Importance of Routine Maintenance
□Routine maintenance is a type of preventive maintenance. Through routine
maintenance, defects or hidden risks existing on devices can be identified
and eliminated in a timely manner and the health conditions of devices can
be maintained during normal running of the devices. Then, the devices run
securely, stably, and reliably in the long run.

Routine Maintenance Suggestions
Environment/Indicator Maintenance
□Environment conditions:
▪The device shells, internal surface of the devices, dustproof filters inside
the chassis, and the floors are clean and free of dust. Clean or replace
dustproof filters of the cabinets in a timely manner.
▪Ensure that fans run properly during normal running of devices. Shutting
down fans arbitrarily will cause temperature rise inside the devices and
even damage the devices. Do not place sundries at the ventilation
openings of devices, so as not to affect the ventilation and heat dissipation
of cabinet doors and fan trays.
□Indicators:
▪In normal cases, the PWR and SYS indicators on the supervisor are on in
green. For details about indicators, see the RG-RSR77 Series Router
Datasheet.pptx or see the RG-RSR77 Series Router Hardware Installation
and Reference Guide.pdf.

Routine Maintenance Suggestions
Hardware Status Maintenance
□Run the show environment command to display the hardware running status:
▪RSR7708#show environment
Environmental status update at 23:4:53 2013-01-16.
Data is 5 second old, refresh in 30 second(s).
Power Supplies: //Running condition of power modules. "on"
indicates normal.
Power supply 1 is present. Unit is on.
Power supply 2 is present. Unit is on.
Power supply 3 is not present. Unit is off.
Fans working status:OK. //Running condition of the fan module. "OK"
indicates normal.
Temperature readings: //Internal temperature of the chassis
measured at 23 C
Hardware:
CPU name : Freescale MPC85xx.
CPU Speed: 1320M
□If an exception occurs, an alarm will be displayed.

Routine Maintenance Suggestions
Active/Standby Supervisor Election and Status Switching
□Election of active and standby supervisors:
▪After the device with dual supervisors is restarted, the M1 slot is selected as the active
supervisor and the M2 slot is selected as the standby supervisor.
▪When either of the M1 or M2 slot is selected as the active supervisor, if another
supervisor is hot-swapped, the active supervisor keeps unchanged and the inserted
supervisor serves as the standby supervisor.
▪If the standby supervisor is removed during device running, the device will not be affected.
If the active supervisor is removed during device running, the standby supervisor rapidly
serves as the active supervisor.
□Run the show ver slot command to check the active and standby states of supervisors:
▪RSR7708#show version slots
Dev Slot MaxPorts Configured-Module Online-Module Status
--- ---- -------- ----------------- ----------------- ------
1 M1 1 RSR7708-SRCMI RSR7708-SRCMI master
1 M2 1 RSR7708-SRCMI RSR7708-SRCMI slave
□Switching of active and standby supervisors:
▪Run the command to switch the active and standby supervisors:
RSR7708#redundancy forceswitch
▪You can remove and then insert the active supervisor to switch the active and standby
supervisors.

Routine Maintenance Suggestions
Card Status Maintenance
□Run the show version slot command to display the card running status:
▪The Status column displays the current status of cards.
▪The Configured-Module column indicates installed cards.
▪The Online-Module column indicates cards that are actually online.
▪Running: Indicates the normal status. A slot with a card inserted is in the
running state in normal cases.

Routine Maintenance Suggestions
Card Status Maintenance
□Description of Abnormal States of Cards and Restoration Operations
▪Installed: Indicates that a card is virtually loaded but is not actually
inserted. This state occurs in two cases: 1) One card is installed virtually
for command learning or pre-configuration. 2) A card is inserted before but
is removed now.
▫Restoration operation:
–Run the no install command to virtually delete the card of this slot,then
insert the card, and the device automatically identifies the card.
Ruijie(config)#no install 4/1 // 4/1 indicates the slot ID.
▪None: Indicates that no card is inserted and no card is manually installed.
The slot is in the empty state. If a card is actually inserted but is in the
None state, remove the card and insert it again. If the card cannot be
restored to the normal state, a hardware fault may exist.

Routine Maintenance Suggestions
Card Status Maintenance
□Description of Abnormal States of Cards and Restoration Operations
▪Conflict: Indicates the model of an virtually installed card is inconsistent with that of a
card that is actually inserted. Another card has been inserted into this slot before or
manually virtually installed in this slot. As a result, the virtually installed card is
inconsistent with the card that is actually inserted and the card cannot work properly.
▫Restoration operation:
–Run the no install command to manually delete the card of this slot.
–Ruijie(config)#no install 1/1 // 1/1 indicates the slot ID.
–Run the install command to install the card that is actually inserted.
–Ruijie(config)#install 1/1 FNM-4POS-STM1
▪Run-remove: Indicates that a card is powered off by running the remove command.
▫Restoration operation:
–Run the no remove command to power on the card again.
–Ruijie(config)#no remove 1/2
–You can also hot-swap the card so that the card can be re-identified.
