Installing Cards
This chapter describes how to add, remove, and hot-swap management cards and interface
modules in the system. It also covers how to install power adaptor cards.
7.1 Management Modules
This section describes the steps required to add and remove management cards. If you want to
hot-swap management cards, follow the steps below to remove the existing management card
and add the new management card.
"
Be careful when you remove a management card from one MS-7206 and
install it in a different MS-7206 because it is possible that the two MS-7206s
will have the same MAC address.
In the MS-7206 system, the MAC address comes from the management card, not the MS-7206
chassis. Each management card has a different MAC address. The MS-7206 system copies the
MAC address from the active management card when the MS-7206 system starts up. The MS-
7206 system keeps using this MAC address, even if the standby management card takes over,
until the system starts up again. As a result, it is possible for two or more MS-7206 systems to
have the same MAC address at the same time if the same management card was active when
each of them last started up.
• You can install management cards in slot 1 and/or slot 2.
• Install the interface modules in the other slots.
• Leave the slot covers on unused slots.
7.1.1 Add a Management Card (System Is Off)
1 Install the card in the MS-7206 chassis (refer to Section 7.3 on page 54 for details).
2 Turn on the system.
If you insert the management card in slot 1, it automatically becomes the active management
card. If you insert the management card in slot 2, it becomes the standby management card if
there is another management card in slot 1.
