Release Notes for the Cisco 1503
Micro Hub for Software Release 2.01
December 17, 1998
This document describes software release 2.01 for the Cisco 1503 Micro Hub. The Micro Hub 1503
is a small desktop, 8-port hub to connect network devices in a home or branch office. You can
monitor and manage the hub through the console port on the rear panel or by using Telnet. You can
configure the hub with its own firmware or remotely, using optional network management software
(such as CiscoView StackMaker).

Updating to a New Release
This section describes how to upgrade the software on your Cisco Micro Hub.
Caution Updating your Micro Hub software to a software release earlier than release 2.01 (for
example upgrading from release 1.09 to release 1.15) will erase your existing configuration.
You can upgrade your hub software in one of these ways:
•
Download the software from a Trivial File Transfer Protocol (TFTP) server on the same network
as the Micro Hub. Follow the instructions for the tftp-download command in the chapter “Using
Your Hub Software” in the Cisco Micro Hub User Guide.
or
•
Download the software from a terminal or PC that is connected to the hub console port. Follow
the instructions for the start xmodem-download command in the chapter “Using Your Hub
Software” in the Cisco Micro Hub User Guide.
2 Release Notes for the Cisco 1503 Micro Hub for Software Release 2.01
New Software Features
New Software Features
This section describes the new features in release 2.01.
Console-Port Flow Control
The console port now uses flow control.
Caveats
This section describes open and resolved caveats for release 2.01 and release 1.15.
Open Caveats—Release 2.01
This section describes known problems for software release 2.01.
Destination Unreachable Messages
The Internet Control Message Protocol (ICMP) message “Destination Unreachable” and the MIB
object icmpOutDestUnreachs are not implemented in this software release.
Source Quench Message
The ICMP message “Source quench” is not implemented in this software release.
Resolved Caveats—Release 2.01
This section describes problems in release 1.15 that have been resolved in release 2.01.
Show Port Information Command Output
The show port information command now correctly reports link status as “connected” only when
the link is connected. Following is example output of the show port information command:

Resolved Caveats—Release 1.15
This section describes problems in release 1.09 that have been resolved in release 1.15.
IP Addressing
The IP address assigned to the hub by using the bootp-get-ip option of the bootup-option command
will be used by the hub, unless it is overwritten by using the ip address command to enter a different
IP address.
Corrupted EEPROM
The electrically erasable programmable ROM (EEPROM) does not become corrupted when
rebooting the hub. EEPROM corruption results in unexpected hub behavior.
Port “Partition” LED Messages
The front-panel LEDs no longer indicate that a port has been partitioned when it has not.
Incoming ARP Processing
Incoming Address Resolution Protocol (ARP) packets are processed correctly.
Documentation Updates
This section contains changes to the Cisco Micro Hub User Guide that came with your hub.
Software Documentation Changes
Table 1 lists the changes to software-related information in the user guide.

3-2
Connection Using Telnet
You do not have to restart the hub after setting or resetting the hub with an IP address. The hub will
dynamically recognize a new or changed IP address.
3-6
Configuring the Hub
The second item in this section should read as follows:
• “IP address for the BOOTP server, if you want to use the BOOTP feature.”
3-6
Configuring the Hub
An additional item should be added to the list of information that you should have available before
configuring the hub:
• “IP address for the TFTP server, if you want to use the TFTP bootup feature.”
3-20
bootup-option
The factory default for the bootup-option command is bootp-get-ip, which configures the hub to
obtain its IP address from the local BOOTP server. The bootup-option configuration is stored in the hub
Flash memory.
3-22
start tftp-download
The status of the firmware download is not displayed on the terminal or PC screen when you enter the
start tftp-download command.
4 Release Notes for the Cisco 1503 Micro Hub for Software Release 2.01
Automatic Thermal Protection
Automatic Thermal Protection
The Cisco Micro Hub automatically shuts off if its internal temperature reaches 185˚F (85˚C). If the
hub shuts off for this reason, you can restart it after the internal temperature has cooled to
122˚F (50˚C) or below.
Note If the hub is shut down for any other reason (for example, by a building power failure or by
manually turning the on/off switch to off) and its internal temperature is above 122˚F, the hub cannot
be restarted until its internal temperature has cooled to 122˚F or below.
The time required for the hub to cool to 50˚C or below can vary, depending on the ambient
temperature, the number of hubs in the stack, and the position of a particular hub in the stack. The
higher that a particular hub is located in a stack, the longer that hub will take to cool to 50˚C. The
cooling process can take from 5 to 45 minutes.
Password Recovery
Use the procedure in this section if you forget the password used to access the hub
administrator-level commands or if you forget the password required for Telnet sessions. This
procedure should replace the one that begins on page 3-5 in the “Using the Hub Software” chapter
of the user guide.
Step 1
Turn the hub OFF, and wait 60 seconds before going to Step 2.
Step 2
Turn the hub ON.
Wait while the following messages are displayed on the terminal:
Starting the system...
Boot option : boots get ip
Enter BOOTP phase, wait or press Ctrl-C to break...
.....
Bootup Error: Timeout, no response from BOOTP server.
Press RETURN to start a new session
Step 3
Press Ctrl-C.
Step 4
When the following prompt appears, enter a new administrator password:
New administrator password: <new_password>
Step 5
When the following prompt appears, re-enter the new password:
Confirm administrator password: <new_password>
Step 6
Perform the same steps when prompted to enter and confirm a new Telnet session
password:
New telnet-session password: <new_telnet_password>
Confirm telnet-session password: <new_telnet_password>
The following message appears, confirming that the hub is configured with the new
passwords:
Administrator and telnet passwords are modified.

Hub ID Numbers
This section describes the rules that determine the ID number of a particular hub in a stack of hubs.
The hub ID number is used to identify individual hubs in a stack of hubs.
You cannot manually assign an ID number to stacked hub. The ID number is assigned based on how
the hubs are cabled together, not on the particular physical location in the stack itself.
1 The lowest hub ID number in a stack (1) is always assigned to the hub with another hub
connected to its OUT port and with no device connected to its IN port.
2 The highest hub ID number in a stack (any number from 2 to 5) is always assigned to the hub
with no device connected to its OUT port and with another hub connected to its IN port.
Figure 1 illustrates these rules.

Wall-Mounting the Hub
The Cisco Micro Hub can be wall-mounted using two number 6, 3/4-inch screws and the molded
mounting brackets on the bottom of the hub. You must provide the screws. We recommend using
pan-head or round-head screws.

To mount the hub on a wall or other surface:
Step 1
Install the two screws 3.75 inches (9.52 centimeters) apart (horizontally) on a wall or
other vertical surface.
The screws should protrude 0.25 inches (0.64 centimeters) from the surface of the wall.
Step 2
Hang the hub on the screws with either the left side or right side mounting brackets so
that:
•
The LEDs are visible to the user—The LEDs indicate the hub operating status, so the
LEDs should be easily visible.
•
The power supply does not hang from its cable—If the power supply is not supported,
it will disconnect from the cable that connects it to the hub.
Caution If you install the screws in drywall, use hollow wall anchors (1/8 inch by 5/16 inch) to
secure the screws. If the screws are not properly anchored, the strain of the cables connected to the
hub rear panel connectors could pull the hub from the wall.
