Software Upgrade Procedures

Procedure 4, Verify Switch Card Flash

With this procedure you verify the version of ﬂash memory in each node’s switch cards, and upgrade

if necessary.

Requirements to Perform the Procedure

If the veriﬁcation step that follows indicates that switch card ﬂash needs to be upgraded, a console

connection to the NP is required for performance of the upgrade. To do this, you must use either a

console terminal located at the node site or a dial-in modem connected to the TCS HUB modem port.

Caution This operation takes your node out of operation.

Overview

Carry out this procedure for each node in your LightStream 2020 network in turn:

1 Log In as Root

2 Verify Need to Upgrade Switch Card Flash

3 Upgrade Flash

4 Repeat for Redundant Switch (if applicable)

5 Reboot NP

6 Verify Flash Version on All Upgraded Switch Cards

Step 1 You should be logged in as root on the primary NP. If not, log in as root on the primary NP

(see Step 1 to Step 5 in “Procedure 1, Copy New Software to the Distribution Node”).

Verify Need to Upgrade Switch Card Flash

Step 2 Determine the checksum for the switch card ﬂash image.

• First check the switch card in Slot A. To do this, enter the following command:

bash# sysver -s sa -all

If the ﬂash checksum is 0x64A2 for a Release 2 switch card or 0x5D00 for a Release 1

switch card, the speciﬁed switch card already has the latest ﬂash image.

• If there is a second switch card in Slot B, enter the following command:

bash# sysver -s sb -all

As above, if the ﬂash checksum is 0x64A2 for a Release 2 switch card or 0x5D00 for a

Release 1 switch card, the speciﬁed switch card already has the latest ﬂash image.

Note A card whose ﬂash checksum is not as speciﬁed above does not have the latest ﬂash image.

Perform Step 3 through Step 12 of this procedure for each such card. If both cards (or one in a

non-redundant system) have the latest ﬂash image, skip the remaining steps of the procedure

(Step 3 through Step 12).
