VORSICHT  
Some fiber optic equipment can emit laser or infrared  
light that can injure your eyes. Never look into an optical  
fiber or connector port. Always assume the cable is  
connected to a light source.  
Bestimmte Lichtleitergeräte können für die Augen  
gefährliches Laser- oder Infrarotlicht abstrahlen.  
Vermeiden Sie es daher unter allen Umständen, direkt in

schauen. Gehen Sie immer davon aus, daß  
Lichtleiterkabel mit einer Lichtquelle verbunden sind.  
DANGER  
AV ISO  
Certains équipements à fibre optique peuvent émettre un  
rayonnement laser ou infra-rouge pouvant provoquer des  
troubles oculaires. Ne regardez jamais à l'intérieur d'une  
fibre optique ou d'un port de connecteur. Considérez que  
le câble est connecté en permanence à une source  
lumineuse.  
Ciertos equipos de fibras ópticas pueden emitir luz  
lasérica o infrarroja con riesgos de lesiones en los ojos.  
No se debe nunca mirar en una fibra óptica o una puerta  
de conexión. Siempre hay que suponer que el cable está

What is the DIGITAL VNswitch 900GV?  
What is the DIGITAL VNswitch 900GV?  
The DIGITAL VNswitch 900GV (also referred to in this manual as the module) is a  
single Gigabit Ethernet port switch that allows a Modular Media Interface (MMI)  
connection using industry standard GBIC (Gigabit Interface Connector). The Gigabit  
Ethernet port supports: Gigabit Ethernet Single-Mode Fiber (SMF), and Gigabit  
Ethernet Multi-Mode Fiber (MMF).  
The DIGITAL VNswitch 900GV network module is a true backbone network switch  
that supports complete filtering (including source address, destination address,  
protocol type, and VLAN) for greater network control, increased security and  
bandwidth utilization, and reduced propagation of network problems.  
The module includes a large address table (approximately 8,000 entries) and is fully  
IEEE 802.1d standards-compliant, ensuring the high performance and packet integrity  
required in large switched networks. The module’s MMI port is IEEE 802.3z  
standards-compliant.  
When installed into a MultiSwitch 900 chassis and connected to the VNbus, the  
module can function as an uplink for other DIGITAL VNswitch 900 series modules.  
You can install and configure the module in a DIGITAL MultiSwitch 900 chassis. The  
module is fully interoperable with other modules when installed in the DIGITAL  
MultiSwitch 900 chassis.

from the module without detaching the module from the chassis.  
Configuration and Management  
The following configuration and management options are available:  
Auto-configuring at power-up.  
Support for up to 256 internal addresses for management and other purposes.  
Manageable via SNMP and the Command Line Interface (CLI) management via  
Telnet or an attached terminal device.  
Upgradeable device firmware (in nonvolatile flash memory) using TFTP with  
clearVISN Flash Loader.  
A built-in SNMP management agent. It supports a comprehensive graphical user  
interface (GUI) (using the clearVISN MultiChassis Manager) that is identical for  
both in-band and out-of-band management.  
Support for up to approximately 8,000 network addresses.  
User-configured rate limiting for broadcast and multicast packets by address and  
specified protocol.  
Serves as an uplink to Gigabit backbones for Ethernet, Fast Ethernet, FDDI and  
ATM modules installed in a MultiSwitch 900.

Assigning an IP Address  
Assigning an IP Address  
After installing the module in a DIGITAL MultiSwitch 900 chassis and connecting the  
cables, you need to assign an IP address. Do this using the command line interface,  
which is accessed through a terminal connected to the setup port on the MultiSwitch  
900 chassis.  
NOTE  
The VNbus does not connect to the backplane by default. The VNbus is  
configured using the clearVISN MultiChassis Manager.  
To perform a Telnet session, you must assign an IP address. To do this, complete the  
following steps:  
Step

Set the in-band IP address.  
Set the default gateway, if necessary.  
Return to the VNswitch 900GV INSTALLATION MENU and select  
[2] Restart with Current Settings.

Open a Telnet session into the module from the management station for  
further configuration. The system displays copyright statements and the  
following prompt:

[9] Start Redirect Mode  
[9] Start Redirect Mode  
The Start Redirect Modeoption redirects the DIGITAL MultiSwitch 900  
Chassis Manager setup port to the setup port of any network module (such as the  
DIGITAL VNswitch 900GV) that is installed into the MultiSwitch 900. This option  
allows you to configure or obtain status of an installed network module by accessing  
the specified network modules installation menu.  
After you choose the Start Redirect Modeoption from the DIGITAL  
MultiSwitch 900 INSTALLATION MENU, the screen prompts you for a slot  
number, as shown in the following example. After you enter the number of the slot in  
which the DIGITAL VNswitch 900GV is installed, the console is redirected to this  
slot.  
NOTE  
The slot number may change to reflect the slot number in which your module is  
installed.  
The following example shows you how to redirect the console to a specific slot:  
Enter the slot number for redirection (1-8): 3 <Return>  
Console redirected to 3: VNswitch 900GV  
Attempting connection [Ctrl/C to Abort]...  
If the redirection is successful, after you press Return, the VNswitch 900GV  
INSTALLATION MENUappears on your screen. If redirection is not successful, for  
example, you entered a number for an empty slot, you can press Return to start again  
at the DIGITAL MultiSwitch 900 INSTALLATION MENU.

[5] Set Out-of-Band Interface IP Address  
This option prompts you to change or enter the IP address and subnet mask for the out-

SNMP communications when management stations are on the same subnet as the  
module.  
The format for these values is the standard 4-octet dotted decimal notation, where each  
octet of the address is represented as a decimal value, separated by a decimal point (.).  
If the module is in a MultiSwitch 900, the OBM feature allows you to manage your  
module through the OBM port located on the MultiSwitch 900. To enable out-of-band  
management, you need to assign an OBM IP address.

The module's Power LED lights as soon as power is applied to the unit.  
The module initiates its built-in self-test. Flashing Port State LEDs and

The module's LEDs provide dynamic indications of the module’s status. The LEDs can  
be in various states (on, off, or flashing), and can change color (green or yellow)

Problem Solving Using LEDs  
When diagnosing a problem with the module, note that the problem is often indicated  
by the combined states of the module LEDs. Table A-2 lists the typical combined  
states of the LEDs for various error conditions that can occur during initial installation  
of the device, along with probable causes and corrective actions to take.  
NOTE  
If any of the following problems persist after taking corrective action, either  
replace the module or contact your DIGITAL service representative.
