Cannot access management interface IP

I cannot access another switch through the management IP.  It is a Cisco SG 500 layer 2 switch that is connected to a Cisco 3750 layer 3 switch,  The SG 500 has 4 vlans(1,50,99,150) with 99 being a management vlan.  The IP address of the SG is  Port 50 on the switch is a trunk port with 1 untagged and 50, 99, and 150 added as a tagged vlan.  The 3750 has vlan 99 created and assigned IP  The 2 switches are connected via ports 50(SG500) and 23(3750).    the pc can ping but not the IP of the management IP of the switch,  the client is connected to an access port on the 3750 in VLAN 1 with its DG being the 3750 switch.
