• Make sure that the layer 2 switch connecting the different networks
between the two SMCs provides redundant network feeds to both SMCs.
The switch or hub must also be able to forward multicast packets. The
layer 2 switch must not run Spanning Tree Protocol (STP) because STP
interferes with the VRRP processes.
• Connect each of the SMC management ports to each other by a single
cable.
• Make sure an access list entry is present for the management/cluster
network. Otherwise, when the new SMC tries to join with the existing
one, it does not have network access. To view the access list:
— CLI:
/cfg/sys/accesslist
— Web UI: Administration > Access List
Procedure 20
Installing the redundant SMC
1 Make sure that the first SMC is on and operational.
2 Rack-mount the redundant SMC hardware. See “Hardware installation”
on
page 59 .
3 Connect the power cable for the redundant SMC, but do not turn it on yet.
See “Hardware installation” on
page 59 .
Note: Be sure to connect each network to the same port/interface on
both SMCs. Each SMC must have identical network connections.
4 Connect the ports of both SMCs to their respective subnets. See
“Hardware installation” on
page 59 .

Procedure 21
Preconfiguring the first SMC
It is often helpful to pre-configure the first SMC with the IP addresses used on
the second SMC prior to adding the second to the cluster. Preconfiguration
allows the second SMC to immediately set the IP addresses after the two
SMCs join and limits the number of error messages generated when the
device starts up.
