Vertical Horizon

VH-2402S and VH-2402S2

Firmware Version 2.06.06.00

April 30, 2004

INTRODUCTION:

It is recommended that one thoroughly review this release note prior to the installation or upgrade of this product.

This release provides support for the Vertical Horizon 24-port 10/100 Ethernet switch, VH-2402S as well as the
new replacement unit, VH-2402S2. The VH-2402S/VH-2402S2 is a 24-port dual-speed standalone, stackable or
rack-mountable switch. The switch provides 24 10Base-T/100Base-TX ports, plus two rear-panel slots for optional
slide-in 100Base-FX, 1000Base-SX or 1000Base-LX modules. One of these slots can also be used for an optional
stacking module that allows you to attach up to seven switches to a 4 Gbps high-speed backplane. There is also
another rear-panel slot that accepts an optional SNMP-based Management Module. This module supports both
in-band and out-of-band access for managing the switch and the attached stack.

The VH-2402S/VH-2402S2 switches can be used in a standalone configuration, or can be stacked up to seven
high to form a single logical switch with up to 168, 10/100 Mbps ports. One optional Management Module is
required for configuring a standalone switch or an entire stack. The optional stacking Interconnect Module and
Interconnect Cables are not included with the base unit and need to be ordered separately.
Management of the switch or stack is provided when an optional Management Module is installed. Management
access is provided in-band via Telnet, SNMP, or out of band, via the serial console port interface either directly or
through an attached modem. An embedded Web agent also provides management capability to any computer on
the network via common HTTP browsers such as Netscape Navigator or Microsoft’s Internet Explorer (both
browsers should be Version 4.0 or above).

Local Console Management (LCM) allows the user to monitor and configure the VH-2402S/VH-2402S2 from a
VT-type terminal. LCM can be used to configure features such as SNMP community names and access rights,
Port Enable/Disable, firmware downloads, and Device IP address as well as most other parameters. LCM can
also provide statistical and diagnostic information about the entire device or an individual port.

Management of the switch or stack is password protected; the same password is used for LCM and for the Web
browser interface. Prior to accessing the Management Module via a network connection, a valid IP address,
subnet mask, and in some cases a default gateway must be configured using an out of band connection or the
BootP protocol. The management option provides SNMP, RMON (4 groups: 1,2,3,9), and Web management for
system control and statistical monitoring.

FIRMWARE CHANGES AND ENHANCEMENTS:

The following known issues have been fixed in this release of firmware:

A condition where an HTTP packet with a source IP address the same as the switch IP address would cause
the switch to stop responding.
A condition where a negative length HTTP packet would cause the switch to stop responding.
A condition where a high rate of HTTP frames would cause SNMP failure to the switch.
A condition where a “negotiate authorization frame” would cause the switch to stop responding.
