An OptiX OSN 580 chassis is 5U high and case-shaped and features high integration. The chassis can be AC powered or DC powered. A DC powered chassis uses the DC power board PIU, and an AC powered chassis uses the AC power board APIU. In an AC powered chassis, an APIU board occupies two service slots. The PIU and APIU boards cannot be installed in the same chassis. Install the PIU board only in a DC powered chassis and the APIU board only in an AC powered chassis.

Core router configuration and development instructions Basic Configuration
Set the Number of SSH Public Keys Saved on an SSH Client to Be Less Than 20
A device functions as an SSH client, and a user uses this client to log in to an SSH server.
The number of SSH public keys saved on an SSH client must be smaller than 20.
When the number of SSH public keys saved on an SSH client reaches 20, a user cannot log in to a new SSH server using the stelnet command.
Run the display current-configuration | include assign rsa-key command in the user view to check whether the number of SSH public keys saved on the SSH client reaches 20.
Recovery measures:
Delete unneeded SSH public keys.
<HUAWEI> system-view
[HUAWEI] undo ssh client 1.1.1.2 assign rsa-key
Configure ACLs for VTY Channels
If no ACL is configured for VTY channels on a device, the device is exposed to external attacks, which leads to high CPU usage.
ACLs must be configured for VTY channels to control the calling in and calling out rights.

Network Reliability
BFD Configuration Requirements
Configure Consistent Incoming and Outgoing Paths for a BFD for LSP Session

A BFD for LSP session is configured, and the LSP from the source device to the destination device is different from the return LSP or IP path. When the return LSP or IP path fails, the session goes Down, causing an incorrect LSP switchover.
