Dell S3048 ON

Dell Networking S-series S3048 1Gb switch

Hardware overview

• 48-port 1Gb Ethernet 1U switch with 4 x 10Gb SFP+ slots and dual PSU
• Ships with dual PSU as standard
• Front-to-rear airflow (intake through RJ45 ports, exhaust over PSU), with reverse airflow PSUs/fans available
• Runs FTOS (Force10-OS), which supports virtual-link trunking to improve over standard spanning-tree

Standard Base Configuration

• Connect to the switch via serial console (115200 baud, 0/n/1); serial cable comes with switch
• Apply power to switch
• Wait for the switch to boot; takes about 2 minutes
• Abort BMP (config file from network boot) by pressing "A" on start-up
• Press return a few times to get a prompt; enter the following commands to configure the switch

enable
configure
reload-type
boot-type normal-reload
end
write
reload

Switch will reboot with a static config; once complete, press return again to get a prompt and enter configuration commands below:

• Remember to save changes using "end" and "write" commands after making changes
• Any existing port config is lost when you change modes; when the switch next boots, you'll see error messages when loading the config, which you can ignore. These errors won't be shown the next time the switch boots.
• Power down the switch, then power it back up after 60 seconds and check the settings have applied.

Stacking switches

• Up to six switches can be stacked together, using 10Gb ports
• Ports are assigned in order (P49->P50->P51->P52 correspond to stack-groups 0,1,2,3)
• Use the following commands to turn on these ports; e.g. the following commands enable stacking on ports 49 and 50

stack-unit 1 stack-group 0
stack-unit 1 stack-group 1

• Set stack-unit priorities; e.g. here for four switches

stack-unit 1 priority 1
stack-unit 2 priority 2
stack-unit 3 priority 3
stack-unit 4 priority 4

• Once stacked, only the stack master will accept new commands and synchronises the configuration across all stack members

Saving switch details

Use the following commands to get information about the switch for asset sheets:

show version
show system stack-unit 1 

• Record details on customer asset sheet

• Asset Tag / Serial Number
• Firmware revision
• Name
• IP Details of management interface
• Username/password
• Any settings applied that are not part of the standard configuration above

---

Firmware update

• Switches usually ship on latest firmware.
• Upgrade the firmware via CLI
• Upgrade requires the switch to be configured with an IP address
• Ensure stacked switches are running the same firmware

---

Hardware support

• Call Dell on 01344-860456 with the service tag for the machine.
• Each switch has its own service tag, printed on rear side (by PSUs)
• Use this to convert tags to express service codes

---

Cable support

• Use officially branded Dell 10Gb QSFP cables only
• Also works with copper twinAX cables

---
