves certain
requirements that must be fulfilled before upgrading your firmware to 5.0
version.
The E/OSi 5.0 firmware size is larger than E/OSi 4.6 or 4.7 firmware
size and so, a second flash bank is required to enable the SAN router
to store two E/OSi firmware images such as a previous firmware
version and a newer firmware version. Due to this, there are some
constraints when the combination of E/OSi 4.6 or 4.7 or 5.0 are used.
• Bootrom should be upgraded to version 1.0.5 (For procedure,
refer Upgrading bootrom (E/OSi) on page 46).
• Primary partition (location #1) is recommended only for storing
images with E/OSi 5.0 version. You must migrate to E/OSi 5.0
from active secondary partition (location 2).
• Secondary partition (location 2) image can contain a previous
version such as E/OSi 4.6/4.7/5.0 but should be upgraded from
E/OSi 5.0 from primary partition (location 1). To achieve this,
download E/OSi 5.0 to primary partition (location 1), then
download to the secondary partition image (location 2).
• After migrating to E/OSi 5.0, if the secondary partition (location
2) contains either E/OSi 4.6/4.7 images and is active then the
firmware upgrade page in E/OSi 4.6/4.7 Element Manager will
be empty for the secondary partition (location 2). However this
will not have any impact in the functionality of the firmware.
Checklist for migrating to 5.0 version
To migrate to 5.0 version without any requirements, ensure that you
satisfy all these checklist items:
1. Read constraints and limitations before upgrading the firmware.
2. Choose the E/OSi firmware version you want to keep on the
secondary partition (location 2).
3. Upgrade the bootrom to v1.0.5.
4. Activate the secondary partition (location 2) and reboot the SAN
Router.
5. Upgrade the primary partition (location 1) with the E/OSi 5.0
firmware version.
43
Chapter 3: Maintenance and troubleshooting
6. Activate the primary partition (location 1) and reboot the SAN
Router.
7. Upgrade the secondary partition (location 2) with the desired
image.
Downloading firmware
ATTENTION! Please ensure that you have gone through the Requirements
for upgrading firmware (4.6/4.7 to 5.0) and Checklist for migrating to 5.0
version before you start downloading the firmware to avoid any irreversible
change to the SAN Router settings.
The SAN Router can store up to two versions of firmware – the

SAN Router physical connections
All ports and connectors are located on the front of the SAN Router,
as described in the following paragraphs. The rear of the SAN Router
contains only cooling fans, which are not accessible. The Field
Replaceable Units (FRUs) are the Fibre Channel Port transceivers and
power supplies which include fans.
Power
connections
There are two standard power connections located on the rear of the
SAN Router, one at each end. Each of these power connections
supplies AC power to a different power supply for power
redundancy and backup. Either power supply can support the SAN
Router operation, but it is recommended that both be connected, each
to a different power source to maintain redundancy.
NOTE: If a power supply is not connected, an error message will be
generated.
The two power supplies, located on the rear of the SAN Router are
FRUs (see Figure 14). To remove a power supply, review Chapter 5,

Problem Meaning and solution
A yellow border appears around one of
the ports on the Element Manager device
view.
This usually indicates that the port is not properly configured or the port has been
disabled.
• The GE ports may display yellow if you initially configured the SAN Router without
IP address entries for these ports. You must configure one or the other with an IP
address, using CLI or Element Manager.
• In Element Manager, make sure that you have appropriate IP address entries for
the Management IP Address and the GE port(s).
• If you made any changes or additions to the IP configuration, choose Save
Configuration from the File menu, then also choose Reset System from the File
menu.
• Be sure to save any open applications and quit any operations currently running on
the SAN Router prior to rebooting.

