42 4600 Series IP Telephone Release 2.2 LAN Administrator Guide
● The TFTP and/or HTTP file server and application must be properly administered, as
described in TFTP
on page 62 and HTTP on page 66.
!
CAUTION:
CAUTION: A file server does not need to be available for the Avaya IP Telephones to
operate. The Avaya IP Telephones obtain important information from the script
files on the file server and depend on the application file for software upgrades. If
the file server is not available when the Avaya IP Telephones reset, the
telephones will register with the media server and operate. Some features may
not be available, and restoring those features requires resetting the Avaya IP
Telephone(s) when the file server is available.
● For 4630 and 4630SW IP Telephone environments, if users are to have access to LDAP
directories or corporate Web sites, the appropriate servers must be in place. The 4630/
4630SW Telephones must be appropriately administered in accordance with Server
Administration on page 43.
!
CAUTION:
CAUTION: 4630 IP Telephone Release 1.72 introduced significant software architecture
changes. Thus, unlike most 4600 Series IP Telephones software releases, 4630
IP Telephone Release 1.72 and later cannot be downgraded to a release earlier
than 1.72. Attempting to do so renders the 4630 (and 4630SW, if Release 1.8 or
greater) set inoperable. In addition, if you are upgrading a 4630 from a release
prior to Release 1.61, you must first upgrade to Release 1.61. Then you must
upgrade to the newer Release. You cannot upgrade directly from a pre-1.61
Release to a post-1.61 Release for the 4630.
● For 4610SW/4620/4620SW/4621SW/4622SW/4625SW IP Telephone environments, if
users are to have access to LDAP directories or corporate WML Web sites, the
appropriate servers must be in place. You must download the LDAP Directory Application
software from the Avaya support Web site. You must appropriately administer the
telephones in accordance with Server Administration
on page 43.
Note:
Note: Ensure that all required parameters are configured correctly. For Avaya media
server information, see your administration documentation. For the DHCP and
file servers, see Chapter 4: Server Administration
