Downloading Image 2
1. You can use FTP to download the second image. Refer to Using FTP to Download the
SMM Images on page 6-35 for using FTP download. After Image 2 is downloaded,
configure it to run and test that the image can be used as a backup for Image 1. All
of the functions and features are the same in both images.
2. After verifying that Image 2 will run, set the SMM back to run Image 1 so there will
not be any confusion over which image is configured to run in the event of an error.
MIBs
ARRIS Developed MIBs
The SMM monitors both enterprise and standard MIB objects for all modules. The ARRIS
developed MIBs are listed in Table A.12, ARRIS Developed MIBs —page A-11. The
chp-MAX5000-TC.MIB must be loaded first and the remaining MIBs can be loaded in any
order.
Common MIB Operation
The chp-MAX5000.MIB allows the SNMP manager to view the overall status of all monitored
chassis and modules. All modules are automatically discovered when plugged into a module
slot in the CHP chassis. Removing a module requires you to physically remove the module
and then send a reset slot command to the SMM. The SMM will then remove the module
from the configuration tables. Any module that is just removed from the slot will report a
module down alarm.
Any chassis that is physically removed from the RS-485 bus will report a chassis down alarm.
In order to remove the chassis from the configuration, the
shelfrem
command must be issued
from the Telnet window. All chassis configuration additions and removals are done via the
password protected Telnet interface on the SMM Controller module. When the chassis is
removed via Telnet it will no longer be managed, even if it is plugged in. Any chassis that is
configured without actually being connected to the RS-485 bus will raise an alarm that the
chassis is down. This aids in configuration of the CHP Site. When a chassis is marked down,
it will continue to be polled at a reduced rate until it is removed from the configuration.
Because of this reduced polling rate, when the chassis is no longer down it could take up to
2 minutes to be recognized, then standard polling of the shelf and modules will begin. If a
chassis is reconnected and added in Telnet, the chassis is automatically discovered within 20
seconds.
Standard MIBs
ARRIS recommends using CORView Element Manager Software to monitor, archive, and analyze
data retrieved from SNMP Agents. This browser supports SCTE's (Society of Cable and
Telecommunications Engineers) HMS standard for the SNMP monitoring and management
of inside and outside HFC cable plants. It also serves as a basic HMS SNMP Manager,
supporting HMS MIBs and decoding of HMS specific, SNMP Traps and Notifications. All of the
required open source MIBs are provided with this browser.
The Standard MIBs are listed in Table A.13, Standard IETF MIBs —page A-14 and Table A.14,
Standard HMS MIBs —page A-14.
