Can I search ARP and find IPs connect to a switch

I have a switch that is not connected to a network.  There are computers and a network storage device connected to it.  When I run arp -a, nothing shows up.

Is there a way I can search the switch and get MACs and IPs on a switch.  It is a small business switch and there is not interface to connect to the switch directly.

If the switch doesn't allow any management (port mirroring), I don't think there is a _good_ way to do this.  The nasty way to accomplish this would be to flood the arp table on the switch, which would cause the switch to act like a hub...

If you have a small network, you can ping all the addresses on the subnet -- then look at your local arp table.  Anything that isn't local will have the MAC address of the router/gateway, but you'd otherwise have the MAC and IP addresses of the local machines.
What kind of switch is this, I know how to do what you are asking on cisco gear, but as Razmus says depending on the type of switch this may not be possible from the switch.
You can always run a ping sweep within your network to discover the IP address's then run a nbtstat on the ip address to get the mac address as well as a basic dnslookup on the IP address to get the hostname. There is easier ways but this is pretty much the jist of it if you have a PC hooked up to this switch.

How would I do a ping sweep for flood the arp table?

Keep in mind this switch is isolated and not connected to anything; not even the internet.  Only computers are connected to the switch.
do you have either physical or remote access to this switch?

I have remote access to the switch.  This switch is not a managed switch.  It's a switch that works just like a switch that I would buy from Best Buy for home users.  It is a Cisco Small Business switch but there is not interface to do anything.  It is just a 16 port switch.
just download a ping sweep application if you want to go that route. if it's a Cisco small business switch go into the firewall and look for a place that says mac filtering. This should tell you the mac address that that switch has and the IP address's of them as well.

I used Angry IP Scanner to scan IPs on the subnet until I found the ones I was looking for.
