Document Revision History

Table 1. Revision History

Date Description

2021-02 9.14.2.9P1 - Added Fixed Issues for the release.

2020–12 Initial release.

Supported Hardware

The following hardware is supported with this platform:

Hardware

Forty-eight fixed 10GBase-T ports supporting 1G/10G speeds

Six fixed QSFP+ ports supporting either one port of 40G or four ports of 10G in breakout mode

Two PSUs

Four fan modules

One MicroUSB serial console port

One universal serial bus (USB Type-A) port for additional file storage

Management Ethernet interface

RS-232 Serial interface

Dual core 1.7GHz Rangeley central processing unit (CPU) system

Temperature monitoring

Software-readable thermal monitor

Real time clock (RTC) support

Two hot pluggable redundant power supplies

Power management monitoring

Four removable fans

Standard 1U chassis

The following lists the individual Dell S4048T–ON system hardware components that are available to order:

Table 2. Hardware Components Available to Order

Fan with airflow from I/O side to PSU side (red — normal air flow direction)

Fan with airflow from PSU side to I/O side (blue — reversed air flow direction)

AC or DC power supply with airflow from I/O side to PSU side

AC or DC power supply with airflow from PSU side to I/O side

NOTE: Fan modules and power supplies are field replaceable units.

NOTE: All fans and PSUs must have the same airflow direction. If you mix the airflow direction, the switch detects the

discrepancy, issues an alarm, and may auto-shutdown to avoid heat damage to components. You must correct the mixed

airflow direction.

Supported Software

The following software is supported with this platform:

Software Minimum Release Requirement

Dell EMC Networking OS 9.14(2.9)

ONIE 3.27.1.10–0

NOTE: For information on non-Dell OS versions, see the Release Notes for the Hardware Platform S4048T–ON.

New Dell EMC Networking OS Version 9.14(2.9) Features

The following features are integrated into the Dell EMC Networking 9.14.2 branch through this release:

Feature Description

OSPFv3 area range support The new area range CLI command allows filtering and

summarizing of OSPFv3 routing information, and advertises the aggregated route. You can configure multiple area range statements under the OSPFv3 process context.

Restrictions

● Prerequisite steps to upgrade the Dell EMC Networking OS from earlier version to 9.14.2.0 or later:

1. Uninstall the older version of the Open Automation (OA) package

2. Upgrade the Dell EMC Networking OS to 9.14.2.0 or later version

3. Install the following OA packages from the respective upgraded version: a. SmartScripts b. Puppet c. Open management infrastructure (OMI) d. SNMP MIB

Prerequisite steps to downgrade the Dell EMC Networking OS from 9.14.2.0 or later to the earlier version:

1. Uninstall the OA package of 9.14.2.0 or later version

2. Downgrade the Dell EMC Networking OS to an earlier version

3. Install the respective OA package from an earlier version

For more information about installing, uninstalling and upgrading the Dell EMC Networking OS and OA package, refer the respective Dell EMC System Release Notes.

● If you downgrade the Dell EMC Networking OS version from 9.14.2.9 to 9.11.0.0 or any older versions, the system displays the following error message even though there is no functional impact:

CDB boot error: C.cdb file format

Before downgrading, save the current configuration and then remove the CDB files (confd_cdb.tar.gz.version and confd_cdb.tar.gz). To remove the files, use the following steps:

DellEMC#write memory DellEMC#delete flash://confd_cdb.tar.gz.version DellEMC#delete flash://confd_cdb.tar.gz DellEMC#reload

● In a VXLAN scenario, hybrid port is not supported.

● While deploying the system in the normal-reload mode in BMP configuration, use the ip ssh server enable command at the beginning of the startup configuration if the write memory command is used at the end of the configuration.

● You can use non-Dell qualified cables, adapters, and optics in a S4048T-ON switch, but Dell EMC Networking does not guarantee their performance as the S4048T-ON does not support non-Dell qualified 40G transceivers. If you insert a non-Dell qualified 40G transceiver into a S4048T-ON 40GbE port, the switch places the interface in an error-disabled (operationally down) state and generates a syslog message, such as: %S4048LC0640:8 %IFAGT-2-

TRANSCEIVER_UNSUPPORTED_ERROR: Transceiver in slot 1 port 49 unrecognized, putting interface in operational-down state.

To verify the error-disabled status of an interface, enter any of the following show commands.

DellEMC# show inventory media Slot Port Type Media Serial Number F10Qualified

------------------------------------------------------------------- 1 49 UNKNOWN UNKNOWN USC1D6J No** 1 50 QSFP 40GBASE-LR4 UQ90C7B No** 1 51 QSFP 40GBASE-SR4 7503835V009Y Yes 1 52 QSFP 40GBASE-CR4 10190002 No 1 53 QSFP 40GBASE-SR4 FE2429470007 Yes 1 54 Media not present or accessible ** Interface is down(error disabled) as transceiver is not F10Qualified

DellEMC# show interfaces fortyGigE 1/49 fortyGigE 1/49 is up, line protocol is down(error-disabled[Transceiver Unsupported]) ...

● The following features are not available in the Dell EMC Networking OS from version 9.7(0.0): ○ PIM ECMP ○ Static IGMP join (ip igmp static-group)

○ IGMP querier timeout configuration (ip igmp querier-timeout)

○ IGMP group join limit (ip igmp group join-limit)

● You can use the negotiation auto command to turn auto-negotiation on or off only on fiber interfaces operating at 1G

speed.

● If you use the interface range command to select multiple interfaces that are added to the management VRF, the ipv6 address command does not display the autoconfig option. You can configure the autoconfig command on

individual interfaces.

● If you use the interface range command to select multiple interfaces that are added to the management VRF, the ipv6 nd command displays the following options but they do not take effect if you use them:

○ dns-server ○ hop-limit ○ managed-config-flag ○ max-ra-interval ○ mtu ○ other-config-flag

○

prefix

○ ra-guard ○ ra-lifetime ○ reachable-time ○ retrans-timer ○ suppress-ra

● REST API does not support AAA authentication.

● Do not configure the vxlan-instance command on the port, which is configured with the portmode hybrid

command. Do not configure the vxlan-instance enabled port as a member of VLAN, which does not have VXLAN-VNI configuration.

● Half-Duplex mode is not supported.

● When FRRP is enabled in a VLT domain, no flavor of Spanning tree should concurrently be enabled on the nodes of that

specific VLT domain. In essence FRRP and xSTP should not co-exist in a VLT environment.

Work around

S1 — Crash: A software crash occurs in the kernel or a running process that requires a restart of AFM,

the router, switch, or process.

S3 — Major: An issue that affects the functionality of a major feature or negatively effects the network for which there exists a work-around that is acceptable to the customer.

S4 — Minor: A cosmetic issue or an issue in a minor feature with little or no network impact for which there might be a work-around.

Work around describes a mechanism for circumventing, avoiding, or recovering from the issue. It might not be a permanent solution.

Issues listed in the “Closed Caveats” section should not be present, and the work-around is unnecessary, as the version of code for which this release note is documented has resolved the caveat.