manager port IP address below 224.x.x.x to solve the problem.
You see the following error message:
WARNING: IP ADDRESS IS 0, PLEASE
SET IP ADDRESS AND RESET
The SAN Router does not yet have a valid inband IP address. Use the Inband Address
Configuration dialog box (Configuration >System >Inband Address) to set the inband
address.
You are not able to download firmware
using Element Manager.
• A TFTP server must be running on a server that the SAN Router can connect to
through either the management port or a GE port. The TFTP protocol is not FTP.
• File names and paths are critical. Try to move the firmware to the same directory
on the servers where the TFTP server is located and use the name of the file with
the new path in the dialog box. The path that you enter in Element Manager is
always relative to the TFTP server's root directory.
• Try pinging the IP address of the management port for out-of-band management or
the SAN Router Inband IP address for inband management from the TFTP server
(example: ping 192.168.2.170).
After setting up your iFCP configuration,
you can’t see your remote devices.
• Check both iFCP ports and make sure you have link lights between the port and
the SAN Router/GE switch on either side. Ping across the link from local to the
remote SAN Router.
• Check in the Element Manager to make sure that each SAN Router has a unique
mSAN ID (Configuration>iFCP>Setup) and that the SAN Router has been reset
since this was changed.
• Check in the Element Manager to make sure that the iFCP port IP addresses are
on the same subnet or that the next hop router address is the correct next
hop/gateway.
• Check in the Element Manager to make sure that the Zone IDs are the same for the
mutually exported zones (Configuration>iFCP>Remote Connections).
• Check in the Element Manager to make sure that the remote SAN Router status is
up by going to: Configuration>iFCP>Remote Connections and checking the Status
column for the SAN Router in question. It should say “Up.”

Chapter 3: Maintenance and troubleshooting
The operating system is not seeing my
attached storage devices.
• Normally there is a problem with the connection, the interface, the zoning, port type
or the drivers when the devices are not being recognized.
Check the front panel of the SAN Router or use Element Manager to make sure
the port type is set correctly for each port. Refer to the SAN Router’s
Administration and Configuration Manual for more details.
Ensure that the transmit and receive optical lines are not reversed such that the
transmitters are connected to each other.
If you have SANvergence Manager. Select one of the SAN Routers in the
SANvergence Manager window and select mSAN Configuration to display the
mSAN Configuration window. Make sure the proper devices are listed and that
they are in a common zone. If you need to make zone configuration changes,
be sure to commit the changes and save them to flash memory in the SAN
Router.
Verify that the cables being used are intact and of good quality.
You aren’t sure which Fibre Channel port
type to assign.
Fibre Channel port parameters that you can configure through the FC/Ethernet Port
Configuration dialog box in the Element Manager include:
• FC Auto - Ports that automatically sense whether the type of connection is F_Port
or FL_Port. Use FC-Auto for connecting Fibre Channel devices such as host bus
adapters and storage targets. This will negotiate either arbitrated loop or
point-to-point connections with the connected devices.
• F_Port - A port to which non-loop N_Ports are attached.
• FL_Port - A port to which one or more NL_Ports in an arbitrated loop are attached.
• L_Port - Private loop or filer mode. In this mode, the port will come up in loop mode
without requesting devices to do FLOGI; in other words, the connecting device is
forced to be a private device. Most NAS filers need the port to be configured in this
mode.
• R_Port - a fabric extension port used to establish inter-switch links (ISLs) between
a SAN Routers and FC switches. R_Ports allows you to interconnect, zone, and
manage existing fabrics with mSANs. R_Port is an added-cost option; it is not
available in the basic SAN Router software package. Use R_port to establish
inter-switch links (ISLs) between FC switches and Eclipse SAN Routers. R-Port
allows you to interconnect, zone and manage existing fabrics with mSANs.
You don’t know whether to set your Fibre
Channel devices to Arbitrated Loop or
Point-to-Point.
The SAN Router will support either arbitrated loop or point-to-point. Certain host bus
adapter drivers or firmware have preferred modes in which they will try to negotiate
one topology and revert to the other if that is not available. This is an unreliable method
therefore we recommend you set your devices to point-to-point or arbitrated loop only
mode.

