Central Switching Module PTN-CSM310-A/PTN-CSM540-A 9
Release 03 05/2020
...in any other way than described above is not relevant because the CSM that
remains active keeps the current configuration and will overwrite the default
configuration of the reset CSM immediately after it has rebooted.
During the (re)boot of a CSM, its LEDs (see §2.1.2) and display (see §2.1.4) will follow a
boot-cycle. If the entire node boots (single CSM, or both redundant CSMs together), the
node will be reachable again three minutes after the reset has been released. The entire
(re)boot will be finished approximately five minutes after the reset button has been
released. The node is reachable again when it can be discovered and measured by
HiProvision;
CAUTION: A reboot of a single CSM or active CSM (with redundant CSMs) will affect all
communication through this node.
2.1.4
Alphanumeric Display
The 4-character alphanumeric display provides some basic information on the node. The
display shows information during reboot of the node and during normal operation.
a.
During Reboot of the Node
The display reboot cycle takes approximately 20 seconds whereas the reboot of the entire
CSM310-A/CSM540-A takes approximately 5 minutes. After the display reboot cycle, the
display returns to the normal operation cycle, see next paragraph.

step of the display reboot cycle. The CSM can have two firmware loads (active and spare load)
onboard that have been uploaded via HiProvision. If load1 is active, load2 is the spare load and vice
versa. This display cycle shows which firmware load is used to boot the CSM:
Ld1
: Load1 is active and used by the CSM during this boot;
Ld2
: Load2 is active and used by the CSM during this boot;
Ld1t
: The CSM boots with testload1 (=not the active one). This is a result of a commit in the firmware
upgrade phase via HiProvision. If the user accepts this load in HiProvision within 20 minutes, this test
load becomes the active one. If not, the CSM will again reboot with load2 and indicate Ld2;
Ld2t
: The CSM boots with testload2 (=not the active one). This is a result of a commit in the firmware
upgrade phase via HiProvision. If the user accepts this load in HiProvision within 20 minutes, this test
load becomes the active one. If not, the CSM will again reboot with load1 and indicate Ld1;

FAC RST
(optional)
This cycle is only shown if a factory reset has been initiated (see §2.1.3).
Erroneous (re)boot
DDR!
Indicates a hardware failure on the CSM module. Replace the CSM (§2.3.4).
RBT!
Indicates a hardware failure on the CSM module. Replace the CSM (§2.3.4).
NLD!
Indicates an invalid load. Reboot the node. If the problem persists, replace the CSM (§2.3.4).
CLD!
Indicates a corrupt load. Reboot the node. If the problem persists, replace the CSM (§2.3.4).
