Connecting an existing Et hernet 10/100Ba seT LAN to the switch vi a the fr ont pan el RJ­45 connector gives access to the switch’s internal SNMP agent and also allows remote
Telnet and Web access for remote monitoring and testing.

NOTE: The connection is only for Telnet, SNMP agent and the Web-

based Server access. No Fabric connection is used via this connection.

Verifying Power-On Self-Test (POST)

The following table lists the diagnostic tests automatically run during POST.

Table 2-3 POST Tests

TEST BRIEF DESCRIPTION

Memory Test Checks CPU RAM memory.
Port Register Test Checks the ASIC registers & SRAMs.
Central Memory Test Checks the motherboard SRAMs.
Port Loopback Test Checks all of the switch’s hardware:

POST behaves differently depending on the boot method. A power cycle (power off &
power on) is consid ered a cold boot. All other boots fro m a powered-on stat e (per reboot,
panic, etc.) are considered warm boots.

POST execution per cold boot executes the long version of Memory Test. POST
execution per warm boot executes a shorter version of Memory Test. Boot time with
POST varies depending on the boot method.

frames transmitted, are looped back, and received

As the POST successfully perf orms each of the t ests, a message, “

Passed,” is displayed

via the Telne t.
After the switch compl et es the POST, the por t module returns to a st eady state from the

flashing states shown during the tests.
If a yellow port mod ule light is d isplayed or i s slowly flash ing, this ind icates that t he port

is in a failed state and diagnostic output should be examined to determine the source of
failure.[ See Table 3-2 for other light indications.]

If error conditions are encountered, they can be displayed via Telnet after the switch
completes the POST.

Chapter 3 Diagnostics

Diagnostic Overview

The switch is designed for maintenance free op eration. When the re is a suspected fai lure,
the switch has self diagnostic capabilities to aid in isolating any equipment or Fabric
failures.

The switch supports Power-On Self-Tests (POSTs) and diagnostic tests. The diagnostic

tests determine the switch’s status and isolates problems and are run via telnet
commands. For more information on diagnostic testing commands and procedures, see
the Fabric Operating System Version 2.0 Manual.

Verifying Power-On Self-Test (POST)

When powering on a switch, the switch conducts a series of diagnostic tests including:

■ Dynamic RAM Test

■ Port Register Test

■ Central Memory Test

■ CMI Connector Test

■ CAM Test

■ Port Loop Back Test

Should the switch f ail to complete POST succe ssf ul ly, the green power LED wi ll be set
to blink. This is an indication of a fault in one of the initial stages of POST and indicates
that the CPU is not able to bring up the operating environment. Should this condition
occur, the switch should be returned for repair.

If a serial link is connected to the SilkWorm 2400 switch on initial power up, the switch
type will be printed t o the terminal scree n, followed by the mess age ‘Starting RAM te st’.
On completion of the RAM test, the OS is loaded into CPU memory and the operating
environment is then booted. (A RAM test failure will result in the power LED to blink).

If the switch c an compl etel y boot th e oper ating sy stem, bu t o ther error s are en counte red
during POST, these errors will be logged in the system error log. A Telnet session or
serial link connec ti on t o the switch will enabl e vi ewing of the error log. [S ee t he Fabric
OS Reference Manual diagnosti c and telne t commands for a descr iptio n of the errSh ow
command and details on running diagnostics.]

Removing Power

NOTE: Error messages are stored in RAM and are lost when power is

removed from th e sw itc h. A c cess th e e rror m essa g e l og to vi ew a nd

every 2 seconds.

Each switch port includes an LED indicator. A port with no GBIC installed that if
functioning properly will have no light showing on the LED. If a problem has been
detected with the port, the LED i ndicators above wi ll provide so me indication o f the type
of problem. Faults and problems are depicted with a yellow port indicator.

When a GBIC is installed and a cable is connected to a properly functioning Fibre
Channel device, the LED indica tor will be steady green. If a slow green fla sh is observed
it indicates t he port is seeing light but cannot make a proper fab ric connection. Thi s could
indicate a loopback cable is installed, the fabric is segmented (a E port connection to
another switch cannot be completed and the switches cannot form a fabric), or the
SilkWorm h as been connected to an incompatible switch.

When frame traffic is being transferred on a port, the LED flickers fast green showing
the port is active and transferring data.

Initialization Steps Summary

At power-on or reset, the following steps are executed:

1 Preliminary POST diagnostics
2 VxWorks operating s ystem initia lization
3 Hardware initiali zation (resets, internal addresses assigned to ASICs, serial po rt

initialized, front panel initialized)

4 Full POST
5 Universal Port configuration.
6 Link initialization; receiver/transmitter negotiation to bring connected ports online
7 Fabric analysis; the switch checks for ports connected to other Fabric elements. If

there are other Fabric elements connected, it identifies the master switch.

8 Address assignment; after the master switch is identified, port addresses may be

assigned. Each switch tries to keep the same addresses that were previously used.

These are stored in the switch’s configuration flash PROM.

9 Routing table constru ction; af ter addresses are assigne d, the unicast routing tabl es are

constructed.

10 Enable normal port operation.
