HP consoles, switches, and accessories HP console switches allow control of multiple servers through one or more KVM consoles for efficient server management. HP Serial Console Servers allow the use of remote consoles or terminals to manage servers and other devices through their serial ports. These - HP 5600 | Deploying HP KVM consoling solutions best practices - Page 4
, the console switch supports up to four simultaneous users per switch (one local user using the local rack mounted console plus three remote users, or four remote users using IP Console Viewer). This switch is recommended as a first tier component and comes with HP IP Console Viewer software that - HP 5600 | Deploying HP KVM consoling solutions best practices - Page 5
of UTP CAT5e cable to connect console switches with traditional KVM and serial interfaces. Figure 5 and Table 1 show and describe the interface adapters. Figure 5.

Server Console Switch. HP interface adapters are exclusively configured for use with an HP IP Console Switch or an HP Server Console Switch. They are not compatible with other KVM devices. The HP IP Console Switch or HP Server Console Switch will not recognize third-party adapters. CAT5 cabling HP - HP 5600 | Deploying HP KVM consoling solutions best practices - Page 7
may restrict KVM access to servers due to port blocking. • Virtual media requirements - Whether firmware or software of individual servers needs to be installed or updated remotely • Remote or integrated Lights-Out functionality • Use of legacy console switches and adapters - Expanding an existing - HP 5600 | Deploying HP KVM consoling solutions best practices - Page 8

KVM consoling: • Network protocol • Network performance • Type of session • User management IPv6 protocol support The latest versions of the HP console switches support IPv4 and IPv6 protocols with the onboard IP Console Viewer, the OSD (Figure 8), and the serial console configuration software - HP 5600 | Deploying HP KVM consoling solutions best practices - Page 11
. However, because it is difficult to accurately predict KVM performance over a network, HP recommends that administrators do the following for KVM sessions: • Use a 100 Mbps (or faster) network. The latest HP IP Console Switches support operation on gigabit Ethernet networks. • Use standard video - HP 5600 | Deploying HP KVM consoling solutions best practices - Page 12
, is best suited for small-to-medium sized networks. The HP IP Console Switch with Virtual Media comes with full LDAP support. LDAP enables system administrators to use directory services for managing remote KVM console switch users with the same efficiency as managing network users and resources - HP 5600 | Deploying HP KVM consoling solutions best practices - Page 13
and LDAP (for authentication and authorization). Note With LDAP operation, if the directory service of the domain controller is unavailable, the built-in, console switch administrator account still has access to the switch and all connected servers. However, a user must log into a connected server - HP 5600 | Deploying HP KVM consoling solutions best practices - Page 14
in LDAP mode: • Console switch query - An attempt by a switch user to perform an action requiring switch administrative rights. In response, the directory will check whether the user has administrator access. • Server query - An attempt by a switch user to view the console of a specific server.

network failures, security issues, denial-of-service events, or bandwidth problems (performance degradation from high traffic). Local KVM consoles use the OSD application that resides in the firmware of the console switch and therefore require no additional software. A user can easily access the OSD - HP 5600 | Deploying HP KVM consoling solutions best practices - Page 17