GE port troubleshooting
Table 22 GE port problems and solutions
Problem Solution
Only one of your GE ports is showing
activity.
• Check that the GE cable is securely inserted in both the SAN Router and the
Gigabit Ethernet port on the SAN Router
• Make sure that the Gigabit Ethernet cable is not damaged and that nothing sharp
or heavy has been placed directly on it (this may damage the delicate fiber of the
cable).
• Check that the RX and TX connectors are correct on the cable (the individual
connectors may need to be switched around to correct the signal).
• Try another cable.
• Make sure that the cable doesn't have any kinks in it and that it is not damaged.
You need to know how to use In-Band
management.
You can manage the SAN Router through the Gigabit Ethernet interface. The IP
address to use in SANVergence Manager is the SAN Router’s in-band IP address.
In-band management is only supported on a Gigabit Ethernet port set to Gigabit
Ethernet port, not Gigabit Ethernet trunk port or COS ports.
Ethernet frames are being dropped. • A GE switch with mFCP links between the SAN Router in the same cluster
must
have IEEE 802.3x symmetric flow control enabled to both send and receive pause
frames. Refer to the documentation for your GE switch vendor for further
information. GE SAN Routers in an iFCP or iSCIL link do not require 802.3x flow
control.
• Check to ensure you have GE rated SFPs. Fibre Channel rated SFPs will not
function properly with GE.
• Physical problems such as dirty optical connections, damaged cables or sheaths or
damaged SFPs will cause intermittent communication errors.
• Consider rate limiting.
You need to know which GE port type to
select on the SAN Router.
The GE port is the most basic port type. If you are going to use in-band management,
at least one port on the SAN Router must be set to this mode. GE trunk ports use a
trunking protocol to aggregate two or more links to a supported GE switch. COS mode
enables a class of service function that is supported by some products.

Serial Management Console troubleshooting
Review Table 23, Serial Management Console troubleshooting to help
troubleshoot problems with the console connected to the
management port.
Retrieving the system log
The System Log (different from the Element Manager Message Log)
contains errors or warning states encountered at the SAN Router.
This could include ports going up and down, mSNS unable to zone, a
SAN Router task failing, and so on.
The System Log is a fixed size. New entries are written to the
beginning of the log overwriting the oldest entries. The log may be
cleared out from time to time, so it is important to remember that the
log may not include every error.
Tabl e 23 Serial Management Console troubleshooting
Problem Solution
The Serial Management Console will not
come up.
There are several reasons that you may not be able to bring up a console connected to
the serial port. Make sure the “null modem” cable on the management workstation is
plugged in securely to the proper serial port.
Check that the settings for the VT100 terminal emulator are correct. The default
settings are:
• Baud Rate: 9600
•Data Bits: 8
• Parity: None
• Stop Bits: 1
• Flow Control: None
Make sure that you have selected the proper COM port for the emulator and that the
Serial port is enabled in the system BIOS (check with your computer manufacturer for
more information on this).
The characters on the Serial
Management Console screen are
garbled.
This is typically caused by a configuration problem with the VT100 emulator terminal:
Go to the advanced settings for the terminal and make sure that the VT100 terminal
emulation setting is set to ANSI or auto detect.
There are strange messages on my
screen.
There are different occasions during loading sequences or operation where messages
may appear, but if they continue to appear for no apparent reason, or if you have
further questions, contact Customer Support for further assistance.

To upload the System Log from the SAN Router to the management
workstation, follow these instructions:
1. Select File>System Log>Retrieve to display the Retrieve System Log
dialog box (Figure 15 on page 58).
Figure 15 Retrieve the system log dialog box
2. Type the IP address where the management workstation TFTP
server resides.
3. Type or modify the name of the file where you want this segment
of the log stored. For some TFTP servers, if you are creating a new
file, you must place it in an existing subdirectory.
4. Click the Retrieve button.
5. Click OK to empty the System Log.
Accessing SNMP alerts or alarms
The SAN Router sends SNMP traps (alerts or alarms) to designated
IP addresses (workstations) where the alerts or alarms can be viewed.
In order to receive SNMP alerts, the SAN Router must be configured
to enable SNMP traps (alerts or alarms). Review the Administration
and Configuration Manual for information on configuring SNMP traps.
The SNMP traps are configured to be routed to specific workstations
based on IP address. The data from the SNMP alerts can be viewed
from Element Manager and SANvergence Manager. Also, there is a
utility called the TrapViewer that is shipped with SANvergence
Manager you can use to view the SNMP alerts or alarms.

Performing a loopback test
If you suspect there is a hardware problem with a port, you can insert
the loopback connector, which is supplied with the router, into the
port to determine if the port is operating correctly. If the LED turns
solid when the loopback connector is plugged into the port, then the
port hardware is operating correctly. If the LED does not turn solid,
then review the Administration and Configuration Manual for
additional troubleshooting procedures.
NOTE: The loopback connector works only with Ethernet ports; not FC
ports. In order to test a port, you would need to change the port from FC to
Ethernet, then test the port. If you do this, the router will need to be reset for
changes to take effect. After you complete the test, you will need to
reconfigure the FC ports.
